Abstract: A material identification apparatus 10 uses a spectrograph and detector array detecting a Raman spectrum produced by a sample illuminated by a laser source to recognize a variety of materials. The Raman spectra are produced by materials illuminated by an inexpensive near-infrared multimode laser operated in a pulse mode to deliver between 0.05 and 0.5 joules of photon energy, with the Raman spectra being detected before any significant heating of the sample occurs. The identification apparatus 10 qualitatively determines the chemical composition of reinforced and unreinforced copolymers and composites such as ABS, polypropylene, talc-filled polypropylene, polycarbonate, PMMA, PVB, polyethylene, and PVC, from samples of different colors, layers, and textures with a high degree of success without the need for special sample preparation.

Abstract: A disc serving as a spatial radiation modulator has dispersed radiation filters thereon. Each filter has a transmittance or reflectance modulation function of the form sin2(m&thgr;+p&pgr;/4), where m is a positive integer and p has one of the four values 0, 1, 2, 3. A radiation beam including selected wavelength components is diffracted into an elongated image dispersed according to wavelength. Different wavelength components are focused onto different filters on the modulator and are encoded by correspond filters. Since the modulation functions of the filters are orthogonal to one another, it is possible to extract the amplitude of each wavelength component after it has been encoded or modulated by corresponding filter from the total detected signal during one measurement.

Abstract: A mechanism for aligning the elements of an optical system is disclosed. One aspect of the present invention is an alignment mechanism which includes lead screws placed on opposite corners of the elements to be aligned. The elements are provided with threaded holes of different pitch, and the lead screw is provided with threads of the same unequal pitches as the elements, thereby forming a differential lead screw. The threads include a locking thread which assures a positive lock between the lead screw and the elements to be aligned and eliminates backlash between them. Another aspect of the present invention is an interference fit mechanism which is provided by the employment of a slightly-oversized flexible boss which mates with a cavity. The boss is provided with a thin outer wall capable of flexing when the boss is inserted into the cavity. Yet another aspect of the present invention includes a wobble plate comprising a spherical socket and housing. The housing includes a mounting for an optical element and is rotatable within the socket. Application of an adhesive to the space between the socket and housing secures the relative positions of the socket and housing when the alignment operations have been completed.

Abstract: In an optical spectrometer, a pair of solid state light sources, an optical filter, a photo detector, a servo amplifier and a servo motor are provided for maintaining proper alignment of a diffraction grating with respect to a focal curve having entrance and exits slits. The light sources and photo detector are positioned in registration with a vertical entrance slit and a vertical offset exit slit, respectively, the vertical entrance slit and vertical offset exit slit being positioned symmetrically about the normal of the diffraction grating. The light emitted from one of the sources is diffracted by the grating and imaged on the upper portion of the offset exit slit and the light emitted from the other source is diffracted by the grating and imaged on the lower portion of the offset exit slit. The photo detector generates an error signal, the amplitude of which is specified by the difference between the intensity of the light passed through the upper and lower portions of the offset exit slit and the optical filter. The error signal is applied to the servo amplifier having upper and lower threshold limits. The servo amplifier generates a signal which is applied to the servo motor for controlling the alignment of the diffraction grating and focal curve.

Abstract: Optical systems have uses, such as in spectrometers, for directing a beam. A spectrometer, for example, utilizes an optical system for directing an incident beam toward a sample and receiving a spectroscopy signal from the sample. In various implementations, for example, an optical system may be further configured to move a beam with respect to a target, such as a sample, and still provide a home position where the beam is directed in a stationary configuration. A self-homing (e.g., self-centering) optical system may provide a “home” position in which the beam is directed in a first stationary mode while still allowing a focused beam to be moved with respect to a target in a second dynamic mode.
