    Abstract: Receiver circuits are provided for detecting a target light source. The circuits include a photocell arranged to detect light impinging thereupon, and a biasing circuit that maintains a constant reverse voltage across, the photocell irrespective of the photocell output. This maintains the capacitance of the photocell at a substantially constant value, and results in faster response times from the photocell. Further, the present invention provides circuits for effectively removing ambient conditions such as daylight from the output. Also, the present invention reduces the amount of signal loss between the photocell output and an amplifier due to loading at the input stage of the amplifier.

    Abstract: A high dynamic range receiver includes a detector that produces a current at a pair of terminals. A first gain element, implemented as a current-to-voltage converter for example, is coupled to the first terminal, receiving the current and generating a first output signal corresponding to the current. A second gain element, implemented as a current-to-voltage converter for example, is coupled to the second terminal, receiving the current and generating a second output signal corresponding to the received current. A switch selectively couples the first output signal or the second output signal to a port based on a comparison of at least one of the first output signal and the second output signal to a threshold.

    Abstract: A method and apparatus for measuring electromagnetic pulses as a function of time. Radiation measurement, including measurement of single-shot, free-space terahertz femtosecond pulses, is realized using an electro-optical modulator in combination with an optical streak camera. This method and apparatus allow measurement of electromagnetic pulses previously unmeasurable due to the time resolution restrictions dictated by the time-frequency correlation.

    Abstract: There is disclosed an apparatus in which when a surface having a curved portion, for example, a tire surface is visually inspected, light is uniformly illuminated on the surface. In this apparatus, an image pickup operation is performed by a CCD for a region to be visually inspected, which is illuminated by turning on LEDs. Based on the image pickup result, a density distribution of the region to be visually inspected is prepared. A difference between a target light quantity and light quantity, which is obtained for each field angle of the density distribution at which the region to be visually inspected is illuminated by each light source unit, is calculated and corrected. This correction allows the quantity of light reflected from the region to be visually inspected on the inner peripheral surface to become uniform.

    Abstract: A modular base for a position sensitive Photo-Multiplier Tube (PS-PMT) that can be connected to other similar modular bases to form arrays of PS-PMTs. X and Y resistor chains are provided within the base to connect all X and Y coordinate anodes from the PS-PMT, respectively. An amplifier is provided at each end of each resistor chain to amplify output signals when the base is used alone; not connected to other bases. Jumpers associated with each amplifier are provided to include the amplifier in the output signal path or bypass the amplifier and connect to jumpers of other bases. When a base is used alone, the jumpers, which provide either an X or Y output signal, are set to include the amplifier in the output signal path. When two bases are connected together, the jumpers are set to bypass their associated amplifiers and connect the respective X or Y resistor chains of the two bases. The present method advantageously maintains the number of required amplifiers for each X or Y coordinate at two, no matter how many bases are used in the a row or column.
