Constant current solid state ionising radiation detector and transducer - includes semiconductor or insulator radiation sensor, connected to feedback control circuit and light emitter

摘要

A solid state radiation transducer (1) having a radiation detector (2) to convert incident radiation into an electrical signal. The signal is transmitted to a switching arrangement (4). The switching arrangement (4) controls a light emitter(s) so that its emitted light (6), which is also incident on the radiation sensor (2), maintains the electrical signal from the sensor (2) constant is a feedback loop. The output signal from the switching arrangement (4) is desirable from the control signal to the light emitter(s) and is proportional to the radiation incident on the radiation sensor (2). USE/ADVANTAGE - The radiation transducer is intended for use is measuring and detecting radiation. The radiation transducer is easy to produce and relatively cheap.
