摘要： A system for the surveillance of terrain and the detection of intrusions over a plane extending into that terrain. A curtain array of light beams is projected along the plane and reflections from the terrain are detected by a sensor array essentially spatially coincident with the array of light sources. The times of flight of the beams are determined, and these characterize the form of the terrain being surveilled. The initial background reflection pattern is acquired and stored by the system. A sudden change in this detected background pattern can be defined as arising from an unexpected reflection, indicative of an intrusion. Signal processing systems are described utilizing modulated laser beams and detection at a frequency at least twice that of the modulation, such that reflected signals arising from the ON and the OFF periods of the laser modulation can be subtracted to eliminate the background signals.

摘要： An aerial balloon system comprising a payload platform suspended from an inflated balloon by means of a balloon cable, and an anchoring cable attaching the platform to an anchor point beneath it. The balloon cable and anchoring cable are attached to the payload platform by means of a connecting element pivotally attached to the platform. The platform may include a servo controlled pitch stabilizing system using the input from a pitch sensor mounted on the platform to control an angular actuator to change the angle which the platform makes with the pivoted connection element. Additionally, the platform may include a servo controlled orientation stabilizing system using the input from an orientation sensor mounted thereon to control the departure of the orientation of the platform from a predetermined orientation. This may be readily accomplished using a variable pitch rotor, the pitch being controlled by the orientation sensor signal.

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.

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.
摘要翻译：一种使用调制CW激光二极管和常规高像素数像素传感器阵列（如CCD或CMOS阵列）的激光指示系统。与现有技术的脉冲激光系统相比，这两种技术，二极管激光器和成像传感器阵列是可靠的，广泛使用的和便宜的技术。这些系统与现有技术的系统不同，它们通过从图像传感器阵列的整个视野内的极少数像素中收集较长时间的光，从而在空间上对激光信号进行滤波。这与现有技术的系统不同，其中激光信号在非常短的时间跨度上临时滤波，但是在视场的很大一部分上。通过对各个像素的信号输出进行空间滤波，可以从照明的激光光斑中减去背景照明。
