首先分析了半导体光电位置敏感器件(PSD)的工作过程.利用连续发射的激光光源和半导体光电位置敏感器件,设计了一种三维非接触高精度的光学测量系统.该系统根据定位于被测量物体上直角坐标系的格线,生成该物体的外形,从而用于不规则三维物体多种参数的测量和诊断.该系统使用了光学装置,特别适用于不规则形状尤其是边缘形状的图形的精确测量和探测,测量出的数据对于研究和诊断皮肤损伤的形态、特征和类型之间的关系等有很高的价值,应用前景非常广阔.

The working process of the semiconductor photoelectric position sensitive device is analyzed. Using the continuous sending laser light source and semiconductor photoelectric position sensitive device, a high accurate tri-dimensional non-contact optical measurement system is designed. With the gridlines of the rectangular coordinate system located on the object being measured, the outline of the object is produced by this system, then it is applied to the measurement and diagnosis of multi-parameter of the irregular tri-dimensional object. Consisting of optical arrangement, this system is suitable for accurate measuring and detecting of the figures with irregular shape especially the edge shape. The tested datum has high value for studying and diagnosing the relationships of the skin lesion's format, character and type. The system will be used widely in the future.
