Abstract: A photometric device with a wide dynamic range. The photometric device includes a constant current generation circuit (104), a fixed clock signal generation circuit (105) which generates a fixed clock signal having a fixed frequency, a photoelectric conversion element (100), a variable clock signal generation circuit (101), and a digital signal generation circuit (103). The fixed clock signal generation circuit generates a fixed clock signal that oscillates at a fixed frequency, from constant current. The variable clock signal generation circuit generates a variable clock signal that oscillates at a frequency proportional to the amount of photocurrent, from photocurrent generated in the photoelectric conversion element. The digital signal generation circuit sets a measurement period using the fixed clock signal, counts the number of pulses of the variable clock signal that oscillates for the measurement period, and outputs a digital signal including the count value as data.

Abstract: The system includes a synchronous voltage-to-frequency converter connected to receive an analog input signal voltage and to generate a train of output pulses. A counter is connected to receive and count the ouput pulses and a digital register is connected to the counter for periodically receiving and storing the count in the counter. A conversion interval timer circuit is connected to control the operation of the counter and the register to determine a conversion interval during which the output pulses form the synchronous voltage-to-frequency converter are accumulated in the counter and then stored in the register. The conversion interval timer circuit is operable to determine the end of a prior conversion interval and the beginning of a new conversion interval in response to a predetermined phase of a predetermined cycle of the ac power line voltage. A timer is provided for exact measurement of the duration of each conversion interval and a multiplier is provided for multiplying the number stored in the register by a function which is a reciprocal of the exact duration measurement from the timer to hereby correct the number for variations in the conversion interval.

Abstract: Described is herein a radiation measuring apparatus in which a detected pulse signal having a wave height value proportional to energy of radiation is transmitted through an optical fiber and a detected pulse signal received from the optical fiber is supplied to an external apparatus. Even if the transmission loss of the optical fiber is subjected to change with passage of time, a monitor pulse signal having a polarity reverse to that of a detected pulse signal is overlapped on the detected pulse signal lest the wave height of the detected pulse signal be not varied on the transmitting side, and a wave height value of a monitor pulse signal passed through the optical fiber is detected to compensate the wave height of the received detected pulse signal using the detected value.
