Abstract: A spectroscopic sensor comprises an interference filter unit, a light detection substrate, and a separator. The interference filter unit has a cavity layer and first and second mirror layers opposing each other through the cavity layer and selectively transmits therethrough a predetermined wavelength range of light according to its incident position from the first mirror layer side to the second mirror layer side. The light detection substrate has a light-receiving surface for receiving light transmitted through the interference filter unit and detects the light incident on the light-receiving surface. The separator extends from the cavity layer to at least one of the first and second mirror layers and optically separates the interference filter unit as seen in a predetermined direction intersecting the light-receiving surface.

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.

Abstract: An optical filter is disclosed including two laterally variable bandpass filters stacked at a fixed distance from each other, so that the upstream filter functions as a spatial filter for the downstream filter. This happens because an oblique beam transmitted by the upstream filter is displaced laterally when impinging on the downstream filter. The lateral displacement causes a suppression of the oblique beam when transmission passbands at impinging locations of the oblique beam onto the upstream and downstream filters do not overlap.
