Abstract: A radar test system for producing multiple delayed replicas of a radio frequency radar signal is provided. A laser diode is adapted to receive the radar signal and generate a modulated optical wave signal carrying the radar signal. The modulated optical wave signal passes through a fiber optic delay line. The delayed optical wave signal engages a partially transmissive and reflective assembly wherein a first portion of the optical wave signal is transmitted therethrough and a second portion is reflected back to the laser diode. That portion of the optical wave signal reflected back to the laser diode is amplified therein and subsequently regenerated. The signal transmitted through the partially transmissive and reflective assembly is demodulated to extract the optical wave leaving only the radar signal. In this manner, a series of multiple echoes of the radar signal is produced.

Abstract: An attenuated fiducial replica of the far field pattern of a high energy laser beam is obtained by a system and method wherein a first fraction of an incident high energy beam is deflected from one reflective surface of a holey plate and the diffracted orders of the beam are transmitted from the holes to a concave reflector, which reflects diffracted orders toward an opposite reflective surface of the holey plate. A zinc selenide partially reflective member is disposed on-axis between the rear reflective surface and the concave surface for re-reflecting successive fractional portions of the reflected beam a selected number of times to attenuate the beam converging upon a focal plane from an effective focal distance greater than the physical length of the optical system.

Abstract: A microwave oscillator circuit having a voltage controlled oscillator for producing a controllable frequency microwave signal and a high overtone bulk acoustic resonator coupled to receive the signal is provided with a light source for directing a light beam onto the resonator such that the light is diffracted in response to the presence of acoustic waves produced in the resonator by the microwave signal. Diffracted and undiffracted portions of the light beam are measured and compared to provide an indication of resonance phenomena within the high overtone bulk acoustic resonator. This technique is particularly applicable to frequency agile stable local oscillators in radar equipment. Optical data extraction is completely non-invasive with respect to the microwave circuit functions, resulting in unimpaired stable local oscillator operation.

Abstract: A system for characterizing miniature optical sources such as laser diodes is disclosed. In its most convenient form the system includes an optical system for collecting a wide angle beam and collimating the beam into substantially parallel rays. In the substantially parallel beam, equal area angular portions of the wide angle beam should correspond to equal areas in the parallel beam. Optical sensors are utilized to generate signals indicative of the intensity of the parallel optical beam. Digital processing is included to calculate the characteristics of the optical beam from the intensity samples of the parallel beam. In one embodiment, a reflecting plane is positioned between the source and the optical system so that Lloyd's fringes are produced in a measurement plane.

Abstract: An improved passive optical range simulator device which can be used to test the ranging function of an optical radar ranger system having parallel beams leaving and entering. An adapter member provides for mechanical coupling and optical alignment of the simulator device with the ranger system. A focusing lens transforms parallel beams entering and leaving the ranger system into focused beams entering and leaving one end of a coil of optical fiber having a mirror at its opposite end to act as an optical delay medium. A primary tilted-glass-element optical attenuator limits optical energy allowed to reach the optical fiber entrance face, while defecting first surface reflection away from ranger system input. A removable attenuator assembly having oppositely-tilted flat glass elements at the fiber entrance face permits, by substitution, fine adjustment of beam attenuation. An X-Y-Z translation assembly for the fiber entrance face, together with a light source at the opposite end of the fiber, provides for proper alignment with the focused beams.
