标题： Development of an optical photon-counting imager with a monolithic Geiger APD array

摘要： 我们开发了一种基于具有高时间分辨率的光学光子计数成像仪的传感器系统，旨在探测高度时变的天文现象。 该探测器是一种单片式盖革模式雪崩光电二极管阵列，在多像素光子计数器中定制，响应时间为纳秒量级。 本文评估了传感器的基本性能，并验证了增益线性、均匀性和暗计数率低的特点。 我们利用一个数据采集系统（时间分辨率为100微秒）展示了该系统检测闪烁LED周期的能力。 使用一台未冷却的35厘米望远镜观测到了蟹状星云脉冲星，设备检测到的光学脉冲周期与射电星历表的数据一致。 尽管需要对系统进行改进以提高可靠性，但该系统已被证明是探索时域光学天文学的一个有前景的工具。 显示英文摘要

摘要： We have developed a sensor system based on an optical photon-counting imager with high timing resolution, aiming for highly time-variable astronomical phenomena. The detector is a monolithic Geiger-mode avalanche photodiode array customized in a Multi-Pixel Photon Counter with a response time on the order of nanoseconds. This paper evaluates the basic performance of the sensor and confirms the gain linearity, uniformity, and low dark count. We demonstrate the system's ability to detect the period of a flashing LED, using a data acquisition system developed to obtain the light curve with a time bin of 100 microseconds. The Crab pulsar was observed using a 35-cm telescope without cooling, and the equipment detected optical pulses with a period consistent with the data from the radio ephemeris. Although improvements to the system will be necessary for more reliability, the system has been proven to be a promising device for exploring the time-domain optical astronomy.
