摘　　要：锥光全息非接触式测量系统的相位测量法可以有效降低光源波动及光学噪声的影响,而增量式相位测量又可以提高绝对式测量的测量精度。为此,本文采用增量式相位测量法进行系统测量实验,用双频激光标定标准输入量,并采用遗传算法优化系统的输出特性曲线参数。实验结果表明,遗传算法大大降低了特性曲线求解的复杂性,保证快速收敛的同时避免了局部寻优的问题,对提高锥光全息测量系统分辨力具有重要意义。Phase Measurement of the conoscopoc hologram can restrain laser ？ uctuation and optic noise effi ciently, and incremental phase measurement can improve the precision of absolute phase measurement. So the measurement experiment of the system was built with incremental phase measurement, the standard input was calculated by double frequency laser, and output character parameters of the system were optimized by Genetic Algorithm. Experiments results showed that GA can deduce complexity of solving characteristic curve, can ensure fast convergence and avoid Local optimization. It is important to improve the accuracy of system.
