ABSTRACT:
A light optic data handling system for providing changes in the cross sectional dimension of a substantially collimated monochromatic beam of light by allowing the beam to be directed repeatedly, at Brewster's angle, toward and incident upon a common air/light conducting material interface so as to provide said changes utilizing a minimum of bulk material and space while achieving a very high degree of efficiency in the transmission of light through the system.
