A CONCEPTUAL MODEL OF THE BACK-SCATTERED FIELD OF LASERS AND THE USE OF THAT MODEL FOR ROTATION DETECTION.
Abstract
With the use of a laser, it is possible to measure rotation of a remote object by two techniques: Rotation can be measured by the laser back-scattered field technique and the Doppler spectrum technique. The motion of the back-scattered field was investigated and found to be related to the motion of the target surface. A surface model was developed for the explanation of all experiments performed on the back-scattered field. From preliminary work on the Doppler spectrum, two side results were obtained: (1) a method was discovered to heterodyne the Doppler signal without an external interferometer and (2) a method to measure rotation by the Staas effect (AD-608 087) was demonstrated. Work on the Doppler technique was not completed because of variations in the target speed. (Author)
