摘要： A radiation detector circuit including a pyroelectric detector element and field effect transistor amplifier means. In order to inhibit saturation of the amplifier means under conditions of large transients in the radiation input or progressive changes in radiation input of low magnitude, at least one ultra-low leakage non-linear device is connected in the part of the circuit including the gate electrode of the amplifier means and the detector element. In one embodiment a pair of picoampere diodes are reverse parallel connected across the detector element and the circuit is formed as a hybrid microcircuit device having three external terminal connections. In another embodiment the non-linear device is incorporated in a feedback path between the output side of an amplification stage and the detector element.

摘要： A movable instrument intended for utilization in detecting a difference which is capable of being optically detected between adjacent locations can be constructed so as to include an optical sensor for producing an output which is proportional to the difference between various locations and an illumination source operatively connected to the optical sensor for providing a level of brightness which is proportional to the output of the optical sensor. Such an instrument is preferably a device which is used in determining the temperature of a surface. When the invention is utilized in conjunction with such an instrument the apparent intensity of the light emitted from the illumination source provides a convenient analog indicator facilitating the instrument being pointed at either the hottest or coldest portion of the surface.
