With the rapid development of science and technology and modern medicine, the application of optical technology in biomedicine has become increasingly important. Optical technology not only improves the accuracy and portability of doctors to diagnose diseases, but also promotes biomedical development, life science research, and clinical applications. Now, it has become an integral part of modern medicine.

Biooptical imaging technology is an important means in the field of biomedical research. Its role is increasingly prominent. By using high-precision optical technology, doctors can obtain high-quality biological images of humans or animals without damaging biological tissue. This provides a powerful tool for studying the true workings and structure of biological systems, as well as identifying and quantifying the effects of disease. For example, optical coherence tomography (OCT) can be used in ophthalmology to diagnose various eye diseases, and can also be used in cardiovascular imaging to achieve high-resolution imaging of living tissues, providing a very valuable means for diagnosis and treatment of diseases. Endoscopy technology transmits the image of the whole endoscope microscope to the observation instrument through optical imaging technology, which can observe the condition of the organ in real time, and provide important information for the clinician to diagnose, treat and operate.
