Optical modulators including incorporated into mobile terminal projector

An optical modulation projector for a mobile terminal, having a control system for outputting a projection control signal and image data, a projection control system for receiving the image data and generating a drive control signal based thereon, comprising:

• a. a light source for emitting light beams;
• b. a diffractive-type optical modulator configured to be driven in response to the drive control signal to modulate incident light from the light source and generating an image based on the drive control signal;
• and
• c. a projection optical system for generating a two-dimensional image from the image received from the diffractive optical modulator.
