A fast light interconnected processor device for image processing includes an image sensor for producing a line scan signal, a one-dimensional line display for producing a light having an intensity representative of the scan signal and an array of light detectors for producing a two-dimensional convolution of the image with a blurring function performed simultaneously with the scanning of the image scene. The image sensor is, for example, a thermal imager (forward looking infrared system) which outputs electrical signals representative of thermal energy emanating from a scene. The one-dimensional line display is, for example, a one-dimensional array of light emitting diodes which converts the electrical signals of the thermal image to a light image. And the array of light detectors is, for example, an array of charge transfer devices positioned to receive the light image and produce the two-dimensional convolution of the image with a blurring function performed simultaneously with the scanning of the image scene for a contrast map. A zero crossing detector may be connected to the light detector array for producing an outline of the image. Also, the one-dimensional line display may be positioned as to the detector array to provide an in-focus image for an automatic low frequency gain leveling device for controlling the incoming signal dynamic range to match the display dynamic range.
An infrared imaging system comprises an optical system for forming an image of a target on an infrared detection array and an automatic focusing mechanism, wherein an output image signal of the infrared detection array is processed in a filter to extract high frequency components therefrom, The automatic focusing mechanism controls the optical system such that the high frequency components in the image signal is enhanced, In order to detect the maximum enhancement of the high frequency components, the high frequency components for the present moment and those for a past moment are compared while driving the automatic focusing mechanism, Further, the infrared imaging system is equipped with a predictive focusing control system that detects a moving speed of the target and activates the automatic focusing mechanism in advance when the moving speed of the target is fast.
A wide field of view imaging system (100). The novel system (100) includes a rotating mirror (18) having two reflective surfaces each surface, respectively, reflecting light from a scene to first and second sensors (10, 12) positioned to receive light from the mirror (18), wherein the first and second sensors (10, 12) each occupy a different portion of the volume surrounding the mirror (18). In the illustrative embodiment, the mirror (18) is a flat, double-sided mirror rotating at a constant velocity about an axis parallel with the surface of the mirror (18). The first and second sensors (10, 12) are all-reflective optical systems, with the first sensor (10) opposite the second sensor (12). In the preferred embodiment, the invention further includes third and fourth opposing sensors (14, 16) clocked 90.degree. from the first and second sensors (10, 12). The first and second sensors (10, 12) cover an outer annulus of the field of view while the mirror (18) rotates a first 90.degree., and the third and fourth sensors (14, 16) cover an inner annulus while the mirror (18) rotates the next 90.degree..
A GEN II FLIR kit having two assemblies mounted on a common platform, the rst comprising a dewar, integral cooler, and imaging optics with scanner folded into a compact unit and the second assembly comprising a set of afocal optics with wide and narrow fields of view.
A sign structure having a display, movable member and computer means creates a unique vehicle for displaying content. In one version, the movable member is adjacent to the display and substantially shields a portion of the display as it traverses thereover. Coordinated content transmitted to the display gives the appearance that the movable member is influencing the displayed content. For example, as the member moves upward an image below the member stretches in size while an image above the member compresses in size until the upper image disappears and the lower image occupies the entire visible portion of the display. This continues as the member traverses up and down over the display. The member may appear to manipulate the images by stretching, compressing, pushing, pulling and/or erasing them.
Stealthcraft are detected by illuminating backgrounds with narrow radar or sonar beams and monitoring this background illumination for the changes that result when these beams are absorbed by such targets, and are ranged by triangulation using two such beams.
