摘要： A digital-based control data processing system detects during system operation the occurrence of data processing errors. Data processing accuracy is verified by receiving output information developed from system input information in accordance with a first operational function, computing a derived version of the system input information in accordance with a second operational function, and comparing the derived version of the system input information to the actual system input information to determine whether they differ by a predetermined operational tolerance. This method for verifying processing accuracy is especially advantageous for detecting latent software errors which are unique to a particular computer program. The processing system includes display apparatus which develops from the output information a set of display symbols that convey the information on a monitor screen to the pilot. Assigned to each display symbol is an identifying tag which identifies in real time a display symbol that conveys erroneous information.

摘要： A surface inspection system and method is provided which detects defects such as particles or pits on the surface of a workpiece, such as a silicon wafer, and also distinguishes between pit defects and particle defects. The surface inspection system comprises an inspection station for receiving a workpiece and a scanner positioned and arranged to scan a surface of the workpiece at the inspection station. The scanner includes a light source arranged to project a beam of P-polarized light and a scanner positioned to scan the P-polarized light beam across the surface of the workpiece. The system further provides for detecting differences in the angular distribution of the light scattered from the workpiece and for distinguishing particle defects from pit defects based upon these differences.

摘要： The composition of a particle occurring on the surface of a smooth substrate is identified by impinging the surface with a light beam having a strong P-polarized component at an oblique angle of incidence to the surface, and collecting light scattered from the surface at forward, center, and back locations relative to the portion of the surface impinged by the incident beam. The intensities of the light collected at these locations are measured by detectors and converted into signals, and the magnitudes of the signals are compared to correlations of particle material as a function of the relative magnitudes of the forward-, center-, and back-scatter signals so as to identify the material whose correlation most nearly matches the measured detector signals. Preferably, a ratio of the back detector signal magnitude to forward detector signal magnitude is correlated with particle material and back detector signal magnitude. Alternatively or additionally, a ratio of back detector signal magnitude to center detector signal magnitude is correlated with particle material and back detector signal magnitude. Average particle diameter versus back detector signal magnitude is correlated with particle material.

摘要： A system for and a method of synchronous acquisition of pulsed source light performs monitoring of aircraft flight operation. Diode sources of illumination (18, 108, 208) are pulsed (16, 106, 206) at one-half the video frame rate of an imaging camera (36, 136, 236). Alternate frames view the world-scene with lights of interest pulsed on, and then off, respectively. Video differencing (34, 134, 234) eliminates the background scene, as well as all lights not of interest. Suitable threshholding over a resulting array of camera pixel-differences acquires the desired lights and represents them as point symbology on a display (40, 140, 240). In an enhanced vision landing system embodiment, the desired lights (symbols) overlay or are fused on a thermal image of the scene; alternatively, the symbols overlay a visible scene (TV) image.

摘要： A laser system and power control have a polarization state changer that produces in response to an incident beam with selected polarization state at a first wavelength .lambda..sub.1 a beam at .lambda..sub.1 with a desired polarization state. A frequency converter responds to the beam at .lambda..sub.1 with the desired polarization state to produce a frequency converted beam at a second, different wavelength .lambda..sub.2. When the polarization state changer and the frequency converter are located within a laser cavity, the laser system is operable in three different states and produces an output beam at .lambda..sub.1 or .lambda..sub.2, or no output beam, depending on the polarization state changer. In this intracavity configuration the polarization state changer is also operable as a Q-switch. When the polarization state changer and the frequency converter are located outside a laser cavity, the polarization state changer is operable in the whole range between its first and third states; the device thus produces an output beam at .lambda..sub.2, an output beam including components at .lambda..sub.1 and .lambda..sub.2, or an output beam having no component at .lambda..sub.2, again depending on the polarization state changer. In the extracavity configuration the power in the output at .lambda..sub.2 is continuously controllable between a maximum and zero.

摘要： The imaging range finder of the invention includes a radiation transmitter, a transmitting section and a receiving section. The transmitting section directs radiation across an angular field of view by a first rotating mirror having a plurality of facets. The receiving section includes a second rotating mirror also with a plurality of facets which collects any reflected radiation. An image is produced by measuring the intensity of the reflected radiation at numerous points in the field of view. Range is determined by radiation modulation. Range may be determined more precisely at shorter ranges by modulating the radiation to produce two subcarriers and using one subcarrier to supply short range information. The finder is stabilized to preserve imaging and range finding accuracy when it is exposed to vibration or pitch-angle disturbance. The invention also discloses a method of imaging and range finding over very wide angles and at standard picture frame frequencies.
