We made performance evaluations of InGaAs near-infrared image sensor which are produced by Hamamatsu Photonics Co. Ltd. (HPK) under cold environment in collaboration with HPK. We tested a 64 x 64 pixels with 50 micron pitch array and 128 x 128 pixels with 20 micron pitch array sensors. Before testing the sensors, we developed a vacuum-cooling dewar which is dedicated to performance evaluation of optical-infrared image sensors and a sensor readout system. The evaluation system we developed is very versatile to be used for testing various types of optical-infrared image sensors. We found that 128 x 128 pixel sensor has a quantum efficiency of 80% in a wavelength region from 0.9 microns to 1.6 microns with a readout noise of 160 electrons. We fed back the results of our performance evaluation tests to the manufacturers, and define a direction to next development of new infrared image sensors.

我们与HPK合作，对日本滨松光电株式会社（HPK）生产的InGaAs近红外图像传感器进行了冷环境下的性能评估。我们测试了具有50微米间距阵列的64 x 64像素传感器和具有20微米间距阵列传感器的128 x 128像素传感器。在对传感器进行测试之前，我们研制了一台用于红外光学图像传感器性能评估的真空冷却杜瓦瓶和传感器读出系统。我们开发的评估系统是非常通用的，可用于测试各种类型的光学红外图像传感器。我们发现，128 × 128像素传感器在0.9微米至1.6微米的波长范围内具有80%的量子效率，读出噪声为160个电子。我们将性能评估测试的结果反馈给制造商，并为下一步开发新的红外图像传感器确定了方向。
