Business Field
Medical Diagnosis
The Optical Coherence Tomography (OCT) device for medical diagnosis is a high-resolution imaging technology based on near-infrared light, which is mainly used for non-invasive and radiation-free in vivo tissue tomography. By detecting light reflection signals, it generates cross-sectional images with micron-level resolution. Widely applied in ophthalmology, dermatology and other fields, it enables real-time observation of tissue microstructure and assists in the early diagnosis of diseases.
Industrial Inspection
The Optical Coherence Tomography (OCT) device for industrial inspection is specially designed for the non-destructive testing of the internal microstructure of materials or components. By emitting low-coherence light beams and analyzing the reflected signals, it can generate real-time cross-sectional or three-dimensional images of samples with micron-level resolution. It is suitable for the internal defect detection, layer thickness measurement and quality control of transparent/translucent materials or precision components.

Principles of OCT Technology
OCT leverages the principle of optical low-coherence interferometry. It splits the light emitted by a broadband light source into two beams: one beam irradiates the measured object (sample light), which undergoes backscattering after entering the object. The other beam acts as reference light, which is reflected back by a fixed reference mirror. The two beams recombine at the beam splitter to generate an interference signal. An effective interference signal is only formed when the optical path difference between the two arms falls within the coherence length of the light source. By measuring the variation of the interference signal with the optical path difference, information about different depths inside the sample can be obtained, and then a 2D or 3D structural image of the sample can be reconstructed.
