Abstract:
A scanning confocal microscopy system and apparatus, especially useful for endoscopy with a flexible probe which is connected to the end of an optical fiber (9). The probe has a grating (12) and a lens (14) which delivers a beam of multi-spectral light having spectral components which extend in one dimension across a region of an object and which is moved to scan in another dimension. The reflected confocal spectrum is measured to provide an image of the region.

Abstract:
Computed tomography imaging spectrometers ("CTIS"s) having color focal plane array detectors are provided. The color FPA detector may comprise a digital color camera including a digital image sensor, such as a Foveon X3® digital image sensor or a Bayer color filter mosaic. In another embodiment, the CTIS includes a pattern imposed either directly on the object scene being imaged or at the field stop aperture. The use of a color FPA detector and the pattern improves the accuracy of the captured spatial and spectral information. OSB/rjf

Abstract:
The invention aims to simplify the design of the known conoscopic measurement devices (10) used for determining the viewing angle-dependent contrast in particular of transmission-operated liquid crystal displays, and to calibrate such a measurement device spectrographically and make it more versatile. This is done according to the invention by dispensing with the conventional projection optics (for forming an image of the interference pattern on a detector array) and making use instead of relatively few individual rapid detectors (18) for spectrally integrating and/or spectrally analysing light measurement. These detectors are connected, directly or as directly as possible via optical waveguide devices (20) in the interference plane to point surface elements in the interference pattern selected according to the angle of view. When optical waveguides (20, 20') which branch off to different detectors are connected, completely different direction-dependent measurements can be made and recorded at precisely the same time and for identical angles of view, as can (in addition to the contrast measurements) saturation measurements and measurements of dynamic switching characteristics.
