Optical integrating system

Claim 1

An optical integrating system for integrating light comprising, in combination: a. a light collimating means for providing a light beam of circular cross section; b. a piezoelectric crystal having a mirrored surface positioned to intercept and reflect said light beam; c. electric field generating means coupled to said crystal to pass an electric field therethrough in a direction to cause distortion of said crystal in a manner to vary the curvature of said mirrored surface such that the reflected light beam takes the form of a ring of light of increasing radius as the distortion increases; d. a plurality of rings of fiber optics of varying radii coaxially positioned to define annular receiving areas; e. a concave reflector coaxial with said ring of light to direct said ring of light towards said receiving areas such that successive annular receiving are as intercept said ring of light as its radius increases; f. a plurality of optical delay means respectively coupled to said annular receiving areas; g. a common termination surface optically coupled to said optical delay means, each of said plurality of optical means delaying the light portions successively intercepted by said annular receiving areas by a calculated amount of time such that the successive light portions arrive at said common termination surface substantially simultaneously to thereby provide an integrated pulse of light of greater intensity than the intensity of said original light beam; and h. an optical projection device for receiving and projecting said integrated pulse of light from said termination surface, said electric field generating means providing an electric field variation in a repetitive manner at high frequency to thereby provide a series of integrated light pulses for projection from said termination surface.
