SYSTEM AND METHOD FOR ENCODED SPATIO-SPECTRAL INFORMATION PROCESSING

摘要

Encoded spatio-spectral information processing is performed using a system having a radiation source (12), wavelength dispersion device (16) and two-dimensional switching array (18), such as digital micro-mirror array (DMA). In one aspect, spectral components from a sample (24) are dispersed in space and modulated separately by the switching array, each element of which may operate according to a predetermined encoding pattern. The encoded spectral components can then be detected and analyzed. In a different aspect, the switching array (18) can be used to provide a controllable radiation source for illuminating a sample (24) with radiation patterns that have predetermined characteristics and separately encoded components. Various applications are disclosed.
