Abstract: Methods and designs for providing reduced sensitivity to mirror tilt in Fourier transform spectrometers are disclosed. According to an embodiment for two-directional tilt compensation, the FT spectrometer can include a beam splitter positioned to receive an incoming beam from a light source and split the incoming beam into a first sub-beam and a second sub-beam, a corner-cube retroreflector positioned to receive the first sub-beam from the beam splitter, a dual reflective mirror positioned to receive the first sub-beam from the corner-cube retroreflector at one surface and the second sub-beam at the other surface. An optical path delay can be created using a set of mirrors, tilting the beam splitter and/or a glass cube.

Abstract: A system and method for identifying explosive or other target materials includes the steps of irradiating a first location and a second location spaced apart from the first location from a sample suspected of including explosives with ultraviolet, visible or infrared light, measuring reflected light emanated from the first sample location (R1) and reflected light emanated from the second sample location (R2), and calculating a normalized difference in reflectivity (ΔR/ R), wherein R=(R1+R2)/2 is an average reflectivity. A differential reflection spectrum (DRS) is then generated for the sample where ΔR=R2−R1 is the difference of the reflectivities of the first and the second sample location. One or more explosives if present are identified in the sample based on comparing the DRS for said sample to at least one reference DRS.

Abstract: Miniaturized spectrometer in the form of a probe for determining ingredients of a gaseous or liquid fluid with a light source and a spectrometer, at least one measurement beam, and at least one reference beam. Light from the light source is optionally fanned out and focused, by at least one optical lens, in an essentially parallel beam. At least one measurement beam is passed through a light transparent window from the probe into the fluid being investigated and through an additional light transparent window back in to the probe, and at least one reference beam is guided in the probe interior. A collecting optics device, comprising at least one lens, diverts the beams to the impingement point of the light guide or the inlet of the spectrometer, and a beam selector in the area of the collecting optics device passes through one of the partial beams and interrupts all the others.

Abstract: A dual beam spectophotometer is described in which a beamsplitter is at least partially surrounded by a chopper, the combination of which provide sample and reference beams. An oscillating grating produces a monochromatic light beam scans a selected spectral range of wavelengths. The movement of a second chopper and of the oscillating grating is controlled to alternately pass sample and reference spectrums for detection by a detector and to block all radiation. Detected signals are processed for storage by suitable electronics and a computer. The electronics also control the motion of the oscillating grating and chopper. A set of beamsplitters with distinctly different sample-to-reference beam ratios are provided to add versatility to the spectrophotometer.

Abstract: A spectrophotometer is described, comprising a single light source, a single detector, optics for dually and alternatively reading a sample and a reference, and only one moving part. That moving part is a chopper containing multiple pass-through apertures, each filled with a unique bandpass filter to select wavelengths to specifically illuminate the sample or reference. To inform the spectrophotometer whether and when it is reading the sample or the reference, trigger means are provided in at least twice the number of the pass-through apertures.

Abstract: The present invention is a multiplexer for use with an apparatus for optically analyzing a sample. This multiplexer includes a body portion having a primary inlet port. The light received through the light inlet port is sent through a first fiber optic bundle which may be rotated by a fiber carriage to any of several outlet fiber couplers which may be connected to various samples. A position optical sensor assures proper alignment between the first fiber optic bundle and the fiber couplers by sensing the position of a chopper disc which is mounted to the rotating fiber carriage. Once light is passed through the sample, it is passed back into the multiplexer through inlet fiber couplers. These additional fiber couplers are linked to a second fiber optic bundle leading to a detector fiber coupler which may be connected to a fixed fiber cable.
