A high spatial resolution computerized electro-optic radiation detector array.
A novel computerized electro-optic detector was designed, constructed, and characterized. The results of the experiments performed were as follows: (1) To obtain a maximum SNR when operating at any radiation intensity, the designed detector must be operated at the lowest temperature-- -5 degrees C in this configuration. This temperature permits a maximum integration time of 9.7 s without signal distortion. (2) The detector was found to be linear in the range of operation studied, 2.8 X 10(-3) to 2.0 X 10(-2) C kg-1 h-1 (11-78 R h-1), with a sensitivity of 4.2 X 10(4) mV per C kg-1 h-1 (10.8 mV per R h-1). (3) A simulated stepped phantom was imaged, illustrating the possibility of positional measurements. (4) Very little blooming was noticed.
