Application of vibrating mirrors in optical coherence tomography

2024-12-19

Optical Coherence Tomography (OCT) technology is one of the extremely important technical tools in modern optical medicine. In the OCT system, vibrating mirrors play a crucial role. In this paper, we will discuss the application of galvanometer in optical coherence tomography and its importance.

First, the basic principle of optical coherence tomography

Optical coherence tomography technology is based on the principle of optical interference, through the low-coherence interferometer to generate interference signals, tomographic imaging of biological tissues. This technology is widely used in ophthalmology, dermatology and other fields, and is characterized by non-invasive, high resolution and high precision.

Function and role of galvanometer

In OCT system, vibrating mirror is mainly used for scanning biological tissues. It can complete precise beam positioning in a very short time to realize rapid scanning and imaging of biological tissues. In addition, the galvanometer can adjust the scanning speed and direction to image different parts and depths of biological tissues. This enables the OCT system to obtain rich biological tissue information, providing powerful support for the diagnosis and treatment of diseases.

Application of vibrating microscope in OCT

In OCT system, the application of vibrating microscope is mainly reflected in the following aspects:

1. Improve the imaging quality: By precisely controlling the positioning and scanning of the light beam, vibrating microscope can improve the imaging quality of OCT system, which makes the details and structure of biological tissues more clear.
2. Realize three-dimensional imaging: Combined with computer technology and image processing technology, vibrating microscope can realize the three-dimensional imaging function of OCT system, which can be used for the diagnosis and treatment of diseases.
