摘要： A photodetector disclosed herein comprises an avalanche transistor having a reference junction structure in which temperature characteristics of a current amplification factor are about the same as those of an avalanche photodiode and which is reverse-biased, and a current injection junction structure which injects a reference current to the reference junction structure and which is forward-biased. Voltages to be applied to the avalanche photodiode and the reference junction structure are controlled so that the amplification factor of the reference current amplified in the reference junction structure is retained at a predetermined value, whereby the temperature characteristics of the photodetector utilizing an avalanche effect can be stabilized.

摘要： An optical rangefinder based on time-of-flight measurement, radiates pulsed light toward an object (70), and receives reflected light from the object, the receiver operating in a photon counting mode, so as to generate a pulse for a detected photon. There is a variable probability of a photon detection on the receiver, and a controller (370, 380, 390; 365, 470, 475, 380, 390; 570, 580, 590, 390) controls the photon detection probability of the receiver, based on a light level. By controlling the detection probability according to a light level, the receiver can have an increased dynamic range, and without the expense of using optical components. This can apply even while detecting very weak signals since the receiver can still be in a photon counting mode while the detection probability is controlled. The light level can be indicated by an output of the receiver itself, or by another detector external to the receiver.
摘要翻译：基于飞行时间测量的光学测距器将朝向物体（70）的脉冲光辐射，并且接收来自物体的反射光，接收器以光子计数模式工作，以产生检测到的光子的脉冲。在接收机上存在光子检测的可能概率，并且控制器（370,380,390; 365,470,475,380,390; 570,580,590,390）控制接收机的光子检测概率，基于光照水平。通过根据光级控制检测概率，接收机可以具有增加的动态范围，并且不需要使用光学部件的费用。即使在检测到非常弱的信号的同时也可以应用，因为接收机仍然可以处于光子计数模式，同时控制检测概率。光电平可以由接收器本身的输出或由接收器外部的另一个检测器指示。
