Abstract: A light guide member includes a columnar light transmission member having an end face as a light incident surface, a light emergent surface on part of a side surface of the columnar light transmission member, and a saw-toothed reflection portion on a surface opposing the light emergent surface. The saw-toothed reflection portion is made up of a plurality of reflection surfaces. An angle of a reflection surface farther away from the light incident surface with respect to a longitudinal direction of the light guide member is larger than an angle of a reflection surface closer to the light incident surface with respect to the longitudinal direction.

Abstract: An auto-ranging densitometer is disclosed for determining the density of a test sample, wherein the densitometer includes a photodetector and an amplifier circuit adapted to produce an output signal proportional to intensity of light on the photodetector. The amplifier circuit has multiple gains that successively increase in an approximately 2:1 ratio increment. An analog to digital converter is adapted to convert the output signal of the amplifier circuit to digital format. A density signal generator circuit is adapted to receive the output of the analog to digital converter, whereby density resolution non-uniformity is minimized due to small gain increments such that the analog to digital converter needs deal with less extreme variations in density resolution.

Abstract: An auto-ranging densitometer includes a photodetector and an amplifier circuit adapted to produce an output signal proportional to intensity of light on the photodetector. The amplifier circuit has multiple gains that successively increase. An analog to digital converter converts the output signal of the amplifier circuit to digital format. A gain select logic outputs a gain code used to select the gain of the amplifier. A density signal generator circuit includes two LUTs, one of the LUTs being adapted to receive the output of the analog to digital converter and produce an output density scaled to include only low order bits; and the other of the LUTs being to receive the gain code and produce an output density scaled to include only high order bits. The outputs of the two LUTs are concantenation added to produce a summation density signal.

Abstract: A switch comprises at least a first layer of a first material and two contact electrodes arranged on opposite sides of the first layer and connectable to different potentials for applying a voltage thereacross. A first layer is adapted to be conducting upon applying a voltage across the contact electrodes when exposed to irradiation through an irradiation source of an energy high enough for lifting charge carriers from the valence band to the conduction band of the first material. The contact electrode arranged on the first side of the first layer is laterally displaced with respect to the contact electrode arranged on the opposite second side of the layer with a lateral distance separating them.

Abstract: An image sensor includes photoelectric converting elements arranged in a column direction. Each of the converting elements generates signal charge. K transfer electrodes (k is a positive integer more than 1) are provided for each of the photoelectric converting elements in the column direction. 2k signal lines are connected to the transfer electrodes for adjacent two of said photoelectric converting elements. The 2k signal lines are used to supply driving clock signals to the transfer electrodes for the adjacent two photoelectric converting elements, respectively. As a result, the signal charges are transferred based on the driving clock signals.

Abstract: An induced pulse diversion circuit (12) senses the presence of pulses in an input signal, particularly &bgr; and &ggr; pulses induced into the photocurrent input to a focal plane readout unit cell (50), and diverts them from a main signal path (14) to a diversion path (16). A pair of gate devices (18,20) control access to the signal and diversion paths, respectively. An inverting amplifier (30) receives the incoming photocurrent and, upon receipt of an induced pulse, produces an output that turns on the diversion path's gate device (20) and turns off the signal path's gate device (18). The invention reduces the occurrence of “toggling” by limiting the negative-going excursions of the inverting amplifier made in response to an induced pulse, so that the amplifier is prevented from being driven into saturation. The relatively few components needed to implement the invention fit within the area allotted to an integrated unit cell, arrays of which are integrated together to form a focal plane array.

Abstract: An electro-optical detection system for detecting objects within the boundaries of a monitored zone, comprises a plurality of LED emitter and photodetector pairs. Each emitter (12) emits a beam of pulses of light energy into the monitored zone, and its paired photodetector (14) detects light energy including light energy from the beam that is reflected from an object within the monitored zone and generates light detection signals. A controller (10) operates the emitter and photodetector pairs and evaluates the light detection signals to discriminate between light energy of beams reflected from an object within the monitored zone and other light energy. The controller can selectively adjust the evaluation of the light detection signals to adjust the effective boundaries of the monitored zone.

Abstract: A photoconductive switch comprises a first layer (1) of a first material sandwiches between two contact layers (2,3). The first layer is adapted to be conducting upon applying a voltage across said contact layers when irradiated by light (5) of an energy high enough for lifting charger carriers from the valence band to the conduction band of the first material. A first (2) of the contact layers is provided with apertures (4) for allowing light applied on the switch to reach said first layer there for making the switch conducting upon applying a voltage across the two contact layers. A thin second layer (7) is arranged on the side of the first contact layers, at least covering the surfaces of the first layer exposed through said apertures and forming an interface to said first layer in said apertures. The second layer is made of a material being able to form a well ordered interface to said first material and having the same or a larger band gap than the latter.
