Detection voltage PSD (distance PSD-VCSEL 40 cm) with collimation

The dataset contains the voltage measured by a PSD (Position Sensing Detector) depending on the x-position of a VCSEL light source (850 nm). The VCSEL is <strong>collimated</strong>, and at a <strong>z-position of 40 cm of the PSD</strong>. The aim is to compare the detection by the PSD of the light spot collimated or not, at different distances. A mean is computed on the data the get one voltage value at the end.

本数据集包含位置传感探测器（Position Sensing Detector）所测得的电压，该电压随850纳米波长的垂直腔面发射激光器（Vertical-Cavity Surface-Emitting Laser）光源的x轴位置变化而变化。该VCSEL为<strong>准直</strong>光束，且与PSD的<strong>轴向间距为40厘米</strong>。本实验的目的为对比不同距离下，PSD对准直与非准直光斑的探测效果。对数据集进行均值计算，最终得到单一组电压值。
