Abstract
Directed Infrared Counter Measure (DIRCM) system requires a very large field of regard (FOR) with fast scanning mechanism. There are several mechanisms available for achieving this large field of regard. Most of them use single mirror or two mirror scanning mechanisms Faria et al. (J Aerosp Technol Manag Sao Jose dos Campos 5(4):387–394, 2013 [1, 2]). This requires a larger dome size to accommodate these mirrors. This paper presents opto-mechanical design of an infrared imager with a spiral scanning mechanism to reduce the dome size.
