Abstract

Advances in spatial light modulator (SLM) technology have re-suited in an active search for signal processing algorithms for use withSLMs in incoherent electro-optical systems. This paper presents an effective means of generating tracking algorithms for locating small targets with a single detector using FM reticle theory. A simple "barrel transfor-mation" of a spinning FM reticle pattern to an SLM is shown to allowtracking systems to be constructed with solid state devices and avoids the need for moving parts. Also, SLMs allow the FM patterns to change overtime, allowing adaptive interrogation of targets in a particular region of asystem's field of view
