Abstract: An imaging system for obtaining images of a specimen that includes a novel filtering system for filtering radiation emitted from the specimen. The imaging system includes a camera and a novel filter grid that is controllably movable relative to the camera in a manner to move a selected emission filter of a plurality of emission filters carried by the grid into position between the camera and the specimen. The filter carrying grid of the system resides in a plane having X and Y coordinates and the system includes a novel positioning mechanism for controllably moving the filter carrying grid along the X and Y coordinates of the plane in a manner to position a selected one of the emission filters carried by the grid into position between the camera and the specimen.

Abstract: Provided are an optical detection apparatus which can measure multi-channel samples at high speed and various wavelengths using an optical detector and a multi-channel sample analyzer employing the same. The optical detection apparatus includes an optical detector; a filter wheel having at least two color filters connected to each other in the shape of a disk; a plurality of optical channels through which a plurality of beams of light enter the filter wheel; and a mirror unit including a plurality of mirrors for sequentially reflecting the plurality of beams of light transmitted through the filter wheel to the optical detector, wherein the mirror unit rotates together with the filter wheel.

Abstract: A system capable of determining wavefront characteristics, such as air induced wavefront aberrations, includes a field programmable gate array (FPGA) device executing a phase diversity algorithm. The FPGA device can be a stand-alone device or comprise multiple FPGAs. The device receives an “in-focus” and an “out-of-focus” image having a known optical difference from that of the “in-focus” image. The device then performs as many phase diversity algorithm iterations as desired to reach an expression for the wavefront aberrations induced on the collected image data. The resulting wavefront data may be used to produce an enhanced image of the original image data. Example applications include remote sensors and targeting systems, and both passive imaging and active projection systems that compensate for wavefront anomalies.
