    Abstract: Aspects of the present disclosure provide a method for wavelength calibration of a spectrometer. The method can include receiving a calibration light signal having first spectral components of different first wavelengths; separating and projecting the first spectral components onto pixels of a detector of the spectrometer; establishing a relation between the first wavelengths and pixel numbers of first pixels on which the first spectral components are projected; calculating first residual errors between the first wavelengths and estimated wavelengths that are associated by the relation to the pixel numbers of the first pixels; receiving an optical signal having a second spectral component of a second wavelength; projecting the optical signal onto a second pixel; and calibrating the second wavelength based on a second residual error calculated based on one of the first residual errors that corresponds to a pair of the first pixels between which the second pixel is located.

    Abstract: Apparatus and methods are described for use with a bodily emission of a subject that is disposed within a toilet bowl. While the bodily emission is disposed within the toilet bowl, light is received from the toilet bowl using one or more light sensors. Using a computer processor, intensities of at least two spectral bands that are within a range of 530 nm to 785 nm are determined, by analyzing the received light, and a ratio of the intensities of the two spectral bands is determined. In response thereto, the computer processor determines that there is a presence of blood within the bodily emission. The computer processor generates an output on an output device, at least partially in response thereto. Other applications are also described.

    Abstract: Disclosed are hyperspectral/multiple spectral imaging methods and devices. A method obtains first and second spectral image datasets of a region of interest (ROI). The first spectral image dataset is characterized by a first spectral range and the second spectral image dataset is characterized by a second spectral range. The method then performs a first spectral analysis on the first spectral image dataset and a second spectral analysis on the second spectral image dataset. Afterwards, the method determines one or more spectral signature(s) at a deeper layer of the ROI.

    Abstract: A spectroscope includes a light receiving element and a wavelength selection filter unit. The light receiving element includes a pixel region where a plurality of pixels are disposed. The wavelength selection filter unit is disposed on the pixel region and includes a plurality of wavelength selection filters. The plurality of wavelength selection filters have transmission wavelength characteristics which are different from each other, and split incident light for each wavelength or each wavelength band. The light receiving element generates a light receiving signal by photoelectrically converting light which is split by the wavelength selection filter and is incident on the pixel region, for each pixel.
