A self-scanned photodiode array was fiber-optically coupled to an ITT proximity-focused image intensifier tube. It was determined that a single photoelectron event produces 3.4 x 10(4) charge carriers in a photodiode. This charge is only a factor of 2.8 above the rms noise level of the preamplifier used in the tests, but standard charge-sensitive techniques are at least a factor of 12 better. The image tube and photodiode array combination can be packaged in a disk 5.1 cm in diameter and 2.6 cm thick.
一个自扫描光电二极管阵列通过光纤耦合到一个ITT近贴聚焦像增强管。经测定，单个光电子事件在光电二极管中产生3.4×10⁴个电荷载流子。该电荷仅比测试中使用的前置放大器的均方根噪声电平高2.8倍，但标准的电荷灵敏技术至少要好12倍。像管和光电二极管阵列的组合可以封装在一个直径5.1厘米、厚2.6厘米的圆盘内。
