Abstract: A novel tilt-insensitive interferometer geometry is described. The design uses tilt-insensitive optics to simultaneously maintain high throughput and precise interferometric alignment, even in the presence of non-ideal scanning motions. A variety of enhancements to the basic design are described, providing a family of related interferometer designs. These spectrometers have applications in spectrometry, spectral imaging and metrology.

Abstract: A Fourier transform interferometer for rapid scanning of scenes such as explosions wherein an incoming beam of light to be analyzed is split by a beam splitter into a first portion and a second portion. The first portion of the incoming light is sent down one arm of the interferometer where it passes through a rotating scanning cube for changing the path length in that arm of the interferometer. The light is then reflected by a retro mirror and sent back through the scanning cube to the beam splitter for sending a portion of the returning beam to a detector. The second portion of the incoming light is sent down a second arm of the interferometer where it passes through a compensator. The light is then reflected by a retro mirror and sent back through the compensator to the beam splitter for sending a portion of the returning beam to a detector. The first and second portions of the incoming light having differing path lengths interfere and the detector measures the fringes created.

Abstract: Dichroism measurement apparatus includes interferometer means for processing linearly polarized source radiation to provide a beam characterized, for each wavelength, by ellipticity that alternates between left and right circular polarization and between which the beam polarization becomes linear in one direction as the ellipticity alternates from left to right circular polarization, and linear in the orthogonal direction as the ellipticity alternates from right to left circular polarization, the characteristic frequency Nu a of such alternation varying as a function of the wavelength. The interferometer means comprises relatively fixed and movable prisms, both having axes at 45* to the linear polarization direction, and actuating means for effecting such relative movement of said prisms to control the frequencies Nu a.

Abstract: PURPOSE: To perfectly prevent chromatic aberration, by using a movable optical wedge, a fixed optical wedge and a translucent mirror integrated therewith in optical scanning.
CONSTITUTION: The light issued from a light source 10 is passed through a movable optical wedge 55 and a fixed optical wedge 45 while converted to parallel luminous flux 14 by a parabolic surface mirror 70 and reflected by the translucent mirror surface 42 on the translucent mirror substrate integrated with the optical wedge 45 while the reflected light is further reflected by a reflective mirror 50 through the optical wedges 45, 55 to be incident to a detector 24 through the optical wedges 45, 55, the translucent mirror 42, the substrate 40 and a light collecting system 65. On the other hand, the parallel luminous flux 14 passing the translucent mirror surface 42 is reflected by the reflective mirror 50 while the reflected luminous flux is again refleced by the translucent mirror 42 to be incident to the detector 24 through the light collecting system 65. Refractive scanning is performed by the movement of the movable optical wedge 55 to the direction of the arrow 56. Because the optical wedges 55, 45 are formed of the same material and the vertical angles β are made same but the directions thereof are made opposite, chromatic aberration is perfectly prevented.

Abstract: A pseudo-active chemical imaging sensor including irradiative transient heating, temperature nonequilibrium thermal luminescence spectroscopy, differential hyperspectral imaging, and artificial neural network technologies integrated together. The sensor may be applied to the terrestrial chemical contamination problem, where the interstitial contaminant compounds of detection interest (analytes) comprise liquid chemical warfare agents, their various derivative condensed phase compounds, and other material of a life-threatening nature. The sensor measures and processes a dynamic pattern of absorptive-emissive middle infrared molecular signature spectra of subject analytes to perform its chemical imaging and standoff detection functions successfully.

Abstract: Described herein is a hyperspectral imaging system in which a polarising beam splitter, a Wollaston prism, an optical system, and a plane mirror are arranged on an optical axis of the imaging system. An imaging detector is provided on which radiation is focused by an imaging lens. The Wollaston prism is imaged on itself by the optical system and the plane mirror so that translation of the Wollaston prism in a direction parallel to a virtual split plane of the prism effectively provides an optical path length difference that is the same for all points in the object field.
