Abstract: The invention is a pneumatically actuated energy collection device. The device includes a support which has an energy collector thereon. A shutter is slidably attached to the support and can be moved between a first “closed” position and a second “open” position. In its first position, the shutter covers the collector and in its second position, the shutter uncovers the collector. The shutter is biased into one of the positions. A chamber is disposed adjacent to the shutter so that when the chamber is pressurized, the shutter bias is overcome and the shutter is moved between the first position and the second position.

Abstract: The present invention provides a velocity matched distributed photodetector/modulator (VMDP) for converting between an optical signal and an electrical signal. The converter has twice the theoretical efficiency of any prior art device. The converter wave-guide core is of uniform cross-sectional thickness and composition along the optical path, which makes it easy to fabricate. The converter includes a passive optical waveguide and a plurality of photodiodes. The photodiodes optically couple in series with the passive optical waveguide and electrically couple in parallel with one another to convey the electrical signal there between. The photodiodes exhibit impedance mismatches that generate reflections of the electrical signal, which contribute to a cancellation of reverse traveling portions of the electrical signal. The passive optical waveguide may be tuned to a band gap at which it exhibits transparency to a characteristic wavelength of the optical signal at a field strength less than a first electrical field strength and absorption of the optical signal at the field strength greater than the first field strength. The photodiodes are electrically biased to generate within the passive optical waveguide localized electric fields. The field strength of these fields is greater than the first electrical field strength, to optically couple the photodiodes with the passive optical waveguide.

Abstract: In a method for monitoring the measurement light emitted from an illumination apparatus for an optical measuring instrument, a continuous sensing of measurement light parameters is performed. The sensed measurement light parameters are compared to predefined setpoints. Any deviation from the predefined parameter ranges associated with the setpoints is signaled. This signal is used to initiate a lamp exchange on the illumination apparatus, which has multiple lamps that can be selectively switched on and off individually or in groups. Also described is a corresponding illumination apparatus that preferably performs a lamp exchange automatically. The result is to identify a point in time for a lamp change that is optimal with regard to measurement accuracy and the longest possible utilization of the lamps, so that a measurement light quality that remains consistent during continuous operation can reliably be maintained within predefined tolerance ranges.

Abstract: A method and apparatus for measuring the spatial uniformity of the intensity of a radiation beam from a radiation source based on a single sampling time and/or a single pulse of radiation. The measuring apparatus includes a plurality of radiation detectors positioned on planar mounting plate to form a radiation receiving area that has a shape and size approximating the size and shape of the cross section of the radiation beam. The detectors concurrently receive portions of the radiation beam and transmit electrical signals representative of the intensity of impinging radiation to a signal processor circuit connected to each of the detectors and adapted to concurrently receive the electrical signals from the detectors and process with a central processing unit (CPU) the signals to determine intensities of the radiation impinging at each detector location. The CPU displays the determined intensities and relative intensity values corresponding to each detector location to an operator of the measuring apparatus on an included data display device. Concurrent sampling of each detector is achieved by connecting to each detector a sample and hold circuit that is configured to track the signal and store it upon receipt of a “capture” signal. A switching device then selectively retrieves the signals and transmits the signals to the CPU through a single analog to digital (A/D) converter. The “capture” signal. is then removed from the sample-and-hold circuits. Alternatively, concurrent sampling is achieved by providing an A/D converter for each detector, each of which transmits a corresponding digital signal to the CPU. The sampling or reading of the detector signals can be controlled by the CPU or level-detection and timing circuit.
