two-dimensional position-sensitive detector psd 两维位置灵敏探测器
psd position sensitive detector 位置敏感探测器
In practical measurement, the positioning precision of position sensitive detector (PSD) is greatly affected by the size and asymmetry of the spot.
在实际测量中，由于光斑具有一定尺寸和不对称性，在很大程度上影响了位置敏感探测器(PSD)的定位精度。
The measurement system is based on facular-orientation theory of position sensitive detector (PSD).
