【Abstract】 Based on the working principle of the OCT system, the theoretical analysis on several longitudinal scanning measures, including piezoelectric transition (PZT) scanning, rotating mirror array scanning, femto-laser scanning and manufactured cam wheel transmission of OCT system were made. The experimental study on cam wheel transmission was conducted. The merits of these scanning methods and their demerits were compared and the improvement of longitudinal resolution of these scanning manners was discussed.更多还原
