摘要： A method and means for controlling the output characteristics of a laser in which the optical axis of the laser output, either within the optical cavity of said laser or outside of said cavity, is transected with a fluid stream. The laser output may either be transected with a fluidic jet such as a jet of gas to modulate the output characteristics or the laser beam positioned by means of a directed flow of liquid across the optical axis thereof.

摘要： A calibration system and method include isotropically diffusing high-intensity light emitted from a detection apparatus, with the diffused light being coupled to at least one optical line, typically an optical fiber. In the preferred embodiment, the apparatus to be calibrated is a light detection and ranging (LIDAR) apparatus and the isotropic diffusion is achieved by means of an integrating sphere. For calibrating distance calculations, the optical fiber includes a reflecting mechanism, such as Bragg gratings, at a fixed and known distance from the input end of the optical fiber. The reflecting mechanisms simulates the presence of a remote object at the known distance. For a velocity calculation, a frequency offset may be introduced to the light propagating through the optical fiber, thereby simulating a Doppler shift induced by a moving object. The simulations of the presence and movement of remote objects are used to calibrate the apparatus.
摘要翻译：校准系统和方法包括各向同性地扩散从检测装置发射的高强度光，其中漫射光耦合到至少一条光线路，通常是光纤。在优选实施例中，要校准的装置是光检测和测距（LIDAR）装置，并且通过积分球实现各向同性扩散。为了校准距离计算，光纤包括诸如布拉格光栅的反射机构，其距离光纤的输入端固定和已知的距离。反射机制模拟在已知距离处的远程物体的存在。对于速度计算，可以将频率偏移引入到通过光纤传播的光，从而模拟由移动物体引起的多普勒频移。使用远程物体的存在和移动的模拟来校准装置。

摘要： An optical keyboard includes an optical panel having optical waveguides stacked together. First ends of the waveguides define an inlet face, and opposite ends thereof define a screen. A projector transmits a light beam outbound through the waveguides for display on the screen as a keyboard image. A light sensor is optically aligned with the inlet face for sensing an inbound light beam channeled through the waveguides from the screen upon covering one key of the keyboard image.

摘要： The absorption of neutrons of a nuclear reactor without producing fissions is reduced by providing selected isotopes of zirconium for fabrication of parts such as cladding, thimble tubes and grids. Specifically, the zirconium is enriched in .sup.90 Zr or is depleted in .sup.91 Zr. The selected isotopes are produced by irradiating Zr(OC.sub.4 H.sub.9).sub.4.sup.t, Zr(OC.sub.5 H.sub.11).sub.4.sup.t and/or Zr(OC.sub.3 H.sub.7).sub.4.sup.t, with radiation from a CO.sub.2 laser tuned to the vibrations of the CO(.sup.90 Zr) bond or the O(.sup.91 Zr) bond.

摘要： A method for controlling the population inversion in a solid state laser material by optically pumping the material with a laser beam having a wavelength corresponding to the absorption band of the laser material and the output of which is spatially and temporally modulated. Spatial and temporal modulations of the population inversion in the pumped material are achieved by means of a two-dimensional spatial modulator positioned between the pump laser beam and the pumped laser material, the modulation being thermo-optically controlled by a scanning electron or laser beam or electro-optically controlled by a scanning electron beam or acousto-optically controlled by a two-dimensional acousto-optical modulator. Utilization of a lens between the spatial modulator and the optical cavity of the laser material permits electronic deflection of the output from said laser material by focusing the beam transmitted through said spatial modulator.
