An expression is derived for the complex amplitude transmittance
ofthe liquid crystal TV (LCTV) and verified experimentally. It is shown
that spatial phase modulation is realizable with good linearity, high transmission
efficiency, and small intensity distortion. Although the commercial
LCTV does not provide a sufficiently large dynamic range for continuous
phase modulation, a dynamic range of 2? can be obtained by making
appropriate changes in the design.
