Abstract:
The invention discloses a digital laser holography-based rapid lens center offset detection device, which relates to the technical field of lens detection and includes a spherical wave emission device, a reticle, a lens to be detected, an image sensor and a computer. The device is simple and stable in structure, and a complex optical receiving system and mechanical scanning are avoided. A detection method is high in efficiency and measurement accuracy, a process is simple, and a lens with an infinitely great focal length may be detected.
