Application of LCTV to nonlinear speckle correlator

Abstract The intensity and phase modulation characteristics of a liquid crystal television (LCTV) and its diffraction efficiency as a spatial light modulator are investigated. A nonlinear optical correlator using the phase modulation of an LCTV and the hard clipping property of an Optic RAM detector is proposed. The velocity measurement of a light scattering object is conducted by a real-time speckle clipping correlator based on the proposed method.
