摘要： An aerial platform comprising a kite providing a level of directional stability when elevated by the wind, and an inflated balloon attached above the kite with a cord. The payload is attached to the kite. The physical separation of the balloon from the kite isolates the payload from shocks generated by the balloon. Additional isolation is provided by use of an elastic attachment cord. Electric power is supplied to the aerial platform by means of an optical fiber receiving optical power from a ground-based source, and conversion of the optical power to electrical power on board the platform. In order to provide a strong tether line, the optical fiber is plaited with a jacket braided from high tensile strength fibers. An aerial laser transmitter is described using a ground based laser source transmitting laser power through an optical fiber to an aerial platform for transmission from the platform.

摘要： A laser designator system using modulated CW laser diodes and a conventional high pixel count image sensor array, such as CCD or CMOS array. These two technologies, diode lasers and imaging sensor arrays are reliable, widely used and inexpensive technologies, as compared with prior art pulsed laser systems. These systems are distinguished from the prior art systems in that they filter the laser signal spatially, by collecting light over a comparatively long period of time from a very few pixels out of the entire field of view of the image sensor array. This is in contrast to the prior art systems where the laser signal is filtered temporarily, over a very short time span, but over a large fraction of the field of view. By spatially filtering the signal outputs of the individual pixels, it becomes possible to subtract the background illumination from the illuminated laser spot.

摘要： A system for making distance measurements of remote points using a phenomenon related to the time of flight of an illuminating beam. A modulated beam of light is directed at the target area. The modulated beam has temporally varying information impressed upon it, such that the time of flight of the beam to the target and back can be related to the temporal signature of the received beam. An acousto-optic modulator is used to perform frequency conversion of the modulated light reflected from points in the field, before that light impinges on the pixels of a detector array. The AO modulation frequency is close to the illuminating light modulation frequency, so that the converted mixed frequency falls within the limited parallel reading rate range of the detector array, and contains the temporal signature information of the modulated light received from the target within signals of manageable frequencies.

摘要： Apparatus for optical inspection of a sample includes a detector assembly, which is configured to receive radiation from a focal area on the sample, and a translation mechanism, which is operative to impart motion to at least one of the detector assembly and the sample so that the focal area of the detector assembly translates over the sample along a translation path. A height sensor is positioned in a known location relative to the detector assembly so as to measure a height of the height sensor relative to a point on the sample that is ahead of the focal area by a predetermined distance along the translation path. A controller is adapted to determine an estimated height of the detector assembly, responsively to the height measured by the height sensor along the translation path.

摘要： Apparatus for inspecting a surface of a sample, including a detector and folding optics. The folding optics are configured to receive radiation arising from a first region of the surface and from a second region of the surface. The first region and the second region have a first spatial relationship with respect to each other. The folding optics form from the radiation a first image of the first region and a second image of the second region on the detector, wherein the first image is a linear transformation of the first region and the second image is the linear transformation of the second region. The first image and the second image have a second spatial relationship, different from the linear transformation of the first spatial relationship, with respect to each other.
