9.1 Application Information

The DLPC150 controller couples with DLP2010 or DLP2010NIR DMD to provide a reliable solution for many data and video display applications. The DMDs are spatial light modulators which reflect incoming light from an illumination source to one of two positions, with the primary position being into a projection or collection optic. Each specific application typically requires a system-level optical architecture that integrates the DMD, as well as, a particular data format to the DLPC150. For example, in a spectroscopy application, the DLP2010NIR DMD is often combined with a single element detector to replace expensive InGaAs array-based detector designs. In this application, the DMD acts as a wavelength selector diverting specific wavelengths of light through the collection optics into the single point detector by setting specific columns of pixel in the "on" position. All other DMD columns that are "off" divert the unselected wavelengths away from the detector's optical path so as to not interfere with the selected wavelength measurement. The DLPC150 controls the set of patterns that sequentially turns columns of pixels "on" or "off" to scan the desired wavelenght spectrum.

Other applications of interest include machine vision systems, spectrometers, skin analysis, medical systems, material identification, chemical sensing, infrared projection, and compressive sensing.
