当前,在科学技术领域中,盛行着光电倍增管,硅光二极管和硒光电池等光电传感器。但是,它们具有一个共同的弱点,即受光面灵敏度不均匀,例如,光电倍增管的不均匀性大约在0.05/mm 左右,因此,如果把由光源来的 At present, in the field of science and technology, the prevalence of photomultiplier tube, silicon photodiode and selenium photoelectric sensors. However, they have a common weakness that the sensitivity of the light receiving surface is not uniform. For example, the non-uniformity of the photomultiplier tube is about 0.05 / mm. Therefore, if the light source
