The property of phase-mostly modulation of the SVGA1 spatial light modulator, which is manufactured by CRL Ltd. in UK., was investigated and the phase shift of (pi) was achieved. The Dammann grating of binary-phase device for fan-out up to 5x5 was designed and the data of the phase device were fed into the liquid crystal display. The 5x5 array of spots was produced. It has been found that the spatial light modulator can be used as a phase modulated binary optical device to realize some functions in the laboratory.
