초록
In this paper, the sine-wave and trigger pulse generator with capability of frequency high-resolution and time-variable trigger edge has implemented. It fulfills well the requirements for SS-OCT with frequency resolution of 1 Hz, frequency stability of ≤ ±0.03 Hz and time-variable trigger edge. Through its performance test applied to the wavelength swept laser, 90nm, sweeping range and 10 mW average optical power were obtained. This showes that the realized generator can replace the commercial high cost and high performance signal generators employed by current SS-OCT systems.
