Abstract
An improved passive optical range simulator device used to test the ranging function of the optical radar ranger system by input to a coil of optical fiber having a mirror at its inner terminus that permits such coil to act as an optical delay medium. Improvement resides in inclusion of a partial mirror at the input end of the optical fiber coil to present multiple 'target echo' reflections of the laser pulses back to the optical radar ranger system undergoing test.
