摘要： PURPOSE:To enable the detection of a heat object in a wide temperature range from low to high temperature value with one equipment by introducing light from a heat object from one optical fiber bundle through an optical coupler with two kind of light receiving elements fixed connected in parallel on the same stem. CONSTITUTION:Light receiving elements 4a and 4b have an anode and cathode fixed on the same stem connected in parallel to each other and output thereof is applied to an amplifier. Light radiated from a heat object enters the light receiving elements 4a and 4b through an optical coupler 3 from an optical fiber bundle 1. In the case of a high temperature heat object, a silicon-based light receiving element 4a captures a radiated light therefrom while in the case of a low temperature heat object, a gelumanium-based light receiving element 4b captures a radiated light therefrom. The application of outputs thereof to the amplifier 5 enables the detection on the presence of the heat object ranging from 400 deg.C (low) - 1,500 deg.C (high).

摘要： PURPOSE:To reduce the power consumption, by connecting power supply terminals of an operational amplifier to a positive (or negative) potential and ground potential, connecting a potential dividing the power supply to a non-inverting input terminal, grounding an inverting input terminal via a photodetector and connecting a feedback resistor from the output. CONSTITUTION:A signle power supply only is used as the power supply, and a voltge Vcc/4 dividing the power supply with resistors R1, R2 is applied to the non-inverting input. As a result, the dynamic range is 3Vcc/4; from Vcc/4 to Vcc. Further, the power consumption is Ic.Vcc. In using a positive/negative dual power supply, the non-invering input terminal is grounded and the output is unipolar, then the dynamic range becomes Vcc. Further, the power consumption is 2Vcc.Ic. Thus, the value of power consumption/dynamic range can be made smaller than that of the dual power supply, the power consumption to obtain the same dynamic range can be made smaller, and the single power supply may be used.
摘要翻译：目的：为了降低功耗，通过将运算放大器的电源端子连接到正（或负）电位和接地电位，连接将电源分配到非反相输入端子的电位，将反相输入端子通过一个光电检测器，并从输出端连接反馈电阻。构成：仅使用信号电源作为电源，Vcc / 4的电压Vcc / 4与电阻R1，R2分压供给非反相输入。结果，动态范围为3Vcc / 4; 从Vcc / 4到Vcc。此外，功耗为Ic.Vcc。在使用正/负双电源时，非反相输入端接地，输出为单极，动态范围为Vcc。此外，功耗为2Vcc.I。因此，可以使功耗/动态范围的值小于双电源的功率，可以使得获得相同的动态范围的功耗更小，并且可以使用单个电源。
