Abstract: A holographic polymer dispersed liquid crystal (HPDLC) tunable filter exhibits switching times of no more than 20 microseconds. The HPDLC tunable filter can be utilized in a variety of applications. An HPDLC tunable filter stack can be utilized in a hyperspectral imaging system capable of spectrally multiplexing hyperspectral imaging data acquired while the hyperspectral imaging system is airborne. HPDLC tunable filter stacks can be utilized in high speed switchable optical shielding systems, for example as a coating for a visor or an aircraft canopy. These HPDLC tunable filter stacks can be fabricated using a spin coating apparatus and associated fabrication methods.

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: Disclosed herein are systems and methods for performing angled confocal spectroscopy. Angled confocal spectroscopy permits sensitive, non-invasive investigation of numerous analytes in a wide variety of samples, including tissues and bodily fluids. The methods and systems disclosed herein can be used to measure spectroscopic signatures of analytes within well-defined and very small regions of samples, while at the same time achieving superior rejection of signal contributions from analytes within the sample that do not fall within a volume of interest. Accordingly, measurements can be performed at comparatively high signal-to-noise ratios, and can provide information such as concentrations and distributions of sample analytes at high spatial resolution. By using cylindrically-focused illumination light, samples can be excited by a “sheet” of light, allowing spatial signal averaging and enhancing the stability and reproducibility of the measurements.
