Real-time internal radiation dose measurement system.
Measurement of the output signal from the CdTe detector. (a) Current-to-voltage converter (equation describes the output of the converter). (b) Current waveform at each dose rate and an expanded view of one current pulse.
Signal transmission coils and measurement circuit of the communication area.
Internal circuit configuration (internal circuit consists of integrating, PWM, and modulation circuits).
(a) Integrating circuit. (a) (Equation describes the output of an integrating circuit.) (b) Reset pulses and the output of the integrating circuit.
Input signal simulating the signal from the CdTe detector.
Communication area (characterized by relative coil-to-coil displacement and rotation).
