Abstract
A novel optical coherence tomography system without any moving part.,, for depth scanning was proposed and demonstrated. It was accomplished using two optical frequency comb generators, as broad-band spectrum generators, inst ead of moving part,, for depth scanning. A high scanning speed of more than 12,5 km/s and also a high repetition rate of 500 kHz were achieved in a lo ng scan range of 25 mm. The resolution was about 100 mum.
