提出将全息干涉条纹和相移技术用于三维面形测量 ,首先利用相移进行位相解调 ,得到各点的包裹相位分布 ,再利用投影条纹最小二乘法得到的高度信息对位相进行去包裹处理 ,从而得到具有较高精度的位相测量和相应的三维面形测量结果 Proposed to use the holographic interference fringes and phase shift techniques for the three-dimensional surface measurement, the first phase shift using phase demodulation to get the phase distribution of the various points, and then use the projection of the least squares information obtained by the height of the information on the phase wrapped to deal with , Resulting in higher accuracy of the phase measurement and the corresponding three-dimensional surface measurement results
