摘要： A liquid crystal light valve projection system is provided with increased optical overshoot, and thereby decreased optical response time, by employing a liquid crystal mixture (52) having molecules substantially perpendicularly aligned to the face of the liquid crystal light valve electrodes (42,70) and axially twisted. The axial twist of the liquid crystal molecules is provided by laying down alignment grooves (90,92,96,98) for the liquid crystal mixture that are oriented with respect to one another, on the opposite alignment layers, by an angle of between about 45.degree. and 90.degree.. This mutually angled orientation of the opposed alignment grooves on the opposed alignment layers causes optical overshoot of the system to vary when the entire liquid crystal cell (34) is rotated relative to the output polarizer (18) about an axis perpendicular to the output face of the cell. This rotation of the cell (34) of twisted perpendicular liquid crystal relative to the output polarizer (18) allows a faster optical rise time to be achieved.

摘要： A spectrometer for use with a desired wavelength range includes an array of filters. Each filter outputs at least two non-contiguous wavelength peaks within the desired wavelength range. The array of filters is spectrally diverse over the desired wavelength range, and each filter in the array of filters outputs a spectrum of a first resolution. An array of detectors has a detector for receiving an output of a corresponding filter. A processor receives signals from each detector, and outputs a reconstructed spectrum having a second resolution, the second resolution being higher than any of the first resolution of each filter. Filters and detectors may be arranged into a plurality of imaging units, each imaging unit including first and second filters and first and second photosensing regions. A processor receives signals from each imaging unit, and generates a reconstructed spatial image comprised of discrete spatial units corresponding to each imaging unit.
