为了实现对凹凸透镜焦距的精准测量，采用彩色数字全息方法进行理论分析和实验验证，取得了与标称值相差1％的数据结果。结果表明，采用数字全息干涉测量方法是可靠的，可以获得与用透镜标称值重构相同的效果。该研究对数字全息波前的重建有帮助。

In order to measure the focal length of a concave and convex lens accurately , theoretical analysis and experimental verification were carried out based on the color digital holographic method , and the measurement difference relative to the nominal value was 1%.The results indicate the digital holographic interferometry is reliable and the same effect as that of lens nominal value reconstruction can be obtained .The result is helpful for digital holographic wavefront reconstruction .
