Abstract:
1. An optical apparatus, comprising: a light source, for providing an incident light; an optical coupling module, for dividing the incident light into a reference light and a detection light, wherein the detection light is emitted to an object to be detected; a reference light reflection module, for reflecting the reference light from the optical coupling module and rapidly changing an optical path of the reference light by a rotational mechanism; wherein, the optical coupling module also receives a first reflected light generated by the reference light reflection module reflecting the reference light and a second reflected light generated by the object reflecting the detection light and the optical coupling module interferes the first reflected light and the second reflected light to generate a light interference signal; and a data processing module, for receiving and analyzing the light interference signal to obtain an optical detection result related to the object; wherein, the reference light reflection module at least comprises a rotation base, a rotation element, reflection units, and a reflection light source, the rotation base itself can rotate and have multiple degrees of freedom, the reflection units are disposed at different positions on a circumference of the rotation element, and the reflection units have different depths respectively.
