Abstract: A System and Method for Low Signal Knife Edge Wavefront Sensing in an Adaptive Optical System to provide measurement and compensation of aberrations induced by propagation through an optical system and through a turbulent medium to a target. The wavefront sensing method requires a minimum signal level for effective operation by taking advantage of the implicit gain afforded by the knife edge principle and incorporating a means for on-line calibration of the knife edge gain. This particular advantage reduces requirements on the laser utilized to generate a beacon signal for wavefront sensing and reduces requirements on the detectors utilized for wavefront sensing, ultimately reducing cost of the method relative to alternative adaptive optical systems using conventional wavefront sensing methods. The method is suitable for use with a broad range of laser sources, including continuous wave and pulsed laser sources, cooperative and non-cooperative targets.

Abstract: A light source is arranged with a light sensing device in such a way that the sensing device receives transmitted light for a translucent medium or reflected light for an opaque medium. The reading of the sensor is stored, then the same source and sensing device are moved over a reference medium whose absorptivity varies unidirectionally. A comparator compares the reading of the sensor with the stored reading and indicates when they are equal. The relative position of the reference and sensor indicates the absorptivity of the medium. One embodiment uses multiple devices and filters to determine composite color.

Abstract: A system for adjusting the sensitivity of an array of sensors. A plate of ferroelectric material that is divided into elements by a multiplicity of transparent electrodes is positioned adjacent to the sensor array to permit light to transmit through the elements to corresponding sensors. The ferroelectric elements and the sensors are each connected to a shift registers. The output of the sensor array taken from its shift register is fed to a comparator which is also fed by a reference level source. The comparator then feeds the corresponding element in the ferroelectric plate through its shift register.

Abstract: The arrangement includes a light source and a photosensitive unit positioned to receive light from the light source and operative for generating an electrical output signal having a magnitude dependent upon the luminous flux received from the light source. A light-blocking arrangement, for example in the form of a film strip, is positioned intermediate the light source and the photosensitive unit, and is mounted for displacement relative to the photosensitive unit and light source in a predetermined direction along a predetermined path. The light transmittance of the light-blocking arrangement varies in said predetermined direction, so that as the light-blocking arrangement is displaced in said direction the luminous flux received by the photosensitive unit from the light source will vary accordingly. A compensating arrangement establishes a linear relationship between the displacement of the light-blocking arrangement and the magnitude of the light-dependent signal, by automatically varying the luminous flux emitted from the light source towards the photosensitive unit in dependence upon the position of the light-blocking arrangement.
