Position Sensitive Detector (PSD) is a device utilizing the lateral photoelectric that produced by the non-uniform illumination of a rectifying semiconductor junction. The linear requirement, spectral responds, position detection error of 1D PSD were presented in this paper. All these studied works are the theoretical basis for designing and fabrication PSD with excellent performance. The experimental results show that the rms non-linearity and the typcial position error are 0.1% of full length (8 mm) and ±5μm.
