초록
In this paper, the automation of sweeping center setting for wavelength swept laser used in SS-OCT has implemented. For 3 regions where the initial FFP-TF pass wavelength can be located, each different DC voltage pattern is applied to FFP-TF. Through its per- formance test to the laser, fast and exact setting to sweeping central wavelength, flat sweeping with ±0.5 dB fluctuation range, and10 mW average optical power were obtained. This shows that the realized automatic setting process can replace an inconvenient manualsetting operation used for current wavelength swept laser. Additionally it cuts costs for optical spectrum analyzer necessary to laser spec- trum monitoring.
