Abstract: An optical sensor includes a light receiving element in which a current corresponding to the amount of received light flows between one end and the other end thereof, a comparator which compares a voltage at the one end of the light receiving element with a predetermined threshold voltage to output a logical signal based on the comparison result, an initialization circuit which initializes the voltage at the one end of the light receiving element to the threshold value or a voltage approximate to the threshold voltage before detecting the amount of the received light, and a voltage changing circuit which changes the voltage at the one end of the light receiving element by a predetermined voltage after completing the initialization. In the optical sensor, after changing the voltage by the voltage changing circuit, a period until the logical signal output from the comparator is logically inverted is expressed as a value corresponding to the amount of the received light.

Abstract: A photoelectric current and voltage converting circuit includes a light receiving element, an amplifier, a feedback resistor, an offset resistor, a constant current source, and a comparator. A feedback resistor is connected between the input and the output of the amplifier and converts photo current into voltage. An terminal of the offset resistor is connected to the output of the amplifier. The constant current source is connected to another terminal of the offset resistor. The comparator compares the connected point of the offset resistor and the constant current source with a reference voltage and outputs a binary signal. The reference voltage is an input voltage of the amplifier or the divided voltage of the intermediate point of the feedback resistor.

Abstract: A method is described for detecting brightness signals from a multiplicity of light-sensitive sensor elements, in particular CCD lines or arrays, in which the brightness signals are amplified in such a way that an A/D converter which digitizes the amplified brightness signals works in its permissible working range. For the brightness signal of a predetermined sensor element, the gain is reduced in steps, preferably in binary steps, from a maximum gain factor down to a working value at which the A/D converter works in the permissible working range. For each following sensor element, the working value of the respective preceding sensor element is used as the maximum gain factor. The number of changeover operations of the amplifier is considerably reduced and thus the detection time is shortened.

Abstract: A plurality of energy couplers (12) receives signals from an energy pulse, each of the energy couplers (12) having a defined field of view, the field of views of at least some of the energy couplers being overlapping. A transducer (14) converts the signals received from the energy pulse to voltage or current output signals that are then amplified. A threshold circuit (18) triggers when the amplitude of a signal caused by the energy pulse exceeds a predetermined level, and signal processing instrumentation (24) then calculates the source location and/or the intensity and/or the initiation time of the energy pulse based on the timing of the output signals associated with individual energy couplers (12).

Abstract: A system and method for detecting radiation indicative of fire, such as forest fire. In one embodiment, a threshold energy level is determined based on ambient sensor conditions. A sensor unit may be setup to scan a predetermined area for electromagnetic radiation. Any detected electromagnetic radiation may then be band pass filtered to a wavelength range centered about a predetermined frequency associated with the presence of fire. The resulting energy level signal may then be further filter to pass only those signals which exhibit a “flicker” frequency. If the resulting filtered signal exceeds the threshold signal, a fire notification signal may then be generated.

Abstract: In an atomic absorption photometer, depending on a fact whether a background correction is carried out or not, a pattern of a pulse lighting of light sources and a timing of sampling a light receiving signal are changed. Namely, at the time of a background correction measurement, one cycle is divided into three periods, that is, a period of lighting HCL, a period of lighting D2L, and an off period, and at the time of a measurement without a background correction, one cycle is divided into the period of lighting HCL and the off period. Accordingly, at the time of the measurement without the background correction, the period of lighting HCL and the off period become longer, and signal-to-noise ratio of the light receiving signal is improved. Accordingly, an absorbance with high accuracy can be calculated.

Abstract: Methods and systems are disclosed for detecting overheating in an optical device before harmful consequences, such as severe local heating, can result. In one embodiment of the invention, a blackbody emitter is disposed in close proximity to a therapeutic optical fiber to absorb therapeutic radiation at a fault and re-emit blackbody (infrared) radiation. The emitter can be coupled to the fiber but, during normal operation, lies outside the optical path between the output of the laser radiation and the site of treatment. Systems and catheters incorporating such emitters are also described for effective monitoring of the laser power transmitted along the optical fiber within the phototherapy device.
