Optical syntropic fault detection device and operating method thereof

Abstract

The invention provides an optical syntropic fault detection device, which comprises a light source, an optical coupling module and an optical path difference generating module. The light source is used for emitting syntropic light. The optical coupling module is used for dividing the syntropic light into first incident light and second incident light. The first incident light is shot to an objectto be tested so as to generate reflected light; the second incident light is shot to the optical path difference generating module; and the optical path difference generating module generates second reflected light according to the second incident light in a mode of changing transmission / reflection characters of at least one optical element, so that an optical path difference exists between the second reflected light and the first reflected light. The invention also provides an operating method of the optical syntropic fault detection device.

Description

technical field [0001] The present invention relates to optical detection, in particular to an optical coherence tomography detection device capable of providing effects of optical path difference and optical frequency change without using a mechanical structure and an operation method thereof. Background technique [0002] In recent years, with the continuous advancement of optical detection technology, optical image scanning technology provides a non-invasive method to understand the structure and composition of the target tissue. Due to its fast and non-invasive characteristics, this type of technology has considerable Wide range of applications, especially in medical diagnosis. When light is incident into the tissue structure, the absorption and scattering properties of the light will also change with the change of the medium at different depths. Optical image scanning is to use various optical methods to obtain the information carried by the inside of the tissue and the...
