Title: Innovations of Christopher R DeHainaut

Introduction

Christopher R DeHainaut is a notable inventor based in Albuquerque, NM (US). He has made significant contributions to the field of optical technology, holding two patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is the Optical Differential Tilt Sensor. This electrooptical sensor system directly measures the angle between two nearly parallel collimated laser beams. After focusing with a positive lens, the beams pass through a photoelastic modulator, a quarter wave retardation plate, and two polarizers. The beams then hit a lateral cell position sensor. Electrical signals from the lateral cell are processed with special electronics to yield a voltage that is proportional to the angular difference between the two beams. This sensor measures extremely small angles and operates at a high bandwidth, with its primary application being in the control of phased array optical telescopes.

Another significant patent is the Optically Phased Laser Transmitter. This apparatus and technique describe phasing the outputs of a multiplier telescope array used as a laser transmitter. The technique utilizes samples of the transmitted beams to control optical path lengths through the separate telescopes, ensuring that the beams add coherently at the receiver. The phasing concept is applicable to systems that provide inputs to the multiple telescopes by dividing a single laser beam, as well as systems with multiple, phase-locked laser beams. This approach is compatible with both single line and multi-line lasers, and it does not require stringent alignment. The concept includes a procedure to find the zero optical path difference condition and to effect fine control of the optical path lengths through the different telescopes.
