Spatial Light Modulator (SLM)

Spatial Light Modulator (SLM). What is SLM?. An device that imposes some form of spatially-varying modulation on a beam of light. It can modulates the intensity or phase of the beam or both the intensity and the phase simultaneously. Hamamatsu X10468 Series.

Periodogram of a sinusoid + spike

Periodogram of a sinusoid + spike. Single high value is sum of sine curves all in phase at time t 0 :. Periodogram of a sinusoid + white noise. White noise is sum of sine curves with equal amplitude but random phases: NOTE THAT BOTH FLAT NOISE AND A SPIKE HAVE FLAT PERIODOGRAMS.
