Swept source Optical Coherence Tomography for test of camera lens module

摘要

A swept source optical coherence tomography apparatus for inspecting a camera lens module of the present invention includes: a swept source generator for generating a swept source; The first partial light, which is a part of the swept source, is divided and output as the first light and the second light, and an optical path for the light that combines the reference light and the sample light provided from the outside and the second part light which is the other part of the swept source My Carlson interferometer for outputting optical coherence tomography signals according to differences; A reference end unit that receives the first light from the Myculson interferometer and generates reference light; A sample stage for receiving a second light from the myculson interferometer and irradiating a sample and outputting light returned from the sample as sample light; And a digitizer that digitally converts the optical coherence tomography signal to generate and output optical coherence tomography information.
