Abstract: A method and apparatus of determining peak positions in a spectrum of data includes providing a spectrum of energy to a sample and measuring the spectrum of energy after contact with the sample to provide a range of spectrum data representative of the sample. The spectrum data is then subjected to a differential calculus operation of an even number to provide a differential spectrum data. The spectrum data and differential spectrum data are combined whereby the characteristics of the components in the sample are enhanced. The combined data is then analyzed so that the components in the sample can be identified.

Abstract: An optical system for a microscopic spectrometer includes an objective, an inverse placed telescope for relaying the image formed by the objective towards a detecting element, and an optical element for focusing the relayed image onto the detecting element. In the preferred embodiments, the inverse placed telescope is disposed after the image plane of a Cassegrain objective, and a paraboloid mirror collects the relayed light from the inverse placed telescope to be focused into an image on the detecting element. The inverse placed telescope has a smaller shading coefficient than the Cassegrain objective, and the size of the image of the pupil of the Cassegrain objective is smaller than the diameter of the secondary mirror of the inverse placed telescope. The image of the shaded diameter in the preferred embodiment, which is caused by the secondary mirror of the Cassegrain objective, is greater than the shading diameter caused by the inverse placed telescope itself.

Abstract: A wavelength-scanning mechanism for a spectrometer utilizes an eccentric disc cam driven by a pulse motor to pivot a diffraction grating with a contact bar fixed thereto. A light source supplies light to the mechanism with a first concave spherical mirror reflecting light to the diffraction grating and reflecting light reflected by the diffraction grating to a zero-order light detector. A second concave spherical mirror reflects light diffracted by the diffraction grating to a diffracted light detector. A controller receives information from the light detectors and controls the pulse motor. At least one cam follower is mounted on the cam at a position eccentric from the rotational axis thereof and slidably contacts the contact bar. Alternatively, the diffraction grating has two contact bars fixed thereto, and the cam follower is pivoted between the contact bars. A method of utilizing the mechanism first determines a center value of zero-order light reflected by the diffraction grating by pivoting the diffraction grating in steps between the time zero-order light is detected until it is no longer detected. The number of steps is divided by two, which yields the center value. Diffracted light is detected at the center value, and the spectral intensity of the detected diffracted light is calculated.

Abstract: A swinging member multibeam interferometer for use in a Fourier Transform spectrometer has a pair of mirrors mounted on the swinging member in spaced-apart opposition with the planes of the mirrors being at right angles to the plane of the swinging member. The mirrors may be flat and parallel, flat and skewed with respect to each other, or chevron-shaped with the ends being closer than the middle or the ends being further apart than the middle. A beam splitter directs a reflected beam to one of the pair of mirrors and a transmitted beam to the other of the pair of mirrors. A pair of fixed mirrors reflect both the reflected beam and the transmitted beam back to the mirror pair and a detector. The swinging member is controllably moved by a driving device having a lever connected to a shaft with a piezoelectric ceramic pile supporting said shaft. Contracting and expanding the piezoelectric ceramic pile by electrically energizing means moves the lever and the shaft which is connected to the swinging member.
