Abstract: An interferometer that may be used in an infrared spectrometer has a housing with a fixed mirror, a perpendicular moving mirror, and a beamsplitter diagonally between them. A moving bearing is mounted to a stationary bearing for translation back and forth along a longitudinal axis, and the moving mirror is mounted to a support member which itself is mounted to the moving bearing to allow pivoting of the mirror support member about a pivot point. A permanent magnet is mounted to the support member and extends along the longitudinal axis, with one of the poles of the magnet formed at the free end of the magnet along the longitudinal axis. A main magnet coil mounted to the housing has an inner bore which extends around the free end of the permanent magnet such that current supplied to the main coil attracts or repels the magnet to drive the moving bearing and the moving mirror in translation back and forth along the longitudinal axis. Side coils are mounted adjacent to the main coil perpendicular to each other to provide magnetic fields in orthogonal directions to the pole at the free end of the permanent magnet, to selectively apply torque to the support member about its pivot point and pivot the face of the moving mirror. The longitudinal position and the deflection of the face of the moving mirror from a perpendicular can be detected and controlled by control of current supplied to the coils.

Abstract: An optical system for determining aberration in a source beam by comparison of a test beam with a reference beam. The optical system includes a test source for producing a source beam having a spacial intensity distribution including an aberration component, a wavefront analyzer for processing a fringe signal associated with the aberration component, and an interferometer. The interferometer is provided with a beamsplitter for splitting the source beam into a test beam and a reference beam, an imaging device for detecting the test beam and the reference beam, and a mirror disposed in a test beam path for reflecting the test beam toward the imaging device. The interferometer also includes a micromirror disposed in a reference beam path for reflecting a portion of the reference beam toward the imaging device and a piezoelectric translator operatively linked to the mirror and controlled by the wave front analyzer. The mirror is capable of moving relative to the path of the test beam. The micromirror has a lateral dimension not exceeding the approximate lateral dimension of a central lobe of the reference beam as focused thereon by focusing means so that when the test beam is reflected by the mirror and the portion of the reference beam is reflected by the micromirror, the reflected test beam and the reflected portion of the reference beam are both incident upon the imaging device forming an interference pattern including fringes which are converted into the fringe signal.

Abstract: A spectrofluorometric apparatus for obtaining spectral image information comprises a stimulating ray source, which produces a laser beam serving as stimulating rays, and a scanning device, which deflects the laser beam in two directions and causes the deflected laser beam to scan a sample. An optical system separates the fluorescence, which has been produced by the sample when the sample is exposed to the laser beam, from the optical path of the laser beam. A Fourier spectrometric system causes interference to occur with the fluorescence, which has been separated by the optical system from the optical path of the laser beam. The Fourier spectrometric system detects the brightness and darkness of the fluorescence, which are due to the interference, as a detection signal and carries out Fourier transformation on the detection signal. The spectrum of the fluorescence is thus measured for each point on the sample, and two-dimensional spectral image information of the sample is thereby obtained.

Abstract: A focusing interferometer, wherein the focusing and orientation of the different mirrors of the interferometer have been successfully facilitated by combining the focusing mirror and the collimating mirror to provide a single spherical mirror surface and by reversing the paths of light that start from the beam splitter by assembly of mirrors which are arranged back-to-back to reflect to opposite directions such that their optical axes join, each of the mirrors including three flat mirror surfaces that are perpendicular to one another and are arranged to reflect to the direction of the point where the normals of the mirror surfaces intersect.

Abstract: An instrument for chemical spectroscopy with imaging capabilities. A lightsource produces an array of light beams, each of which is made up of a plurality of discrete wavelengths. The array of light beams are modulated by an interferometer, then directed through a sample to an array of detectors. The sample may be a chemical mixture (e.g. a fuel stream in a manufacturing facility) or a body part (e.g. breast, limb, or head). An array of laser or light-emitting diodes provides light at the desired wavelengths and high intensity. The set of wavelengths is selected for a particular kind of analysis, and a specific set of possible absorbing species to be detected. The different wavelengths are guided optically (using fiber optics, lenses, and/or mirrors) into a single lightbeam, or an array of lightbeams. This light is then directed through the sample and onto a detector. The lightsource and detector, or lightsource alone, may be rastered if necessary to form an image. Individual lightbeams in an array may be modulated, polarized, or both so as to improve resolution. The signal from the detector undergoes a Fast Fourier Transform to produce a near-infrared absorption spectrum as a function of wavelength. The absorption spectra can be used to produce an image of the spacial distribution of detected species within the sample. Either the lightsource or detectors can be placed on the end of a probe or catheter for imaging through the wall of a hollow sample.

Abstract: The structure of the invention serves to support mirrors defining a reflective channel, which can dynamically be reciprocally widened and narrowed, as in a two-beam interferometer. It is effectively divided, by pivot points on an intermedial axis, into two opposite portions of equal mass, thus affording to the structure immunization against translational forces transmitted through those points. The opposite portions also have their centers of gravity remotely located, so as to generate a counteracting torque in response to moments of rotational inertia transmitted through the pivot points. In the structure, integrally formed planar pieces are assembled to provide contiguous elongate elements and an interposed connecting web element, a plurality of which web elements produce a flexure joint.

Abstract: Reference light is incident to a Michelson interferometer, in which is obtained a reference interference electric signal which undergoes a sinusoidal variation in accordance with interference of reference light as a movable reflector (14) moves. A direction control signal indicating the direction in which to move the movable reflector (14) is applied from a control circuit (21) to a two-phase signal generator (32B), which derives, from the reference interference electric signal, two-phase signals either one of which leads the other by a phase angle of 90.degree. in accordance with the specified direction. The two-phase signals are fed back to a servo drive circuit (19) and a movement control signal is also applied from the control circuit (21) to the servo drive circuit (19) to control the movement of the movable reflector (14). Thus, the movement of the movable reflector can be controlled with a high degree of accuracy corresponding to the accuracy of the wavelength resolution of the reference light.

Abstract: The position of the moving mirror (20) in a Fourier-transform infrared spectrometer is monitored with a circuit which has an incremental counter formed of a plurality of cascaded up/down counters (82, 84, and 86) that count the pulses received by a laser detector (42) to yield a relative position count. A microprocessor (100) maintains an absolute position count by reading the counters (82, 84, and 86) and updating its absolute position count at regular intervals. A portion of the circuit is dedicated to discriminating the direction of the moving mirror (20) by gating circuitry connected to the digitized output of the laser detectors (42, 44).

Abstract: A start of scan circuit for an FTIR spectrometer includes a mode counter, counting through various states of operation of the moving mirror in the FTIR interferometer, and a positioning counter circuit which counts laser pulses from a positioning laser also directed through the interferometer. By appropriately loading and counting up or down the counter in various states, as determined by the mode counter, the circuit can flexibly control the start of scan of the FTIR so that that start of scan can be selectively varied by switches and/or under software control.
