We have developed and successfully used an integrating two-dimensional silicon diode array vidicon photometer which is exceptionally well suited for use with telescopes. The video signal is read out from the 1-cm silicon target of the vidicon through a current mode preamplifier and then converted to digital form and stored on magnetic tape. The 256 x 256 element frames are recorded at 20,000 eight-bit words/sec. The vidicon tube has a published quantum efficiency ranging from 85% at 0.5 micro to 6% at 1.1 micro and must be cooled to about -65 degrees C to eliminate thermal dark current. The minimum detectable signal in the present system is about 1000 carriers per resolution element, limited by preamplifier and other system noise. The system is used as a single-frame camera. The large dynamic range (>10(3)), linear response, high quantum efficiency over a large spectral region, and low cost of the system make it well suited for digital direct image and spectroscopy as well as for a laboratory digitizer of two-dimensional m terial.
我们已经研制并成功使用了一种集成二维硅二极管阵列光导摄像管光度计，它非常适合与望远镜配合使用。视频信号通过电流模式前置放大器从光导摄像管的1厘米硅靶读出，然后转换为数字形式并存储在磁带上。256×256像素的帧以每秒20,000个八位字节的速度记录。该光导摄像管的公布量子效率在0.5微米时为85%，在1.1微米时为6%，必须冷却到约-65摄氏度以消除热暗电流。当前系统中的最小可检测信号约为每个分辨率元素1000个载流子，受前置放大器和其他系统噪声限制。该系统用作单帧相机。该系统的大动态范围（>10³）、线性响应、在大光谱区域的高量子效率以及低成本，使其非常适合数字直接成像和光谱学，以及作为二维材料的实验室数字化仪。
