Abstract: An image sensor capable of recording both spectral and polarization properties of light using a single chip device includes an at least 2048 by 2048 array of superpixels. Each superpixel includes an array of spectral pixels, and an adjacent array of polarization pixels. Each spectral pixel includes a spectral filter and a stack of photodiodes, where each photodiode has a different quantum efficiency and is, therefore, sensitive to a different wavelength of light passed by the spectral filter. Each polarization pixel includes a polarization filter and a stack of photodiodes, similar to the spectral pixel photodiode stacks.

Abstract: The present invention enables highly accurate analysis when visualizing analysis results in spectral imaging.
An surface analysis method includes: acquiring spectral image data regarding a sample surface with use of a spectral camera; extracting n wavelengths dispersed in a specific wavelength range in the acquired spectral image data, and converting spectrums of the wavelengths in the spectral image data into n-dimensional spatial vectors for each pixel; normalizing the spatial vectors of the pixels; clustering the normalized spatial vectors into a specific number of classifications; and identifying and displaying pixels clustered into the classifications, for each of the classifications.

Abstract: A spectral image capturing method using a spectral camera control device installed in aircraft, the method comprising:
a) setting an exposure time of the spectral camera so that a current exposure time is determined (S2),
b) determining whether or not either an amount of attitude change or an amount of position change of the spectral camera per exposure time exceeds a predetermined threshold based on a spatial resolution of the spectral camera (S4),
c1) when exceeding the predetermined threshold, resetting the current exposure time to be shorter (S5),
c2) when not exceeding the predetermined threshold, not resetting the current exposure time to be shorter, and
d) capturing a spectral image in a snapshot mode with the spectral camera using the reset exposure time,
wherein when the transmission wavelength of the liquid crystal tunable filter is switched while the aircraft is in a stationary flight, steps b) to d) are repeated.

Abstract: Systems for and methods for in situ optimization of tunable light emitting diode sources are disclosed herein. During operation, the systems and methods obtain real-time feedback from an image sensor, and that feedback is used to tune the tunable LEDs. By tuning the tunable LEDs, the best values for the LED spectral output can be selected based on the feedback from the image sensor, and an image with improved contrast is obtained. Alternatively, the amount of time to obtain an image with acceptable contrast is reduced.

Abstract: Apparatus and methods are described for use with feces of a subject that are disposed within a toilet bowl, and an output device. One or more light sensors are configured to receive light from the toilet bowl, while the feces are disposed within the toilet bowl. A computer processor analyzes the received light, and, in response thereto, detects a currently-occurring inflammatory bowel disease episode, and/or a predicted upcoming inflammatory bowel disease episode. The computer processor generates an output on the output device, at least partially in response thereto. Other applications are also described.

Abstract: A method of processing two dimensional optical spectra, such as echelle spectra, is disclosed. The optical spectra comprise sections having a relatively high intensity separated by borders having a relatively low intensity. The optical spectra have been digitized (61) by a detector. The method comprises denoising (62) an optical spectrum, searching (64) for at least one series of neighboring local extrema of the optical spectrum, fitting (65) a line through each series of neighboring local extrema, each line representing a section, identifying (67) any peaks and their respective locations, and storing (68) the lines and the locations of any peaks.
