ANALYSIS AND DATA PROCESSING SYSTEMS

To implement such infrared simulation modeling stands DLP viewers are used. However, they are mostly designed to work in the visible light spectrum. These viewers (optical projectors) can also be used in the near IR due to the curve of spectrum transmission that sharply falls down at the wave length of 2,7 mcm. To provide the possibilities of using them in the distant IR range and to rise their efficiency in the near IR range some modification was fulfilled by replacing the protective glass of the micromirror device onto the transparent glass up to the wave length of 14 mcm (the ZnSe substance was used). A corresponding technology and special equipment have been worked out. Various types of micromirror modulators have been studied and modulators suitable for modification have been selected. As a result stands that are able to work both in the visible and IR spectrum ranges have been created. To illuminate the DMD modulator a thermal radiation source in the corresponding range has been used. Experiments on generating both static objects (various test-objects in the jpg configuration) and dynamic objects (films in the avi format have been conducted). The developed modulators have demonstrated their efficiency as a part of infrared imitation-modeling stands and seem to be promising in designing modern systems of control and dynamic testing of infrared photo receiving devices and systems.
