Abstract: A photon measurement front-end circuit (200, 400, 800, 900) comprises an integral module (210, 410, 910), a comparator (220, 420, 810, 920), a transmission controller (230, 430, 820, 930), a negative feedback module (240, 440, 830, 940) and a photon measurement module (250, 450, 840, 950). The integral module (210, 410, 910) is used for receiving an initial signal from a photoelectric detector and a feedback signal from the negative feedback module (240, 440, 830, 940), integrating the difference between the initial signal and the feedback signal, and outputting an integral signal. The comparator (220, 420, 810, 920) is used for comparing the integral signal with a reference level and generating a comparison result. The transmission controller (230, 430, 820, 930) is used for controlling the transmission of the comparison result by using a clock signal, in order to output a digital signal. The negative feedback module (240, 440, 830, 940) is used for converting the digital signal into the feedback signal and feeding the feedback signal back to the integral module. The photon measurement module (250, 450, 840, 950) comprises an energy measurement module (251, 451), and the energy measurement module (251, 451) is used for measuring, by use of the digital signal, the energy of photons detected by the photoelectric detector. The above-mentioned photon measurement front-end circuit (200, 400, 800, 900) has a simple circuit structure, and therefore power consumption can be reduced and costs can be reduced. Besides, energy measurement is not affected by the starting time of the initial signal.

A voltage drop over the compensation component is smaller than a voltage drop over the APD. A sum of (a) a current that pass through the APD and (b) a current that passes through the compensation component is fixed. The portion of the temperature control module is thermally coupled to the compensation component and to the APD.
