Abstract: The present disclosure provides a near-infrared absorbing filter, including an absorbing type infrared filtering medium having opposite first and second surfaces; an organic coating layer formed on the first surface of the absorbing type filtering medium for absorbing infrared rays; a first multi-layered film structure formed on the organic coating layer with the organic coating layer disposed between the first multi-layered film structure and the absorbing type infrared filtering medium; and a second multi-layered film structure formed on the second surface of the absorbing type infrared filtering medium. The near-infrared filter of the present disclosure is able to reduce the wavelength difference of T50 and T20 of the incident light within the range of from 0 to 30 degrees to less than 5 nm, thereby reducing chromatic aberration effectively and reducing ghost images of infrared reflections. The disclosure further provides an image sensor including the near-infrared absorbing filter.

Abstract: An optical spectral analyzer for measuring an optical multi-channel signal by separating the multi-channel signal and measuring a plurality of single-channel signals simultaneously. The spectral analyzer can include a demultiplexer configured to receive the multi-channel signal. The multi-channel signal can be a multi-channel wavelength range. The demultiplexer can separate the multi-channel signal into the plurality of single-channel signals including a first single-channel signal and a second single-channel signal. The spectral analyzer can include a plurality of optical paths. The plurality of optical paths can include a plurality of respective detectors for measuring an optical power of the respective single-channel signals. The detectors can convert the optical power of the respective single-channel signals to corresponding electrical signals. In some examples, the spectral analyzer includes a controller configured to obtain the plurality of respective electrical signals simultaneously to correspondingly detect the optical power of the multi-channel signal across the multi-channel wavelength range.

Abstract: A measurement system includes a light source having semiconductor sources, a multiplexer, and one or more fused silica fibers configured to form an output optical beam having one or more optical wavelengths modulated at a modulation frequency. A light beam set-up includes a monochromator forming a filtered optical beam. A measurement apparatus delivers the filtered optical beam to a sample. A receiver receives a spectroscopy output beam generated from the sample by the filtered optical beam. The receiver is configured to use a lock-in technique that detects the modulation frequency, and to generate first and second signals responsive to light received while the light source is off and on, respectively. The measurement system improves a signal-to-noise ratio of the spectroscopy output beam by differencing the first and second signals. The receiver processes the spectroscopy output beam using chemometrics or multivariate analysis to permit identification of materials within the sample.

Abstract: An imaging system and method are presents for use in reconstructing spectral data of an object. The imaging system comprises: an optical unit; a pixel array of a detector; and a data processor for receiving and processing image data indicative of light detected by the pixel array and generating reconstructed spectral data of the object being imaged. The optical unit is configured and operable for applying a predetermined coding to an input light field while creating an optical image thereof on a detection plane defined by the pixel array. Therefore, the image data is a function of the predetermined coding and a spectrum of the object to be determined.
