    摘要： A system for providing high-resolution display for a matrix output device, such as a Photo-Multiplier Tube (PMT) matrix, that requires a substantially less number of amplifiers than prior readout systems. A resistor matrix is coupled directly to the outputs of a matrix output device. The outputs in each row in the matrix are combined and amplified with an amplifier that is at an end of each row. Similarly, the outputs in each column of the matrix are combined and amplified with an amplifier at an end of each column. The amplifiers at the end of each row and column also provide conversion of the signals from a current to a voltage. The converted and amplified signals are then processed, using a simple yet accurate algorithm such as center of gravity interpolation, to determine location and other information. The determined information may relate to detection of photons on the PMTs, for example, and is provided as an output signal from the processing circuitry. The output signal from the processing circuitry can be sent to a display device such as a video monitor for display and further analysis of the determined information. The present imaging readout system provides substantial savings in the cost of production and operation of PMT systems, which typically have thousands of outputs requiring amplification for readout.

    摘要： Plural electronic or optical images are provided in a streak optical system, as for instance by use of plural slits instead of the conventional single slit, to obtain a third, fourth, etc. dimensionnullrather than only the conventional two, namely range or time and azimuth. Such additional dimension or dimensions are thereby incorporated into the optical information that is to be streaked and thereby time resolved. The added dimensions may take any of an extremely broad range of forms, including wave-length, polarization state, or one or more spatial dimensionsnullor indeed virtually any optical parameter that can be impressed upon a probe beam. Resulting capabilities remarkably include several new forms of lidar spectroscopy, fluorescence analysis, polarimetry, spectropolarimetry, and combinations of these, as well as a gigahertz wavefront sensor.

    摘要： A method and apparatus for quickly and easily calibrating a relatively unstable light detector, such as a photomultiplier tube. The system is particularly designed to effect large scale semi-automatic calibration of many photomultiplier tube-preamplifier combinations that may exist in, for example, a laser scanner system. Each preamplifier (10) includes an automatic gain control circuit (20) connected in a loop which is momentarily closed during a calibrate mode when a predetermined level of a calibrated light source (15) is directed upon the associated tube (12). An error amplifier (34) develops a voltage in accordance with the deviation of the video output of the tube from the expected level during calibration, and the error voltage is preferably stored in digital form (38) so that the gain of the preamplifier (10) may be maintained at the calibrated level between successive calibrations. The calibrated light source (15) is chopped to provide alternating bright cycles and dark cycles during the calibration mode. The preamplifiers are calibrated during the bright cycles, while the dark cycles are utilized to restore the direct current level of the video output signal, which restoration occurs in normal operation during horizontal blanking of the video system.
