Abstract
A processor such as a digital signal processor (DSP) is used to dynamically generate patterns and/or sequences of patterns for a spatial light modulator (SLM), such as a micromirror device, for the purpose of processing light. The combination of the processor and modulator has afforded optical signal processing in the digital domain and programmability that cannot be achieved with conventional analog optical computing.
Claims1
A method of optical signal processing, comprising:
- providing a micromirror array comprised of an array of micromirror elements;
- generating a bit map representing the state of at least some of said micromirror elements, said generation step performed using a digital signal processor to implement a double crescent algorithm;
- and
- applying said bit map to said mirror array to influence the position of said mirror elements.
