Linear-wedge spectrometer
Nettet1. sep. 1990 · The wedge spectrometer design concept incorporates a tapered multilayer thin-film dielectric interference filter mounted in close proximity to a two-dimensional detector array such that each row of detectors receives energy from a different spectral band corresponding to the filter's bandpass at that position. This design concept is … Nettet1. nov. 1996 · The Wedge Imaging Spectrometer (WIS) applies a unique technology to hyperspectral imaging systems, allowing flexibility and high performance in a very compact package. This innovation is based on the use of a linear spectral wedge filter mated directly to an area detector array, avoiding the use of bulky and complex optics required …

NettetA prism is therefore chosen as dispersive system. The main concern of the prism is its non-linear dispersive law. This will be discussed later in the paper. A typical optical design … NettetIn the design, a linear wedge filter is mated to an area array of detectors to achieve two-dimensional sampling of the combined spatial/spectral information passed by the filter. As a result, the need for complex and delicate fore optics is avoided, and the size and weight of the instrument are approximately 50% that of comparable sensors.
