New paper in OLEN about a new method to obtain optical correlation


CorrelationOur last work is published in the journal Optics & Lasers in Engineering, entitled Multiple-order correlations and convolutions using a spatial light modulator with extended phase range. Here we present a new type of optical convolver / optical correlator capable of encoding multiple such operations. The technique is based on obtaining higher powers of a properly designed hologram. This can be obtained in two ways. First, we can recalculate higher powers of the amplitude and phase hologram in a standard spatial light modulator (SLM). Alternatively, we can utilize a phase-only hologram and exploit the properties of an SLM with extended phase modulation range.

The work has been done in collaboration with our colleagues Prof. Jeffrey A. Davis and Prof. Don M. Cottrell, and with Benjamin Gutierrez, from San Diego State University.
