Abstract: Method for calibrating a spectral imaging device comprises forming first calibration light by illuminating a first calibration region of a calibration sample with illuminating light, forming second calibration light by illuminating a second calibration region of the calibration sample with the illuminating light, measuring a first spectrum of the first calibration light by using the spectral imaging device, measuring a second spectrum of the second calibration light by using the spectral imaging device, and determining or verifying a spectral calibration function of the spectral imaging device by comparing the measured spectra with reference spectra. The spectral calibration function specifies a relation, which associates values of a control parameter with actual spectral positions. The first calibration light has a first spectral peak at a first peak wavelength, and the second calibration light has a second spectral peak at a second peak wavelength.

Abstract: Modulation-encoded light, using different spectral bin coded light components, can illuminate a stationary or moving (relative) target object or scene. Response signal processing can use information about the respective different time-varying modulation functions, to decode to recover information about a respective response parameter affected by the target object or scene. Electrical or optical modulation encoding can be used. LED-based spectroscopic analysis of a composition of a target (e.g., SpO2, glucose, etc.) can be performed; such can optionally include decoding of encoded optical modulation functions. Baffles or apertures or optics can be used, such as to constrain light provided by particular LEDs. Coded light illumination can be used with a focal plane array light imager receiving response light for inspecting a moving semiconductor or other target. Encoding can use orthogonal functions, such as an RGB illumination sequence, or a sequence of combinations of spectrally contiguous or non-contiguous colors.

Abstract: An image sensor (3) includes a light receiving surface on which a plurality of pixels are disposed, and detects a signal photon. A memory (42) stores, as a map, a correspondence between a parameter indicating the position of each pixel on the light receiving surface and the wavelength of the signal photon detected by the pixel. A processor (41) executes arithmetic processing for calculating the spectral characteristic of a sample disposed on an optical path of an idler photon. An optical system (21) includes a moving mirror (209) configured to apply modulation to the phase of 10 quantum interference. The processor (41) acquires, from a predetermined number of pixels disposed on the light receiving surface, a variation in a detection intensity of the signal photon generated by the modulation by moving mirror (209), and calculates the spectral characteristic based on the visibility of the quantum interference obtained from the variation and the map.
