Abstract

Advances in spatial light modulator (SLM) technology have resulted in an active search for signal processing algorithms for use with SLMs 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 transformation' of a spinning FM reticle pattern to an SLM is shown to allow tracking systems to be constructed with solid state devices and avoids the need for moving parts. Also, SLMs allows the FM patterns to change over time, allowing adaptive interrogation of targets in a particular region of a system's field of view.
