We have developed a novel laser ray-tracing method to measure aberrations in optical systems. It consists of delivering narrow laser pencils (by a laser scanner), recording the spots that are formed on the image plane (with a CCD camera), and computing the position of each centroid. This approach could be considered an experimental (approximate) implementation of standard numerical ray tracing. Several tests and experiments, including a direct comparison with a Hartmann-Shack wave-front sensor, provided highly satisfactory results that confirmed the validity of the method and revealed potential advantages.
我们开发了一种新颖的激光光线追踪方法来测量光学系统中的像差。它包括发射窄激光束（通过激光扫描仪）、记录在像平面上形成的光斑（用电荷耦合器件相机）以及计算每个质心的位置。这种方法可被视为标准数值光线追踪的实验性（近似）实现。包括与哈特曼-夏克波前传感器直接比较在内的多项测试和实验给出了非常令人满意的结果，证实了该方法的有效性并揭示了潜在优势。
