Origin

The optical fiber micro-crack tester is a high-precision reflection distribution measurement device based on Time-Domain Optical Coherence Tomography (TD-OCT) technology. It adopts the classic Michelson interferometer structure, splitting the light output from a low-coherence light source into two paths through a coupler, which are respectively introduced into the device under test (DUT) and a movable mirror. When the optical path difference between the two paths is zero, the reflected light interferes; the interference light intensity is proportional to the optical return loss of the DUT, thereby precisely obtaining the return loss value at that position. By continuously moving the mirror and recording the interference signal, the instrument can reconstruct the distribution curve of the optical return loss inside the DUT versus position, achieving precise localization and quantitative analysis of tiny defects.
