Abstract

A low coherence interferometer imaging system includes an imaging engine generating a reference beam and an object beam, a first beam splitting element, reference ends, a sample end, and optical imaging modules arranged at the sample end. The first beam splitting element is disposed on an optical path of the reference beam and generates sub-reference beams after the reference beam passes through the first beam splitting element. The reflected sub-reference beams and the reflected object beam form interference signals through the imaging engine. The imaging engine generates images after analyzing the interference signals. One optical imaging module is first arranged at the sample end; the remaining optical imaging modules are sequentially arranged at the sample end in an optical-path series manner so that the images exhibit distinct imaging fields of view before and after the optical imaging module is arranged and when arrangement parameters of the imaging engine remain unchanged.
