摘要： This invention relates to a method for constructing multispectral infrared detectors formed by three HgCdTe photovoltaic elements disposed in the form of a sandwich. According to the invention, each photovoltaic element is constructed by preparing a suitable slice of HgCdTe, by polishing the faces of said slice, by chemically attacking the slice, by heating the slice in the presence of mercury inside a test tube within a furnace having a suitable temperature profile, by constructing the ground contact by catalytic deposition of gold, by cementing the slice onto a support, by depositing a layer of photoresist on the slice, by masking the photoresist with the exception of a small exposure region, by eliminating the photoresist in the exposure region, by grafting the slice and by depositing the upper contact and an entire flecting layer. The individual elements are finally assembled and electrically connected to output terminals.

摘要： A low-voltage bias circuit for a photo-diode includes first and second bipolar transistors with a common base connection and grounded emitters, the photo-diode being connected between the emitter of the first transistor and ground in the reverse polarity direction. A current-mirror circuit uses as the reference current the collector current from the first transistor, which is essentially the photo-current, and produces a feed-back current through the base-emitter junction of the second transistor to hold the voltage across the photo-diode at a near zero value for a wide range in values of photo-current. Thus there is minimum delay in the response of the photo-current to step-functions of the incident light.

摘要： A light-emitting diode of a photo-coupler is energized and de-energized through a connection to a switching means. Radiation from the light-emitting diode directed toward a photosensitive means of the photocoupler, reduces the resistance of the photosensitive means to rendering a switching transistor conductive. The switching transistor is connected to and controlled by the photosensitive means. When the switching means is open, the switching transistor remains conductive for a predetermined time period due to a transient phenomena of a resistance change of the photosensitive resistor.

摘要： A light activated acoustic pinger that is useful for underwater three dimional homing. The pinger includes a spherical lens system, a tone burst generator electronics system and a high pressure water tight encasement. When a light source used by an underwater diver, submersible, underwater television system or navigator is panned on the pinger lens system in either the X or Y planes the ping rate will vary depending upon the incident angle of the light received by the spherical lens. In addition, moving the light toward the pinger in the Z direction will increase the ping rate. From the ping rate and the movement of the light source in the X, Y and Z directions an underwater navigator can determine the direction of the pinger and target. There is no battery drain until the pinger is activated by light and therefore targets that have been lost for several years may still be found based on battery shelf life.

摘要： The output beam from a laser scans an input document and the signal reflected therefrom, corresponding to information on the document, is detected and amplified in a first amplifier and converted to an electrical signal. The laser beam is also sampled prior to scanning the document, the beam being detected and converted to an electrical signal which is then amplified in a second amplifier. The outputs of the first and second amplifiers are coupled to a gain control device. The gain versus control voltage characteristic of the device is selected such that the voltage from the second amplifier controls the voltage output from the device whereby noise present in the output laser beam which modulates the output signal from the first amplifier is substantially eliminated.
