OCT is a technology that visualizes the tomographic structure of an object using the coherence of light. It is widely used in the medical field because it can irradiate near-infrared rays and can perform non-invasive and non-contact image. Especially in the field of ophthalmology, it is an indispensable diagnostic device.
The scope of application of OCT is not only for medical applications such as ophthalmology, cardiology, dermatology, and gastroenterology, but also actively researching, developing and commercializing biotechnology in regenerative medicine and industrial fields such as laser welding monitoring.
