The DMD-NVG: Use of Digital Micromirror Technology for Interference Reduction in Night Vision Systems

The use of image intensifiers in night vision systems provides significant advantages for military missions. Extremely sensitive detectors are currently in use which enable the user to operate effectively in starlight conditions. These advantages, however, can be mitigated by bright sources within the field of view. Effects can range from simple loss of contrast to blinding and resulting loss of hardware or personnel. Because of the widespread use of night vision systems, this significant problem demands a solution. InterScience proposes to leverage our current work in high resolution image intensification and micro-opto-electro-mechanical systems (MOEMS) and apply them to the development of a new optical system for interference mitigation in night vision goggles (NVG) to be used for Navy applications. Exploiting recent developments in digital micromirror display (DMD) technology and using a novel optical arrangement, we intend to demonstrate a compact, DMD-based retrofit to NVG systems. With this goal in mind, Phase I and Phase II represent stepping stones to demonstrate the concept and develop a viable version of the DMD-NVG for the Navy. Phase III commercial spin-offs include surveillance, research applications and recreational use in as well as direct technology transfer to other branches of the Armed Services.
