DMD scanner

摘要

A scanning optical system is disclosed. The system consists of a spatial light modulator with minimum diffraction effects that can be scanned line by line, a detector appropriate to the application and appropriate optics. One application of such a system is in the infrared realm. The disclosure eliminates the need for a spinning mirror that is standard is infrared scanning systems. Another application is in photocopying. Using a line scanning device, such as a membrane deformable mirror device, eliminates the need for a moving light bar.
