摘要： The invention relates to an apparatus for obtaining an enlarged image of a part of the field of view of an IR camera. A device (4,6) for horizontal deflection and a device (5,17) for vertical deflection deflect IR rays (7) incident on the camera towards detector elements (8). These sense the field of view along parallel scanning lines costituting bands, and generate video signals so that the lines can be presented on a display screen (3). In accordance with the invention the device (5,17) for vertical deflection forms a smaller portion in height of the field of view than normal height thereof. The bands partially overlap each other so that the scanning lines in one band fall in the space between scanning lines in a preceding band. The bands are individually noted in the reading order in separate memory (C, D, E). The data for the lines falling in the space will be noted at addresses which do not correspond to their true position in the field of view. This is corrected by a readout device (31,32) which adjusts the readout to the image screen (3) such that the readout alternates between respective memory parts in the sequential order of the image lines.

摘要： An infrared viewing apparatus is described which comprises an infrared objective, a pivotal mirror, a linear infrared detection array, an amplifier arrangement connected to this array, and a display array which is driven by the amplifier arrangement and is imaged onto a plane of observation via the back of the pivotal mirror. By arranging a beam splitter in the radiation path between the display array and the pivotal mirror, which beam splitter transmits a part of the visible radiation to a line sensor, and by controlling the read-out of this sensor by synchronizing device which detects the movement of the pivotal mirror, an electric signal for remote display purposes can be obtained.

摘要： A method and a device for correcting distortion in an image recorded electronically and built up of picture elements along lines. The distortion arises due to the fact that in a field of view scanned along curved lines (31, 33, 35), the picture elements situated vertically below each other when represented on parallel straight lines are displaced horizontally relatively to each other. The picture elements obtained by scanning the field of view are stored in a memory (10) and fed out to a video screen (20). The picture elements on the representation line associated with the shortest scanning line are fed out unchanged while on lines corresponding to longer scanning lines additional picture elements are inserted at definite distance from each other. The distance is selected in such a manner that the number of inserted picture elements per line is proportional to the difference between the length of the respective line and the length of the shortest line (FIG. 5).

摘要： An optical scanning device, for scanning bundles of parallel rays of light defining a field of view, includes a substantially planar disc, means for rotating the disc on its axis, and a substantially planar reflective member. The disc has a first portion which is reflective and a second portion which is transmissive. The planar reflective member is arranged in a fixed position behind the disc such that the normal to the planar reflective member subtends a nonzero angle with respect to the disc axis. As the disc is rotated, the light rays to be scanned are alternately incident upon the reflective portion of the disc and the transmissive portion of the disc. When the light rays are incident on the transmissive portion, they pass through the disc and are reflected by the fixed reflective member which is arranged behind the disc. Both the reflective portion of the disc and the fixed reflective member reflect the light rays to be scanned onto a fixed detector. Due to the different elevation angles of the disc and the fixed mirror, different bundles of parallel rays of light are scanned onto the detector.

摘要： The radiometric measurement of the temperature of remote targets is usually done with a radiometer having a detector whose field of view is alternately switched between the target and a reference temperature source. The detector output is then used to change the reference source temperature to equal the target temperature. According to the invention the reference source temperature is not changed by the measuring apparatus. The difference in detector signals obtained from the target and reference source is used to calculate the target temperature from the known laws of thermal radiation and the known detectivity and spectral response of the detector. The invention can be incorporated in thermal imaging apparatus using the radiation detector scanned to form the thermal image as the radiometer detector. In such radiometric thermal imaging apparatus an array of detectors is scanned across the scene in a raster and a corresponding visual raster is produced. The output of one of the detectors is sampled at a point in the raster which is identified in the visual raster and which is aligned with the target. The output is also sampled when the detector is receiving radiation from the reference temperature source at a point between scans. The difference signal between these two samples is applied to a microprocessor, together with the reference source temperature, an estimate of target emissivity and the detector parameters. From these inputs the microprocessor is programmed to calculate the target temperature.

摘要： An optical system is disclosed for use with a radiant energy receiver which provides high cold shield efficiency and is compact; further the optical system is temperature tolerant to maintain focus with changes in temperature and wavelength without operator intervention. The optical system has primary utility in the infrared region of the spectrum and where a two dimensional array of detectors senses the infrared radiant energy or flux from the scene of interest. The optical system is comprised of a window for environmental protection and two objective mirrors for folding and focusing the scene of interest on a first focal plane. Relay optical means, which may be comprised of one or more optical elements, relays and relocates the first focal plane to a second focal plane which is coincident with the surface of the two dimensional detector array; the relay optical means also forms an exit pupil (the image of the aperture stop) around which the aperture of a cold shield is positioned to minimize extraneous radiant energy falling on the detector array. Using a positive and negative refractive lens and judicious selection of materials allows the relay optical means to automatically compensate for variation in its index of refraction as a function of temperature and wavelength.

摘要： In a radiation scanning system, scanning is achieved by rotation of two drums about parallel axes. The first drum is rotated at an angular speed s.sub.1 and has n.sub.1 reflective surfaces at a distance r.sub.1 from a first axis of rotation. The second drum is rotated at an angular speed s.sub.2 and has n.sub.2 reflective surfaces at a distance r.sub.2 from a second axis of rotation. The axes are separated by a distance d. A detector is located a distance a from the first axis. The following conditions hold:2 a(n.sub.1 /n.sub.2 -1).sup.2 + 2 d(n.sub.1 /n.sub.2).sup.2 +r.sub.2 (n.sub.1 /n.sub.2).sup.2 =r.sub.1 (2n.sub.1 /n.sub.2 -1).sup.2 , (i)n.sub.1 s.sub.1 =n.sub.2 s.sub.2.
