Abstract: The disclosure relates to a micromechanical Fabry-Perot interferometer, wherein the interferometer comprises an at least partly transparent substrate; an illuminated area where the light is passed through the substrate; a reflector on the top surface of the substrate in the illuminated area; an absorbing reflector layer above the reflector in the illuminated area, which absorbs at least some wavelengths of the infrared light; an arrangement for determining the temperature of the absorbing reflector layer; and at least one actuator to adjust the gap between the reflector and the absorbing reflector layer. An advantage of the interferometer of the disclosure is that absorbing reflector layer absorbs the infrared light, and no separate infrared sensor is required. Additionally multiple wavelengths can be detected due to adjustable gap between the reflector and the absorbing reflector layer.

Abstract: Described are a method and apparatus for high-speed phase shifting of an optical beam. A transparent plate having regions of different optical thickness is illuminated by an optical beam along a path of incidence that extends through the regions. The transparent plate can be moved or the optical beam can be steered to generate the path of incidence. The optical beam exiting the transparent plate has an instantaneous phase value according to the region in which the optical beam is incident. Advantageously, the phase values are repeatable and stable regardless of the location of incidence of the optical beam within the respective regions, and phase changes at high modulation rates are possible. The method and apparatus can be used to modulate a phase difference of a pair of coherent optical beams such as in an interferometric fringe projection system.

Abstract: A device for detecting electromagnetic radiation comprises a waveguide and at least one resonator on a substrate, and a low-refractive index region between each resonator and the substrate. The low-refractive index region has a lower refractive index than a material of the resonator. The low-refractive index region may be annular, and may have a width corresponding to a width of a region in which electromagnetic radiation is concentrated in a whispering-gallery resonant mode. The low-refractive index region may be an air gap between the substrate and the resonator. The device may be a spectrometer for detecting a plurality of predetermined wavelengths of electromagnetic radiation.

Abstract: A system is described that combines spectropolarimetry with scatterometry. The system uses an annular mirror and liquid crystal devices to control the angle of the incident light cone, the polarization and wavelength, an imaging setup and one or more video cameras so that spectroseopic-polarimetric-scatterometric images can be grabbed rapidly. The system is also designed to incorporate additional imaging modes such as interference, phase contrast, fluorescence and Raman spectropolarimetric imaging.

Abstract: A system for wide-range spectral measurement includes one or more broadband sources, an adjustable Fabry-Perot etalon, and a detector. The one or more broadband sources is to illuminate a sample, wherein the one or more broadband sources have a short broadband source coherence length. The adjustable Fabry-Perot etalon is to optically process the reflected light to extract spectral information with fine spectral resolution. The detector is to detect reflected light from the sample, wherein the reflected light is comprised of multiple narrow-band subsets of the illumination light having long coherence lengths and is optically processed using a plurality of settings for the adjustable Fabry-Perot etalon, and wherein the plurality of settings includes a separation of the Fabry-Perot etalon plates that is greater than the broadband source coherence length but that is less than the long coherence lengths.
