An optical modulation using attenuated total reflection offers several advantages in terms of speed, aperture size, and ease of operation compared to other techniques for amplitude modulation of a collimated light beam. This study developed a simple device consists of a prism separated from a mirror reflecting surface by a small - size gap. Varying the gap thickness changes the intensity of the light reflected off by the base of the prism. This thesis devoted ...
