چکیده
We have developed optical coherence tomography system with KTN optical probe for a diagnosis in the orthopedic surgery fields. The present system demonstrates that biological image was measured by using KTN optical scanner for having degree of freedom in sample arm as optical coherence tomography. In addition, the developed optical coherence tomography (OCT) system has shown feasibility for imaging biological tissue in orthopedics. The system was shown to have a resolution 14.2 μm for biological tissue in few mm depths. The sensitivity to be measured is 92.3 dB.

Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases. Furtherm...

متن کاملHigh-Speed Optical Coherence Tomography System Using a 200-kHz Swept Light Source with a KTN Deflector
We demonstrate a high-speed swept-source optical coherence tomography (SS-OCT) system, which is based on a highspeed swept light source and a Mach-Zehnder interferometer with a high-speed photodetector. The light source is an external-cavity laser tuned by a KTN electro-optic deflector, which exhibits a very fast response and large deflection. The scanning wavelength range is almost 80 nm up to...
