Abstract: A camera for polarimetric, multispectral imaging is described. Such cameras are used in photonics, computational imaging and multispectral imaging in which both multispectral and polarimetric sensing modalities are used simultaneously for detection, recognition and identification. The camera enables multiple spectral images to be recorded simultaneously using polarizing beamsplitters and mirrors to divide the image according polarimetric and spectral bands. These multiple, polarized images are recorded on a single focal plane array (FPA) simultaneously. An image processor allows for the resolution of the subsequent image to be improved.

Abstract: A fluorescence hyperspectral microscopy system featuring structured illumination and parallel recording includes a light projection sub-system, a detection sub-system, and an electrical controller. The light projection sub-system includes a digital light processing (DLP) module for generating linear excitation light, a first lens set, an optical path allocation element, and an objective lens. The detection sub-system includes a second lens set, a frequency-dividing reflection element, a two-dimensional light detector, and a light collection element. With the detection sub-system performing detection in conjunction with the light projection sub-system, and the electrical controller controlling the DLP module, a two-dimensional moving platform, and the two-dimensional light detector, the fluorescence hyperspectral microscopy system provides increased resolution and can obtain accurate information in spatial and spectral dimensions and hence a four-dimensional hyperspectral image of the object under detection.

Abstract: The invention relates to a system and a method for optical measurement of a target, wherein the target is illuminated, either actively illuminated, reflecting ambient light, or self illuminating, and a measurement light beam received from the target or through it is detected. The prior art optical measurement systems generally include mechanical filter wheels and photomultiplier tubes, which cause the equipment to be expensive, large-sized and often not sufficiently accurate and stable. The objective of the invention is achieved with a solution, in which the illuminating light beam and/or measurement light beam is led through a Fabry-Perot interferometeror a set of two or more Fabry-Perot Interferometers, and the Fabry-Perot interferometer or a set of two or more Fabry-Perot Interferometersis controlled into different modes during the measurement of a single target. The invention can be applied inoptical measurements where, for example, reflectance, absorption of fluorescence of the target is measured.

Abstract: An optical assembly is disclosed including two laterally variable bandpass optical filters stacked at a fixed distance from each other, so that the upstream filter functions as a spatial filter for the downstream filter. The lateral displacement may cause a suppression of the oblique beam when transmission passbands at impinging locations of the oblique beam onto the upstream and downstream filters do not overlap. A photodetector array may be disposed downstream of the downstream filter. The optical assembly may be coupled via a variety of optical conduits or optical fibers for spectroscopic measurements of a flowing sample.
