摘　　要：Swept source optical coherence tomography(SS-OCT)is a new noninvasive technique for assessing tissue.Although it hasadvantages,such as being label-free,noninvasive,and with high resolution,it also has drawbacks:there has been no indepth research into identifying the driving of swept source.Based on preliminary research,we demonstrate a novel drivingmodulation method of a fiber Fabry–Perot tunable filter ranging phase adjustable as a tool for making bandwidth compensation of a swept laser source.This novel method is analyzed in detail;a swept laser source with a sweep rate of100.5 kHz over a range of 152.25 nm and at a center wavelength of 1335.45 nm is demonstrated.
