  • Patent number: 7385165
    Abstract: A multibeam type scanning microscope that has N beams, wherein the system is devised so that the respective beams perform scanning in LM stages in the Y direction at maximum magnification where the discrete scanning direction is the Y direction, thus performing scanning in an area of N×LM stages overall, and scanning is controlled so that the following processes (1) and (2) are successively repeated LK times at a magnification that is 1/LK times the maximum magnification. Here, L, M and N are integers of 2 or greater, and K is a natural number. (1) The respective beams perform scanning in the Y direction at a sampling interval that is LK times that at the maximum magnification. (2) When scanning of LM-K stages is completed in the Y direction, and the repetition is less than the LKth time, the scanning skips ((N?1)×LM-K+1) stages.

  • Patent number: 7378637
    Abstract: A method for processing pulses arriving randomly in time on at least one channel using multiple peak detectors includes asynchronously selecting a non-busy peak detector (PD) in response to a pulse-generated trigger signal, connecting the channel to the selected PD in response to the trigger signal, and detecting a pulse peak amplitude. Amplitude and time of arrival data are output in first-in first-out (FIFO) sequence. An apparatus includes trigger comparators to generate the trigger signal for the pulse-receiving channel, PDs, a switch for connecting the channel to the selected PD, and logic circuitry which maintains the write pointer. Also included, time-to-amplitude converters (TACs) convert time of arrival to analog voltage and an analog multiplexer provides FIFO output. A multi-element sensor system for spectroscopy includes detector elements, channels, trigger comparators, PDs, a switch, and a logic circuit with asynchronous write pointer.

  • Patent number: 7309850
    Abstract: A solar cell or solar module is measured during a short pulse of light in such a way that the resulting data for current and voltage at each light intensity is the same as would be measured under steady-state illumination conditions and therefore predictive of the actual performance of the solar cell or solar module in sunlight. A varying voltage is applied to the terminals of the solar cell during a light pulse so that the instantaneous current at a given voltage and light intensity during the light pulse is the same as would be measured under constant illumination at that same given intensity. A constant voltage is modified by a small signal correction that is proportional to the terminal current. Or, the small signal correction is proportional to the light intensity. An analog feedback circuit is constructed using the terminal current or light intensity for feedback in order to provide the requisite varying voltage. The varying voltage may also be supplied by digital synthesis.

  • Patent number: 7294827
    Abstract: An electronic module adapted to sense light and configured to minimize the entry of stray light into the module. The module includes a housing having an opening through which light enters the housing, a first substrate coupled to the housing, a second substrate on the first substrate opposite the housing, and a chip on the second substrate. The first substrate defines a window aligned with the housing so that light traveling through the housing also passes through window. The second substrate defines an opening aligned with the window, and the chip is located over the opening in the second substrate so that a light-sensing element on the chip senses light passing through the opening. The module is equipped with features that prevent light from entering the module through the second substrate, the first substrate, and between the chip and second substrate.

  • Patent number: 7285793
    Abstract: A system enables indirect determination of a position vector (VR) of a point position (P). The system uses two fixed trackers (10 and 10?) whose absolute positions are known. A movable measuring device (20) provides a rigid rod (25) supporting a pair of reflectors (30 and 30?) which are mounted at fixed positions. A reference point (R) is mounted at a further fixed position on the rod (25) and is on a straight line (L) through the reflectors (30 and 30?). Light beams from the trackers (10 and 10?) acquire the reflectors (30 and 30?) so that when the reference point (R) is positioned at the point position (P), the position vector (VR) of point position (P) is determinate by vector addition.
