Abstract: An infrared line scanning instrument is provided which scans a single line in a field of view of the instrument. The scan is performed by a scanning mirror which is transparent in the visible and reflective in the infrared region of the spectrum. The infrared radiation is applied to an infrared detector which feeds a display in the form of a light-emitting diode array to light an element in the array in accordance with the amplitude of the IR irradiance seen by the instantaneous field of view throughout the scan. The display is superimposed from the back side of the scanning mirror upon the visible field of view seen by the observer and/or a camera. The instrument thus generates a record of the thermal profile of a single line of a viewed target which is spatially correlated with its location on the target.

Abstract: An automatically controlled reference temperature strip for sensing by detors in a thermal imaging system. The signal in each video channel from each related detector is integrated to determine which detector is sensing the hottest target signal and to use the output of this hottest signal video channel for controlling said reference temperature strip.

Abstract: A combination of a wobble-scan infrared (IR) seeker with an unscanned pul laser (L) seeker. Target IR&L energy is passed through a focusing lens system to a wedge filter which is mounted on a rotating gyro-stabilized platform. The filter separates the IR&L signals by reflecting the L signal from its top surface and the IR signal from its bottom, slanted surface. The L signal is focused on a quad cell detector and detected. The IR signal passes through this detector and is sent through a reticle which pulse-codes it. The pulse-coded IR energy is then focused by another lens on an IR detector.

Abstract: An integrated optical-to-electrical signal transducing system and apparatus therefor which, through the use of a novel combination of fiber optics and microelectronics, permits locating the optical signal detection circuits close to their associated preamplifier circuits and remote from sources of interfering signals without losing the ability to do effective optical tracking or seeking. Specific structure including a hybrid microelectronic device package modified to receive optical input signals through a fiber optics terminal incorporated therein is provided to achieve the desired results.

Abstract: Weapons system for both detection and affecting of stationary or moving objects. A laser beam is generated at a relatively low power level and caused to monitor, as by sweeping, a predetermined zone or space. Said laser beam or a portion thereof is reflected by and from an object appearing within said zone or space and is sensed by suitable detection means. The detection means provides the input to a computer which then locks the generator onto said object and simultaneously increases the power emitted therefrom to a predetermined higher, as destructive, value. Friendly objects operating within the same area can be caused to emanate a signal beam which is sensed simultaneously with the sensing of the reflected laser beam and prevents the actuation of the computer.

Abstract: A horizon sensor for satellites comprising a mask with four sets of four openings one of which receives a projected portion of the earth-space transition line, another is in the form of a grating and the remaining two slit-shaped openings include each a detector on which a secondary image of the grating or of the transition are reflected by an oscillating concave spherical mirror to derive therefrom a digitized measuring signal indicating the position of the transition line.

Abstract: In an optical scanning device in which radiation beams from different zones of a field of view are consecutively converged onto a radiation sensitive detector, an optical projection system is included in the radiation path between an objective and an optical cylinder which is provided with optical convergence systems at its circumference. Said projection system conjugates the center of the objective and the center of rotation of the cylinder.
