CA 2599462

The outer space laser speedometer is designed to be carried aboard a space vehicle either manned or unmanned for the purpose of measuring its speed through space by comparing the wave front angles of two separate laser beams at a 90 degree angle to each other and also in phase with each other, both light beams having been created by a single laser by means of a partially silvered mirror beam splitter or optic fibers diverting the light into two separate beams. Speed detection is accomplished by diverting both beams from their 90 degree angle back to parallel where they result in interference patterns which can be viewed through an eye piece or recorded with an electronic camera linked to a computer that calculates the pattern drift into speed.
