    Abstract: A compact spectrometer system comprising an improved detector is provided herein. The spectrometer system herein disclosed can comprises a filter, a Fourier transform optical element, and a detector. The detector can comprise a custom detector having a shape that corresponds to the pattern of light incident on the detector. The custom detector may comprise a plurality of separate detection areas, each area configured to detect a portion of the light pattern incident on the detector. The custom detector may comprise a material capable of detecting wavelengths in the short-wavelength infrared (SWIR) range. The custom detector may be configured to require a relatively low number of electrical connections such that it may be implemented using standard, low-cost electronic packaging techniques. An improved, custom detector as described herein can provide the functionality of a two-dimensional pixel array detector while being relatively simple and inexpensive to manufacture.

    Abstract: An interferometer system comprising an optical detector including a substrate and a two-dimensional array of pixels disposed on the substrate is provided. The interferometer system may further comprise an interferometer disposed proximate the optical detector without an optical element between the interferometer and the optical detector. The interferometer may include a first plate positioned proximate the substrate and extending over the two-dimensional array of pixels, a second plate spaced apart from the first plate, the first and second plates defining an optical gap between them, and at least one actuatable spacer positioned between the first plate and the second plate and configured to space apart the first and second plates from one another and to selectively alter a thickness of the optical gap.

    Abstract: A spectroscopic analysis apparatus includes a light source section having a first light source and second light source that radiate light fluxes, a wavelength tunable interference filter, an imaging section that captures light having passed through the wavelength tunable interference filter to acquire a first spectroscopic image when the object being imaged is irradiated with the light from the first light source and a second spectroscopic image when the object being imaged is irradiated with the light from the second light source, a pixel detector that detects an abnormal pixel in the first spectroscopic image, and a light amount corrector that replaces the amount of light at the abnormal pixel in the first spectroscopic image with the amount of light at a pixel in the second spectroscopic image that is located in the same position as the abnormal pixel.

    Abstract: A printer includes a spectroscope and a carriage moving unit. The spectroscope includes a wavelength-selective interference filter on which light from a measurement target is incident, and the carriage moving unit moves the spectroscope in an X direction with respect to the measurement target. If the measurement target is a color patch, the spectroscope performs spectrometry by changing a wavelength of light passing through the wavelength-selective interference filter in a first period during which the spectroscope is moved in the X direction, and passes light of an initial wavelength through the wavelength-selective interference filter at a start of measurement and at an end of measurement in the first period. A first output value that is a measured value from the spectrometry at the start of measurement is compared with a second output value that is a measured value from the spectrometry at the end of measurement.

    Abstract: An imaging system color image acquisition including: an image sensor; a tunable spectral filter arranged in an optical path of light propagation towards the image sensor; and a controller connected to the image sensor and to the tunable spectral filter. The controller is configured and operable for generating a colored image by sequentially operating the tunable spectral filter for sequentially filtering light passing towards the image sensor with three or more different spectral filtering curves during three or more corresponding integration time durations. The tunable spectral filter is configured, as an etalon and includes a pair of reflective surfaces. At least one of the reflective surfaces includes a layer of high refractive index of at least n=2.3 or even higher than 3, or a layer of low refractive index, smaller than n=1. The configuration of the etalon provide wide transmission peaks of the spectral curves with full-width-half maximum (FWHM) in the range of about 50 to 80 nm, free spectral range (FSR) of at least 300 nm, and thickness of the etalon in the order to 1 mm or even less.
