Dosimeter for photometric applications |
摘要 |
A temperature independent dosimeter is provided for measuring an amount of irradiation of a predetermined frequency. A photodiode (24) operating in its photovoltaic mode is irradiated with the irradiation to produce a signal that is amplitude-proportional to the amplitude of the irradiation. The signal is converted by a pair of operational amplifiers (89, 96) to a plurality of pulses that are proportional in frequency to the amplitude of the signal. The plurality of pulses is counted by a counter (20) and the irradiation is terminated when the count reaches a predetermined amount.
