摘要	A method and an apparatus for compensating for wavelength drift are disclosed. The method includes: generating, by a burst control circuit, a burst bias current; sending, by the burst control circuit, the burst bias current to a light emitting part and a trigger; converting, by the trigger, the received burst bias current into burst DA data; sending, by the trigger, the burst DA data to a synthesizer circuit; receiving, by the synthesizer circuit, the burst DA data sent by the trigger and the calibrated DA data sent by the MCU respectively; synthesizing, by the synthesizer circuit, the burst DA data and the calibrated DA data to obtain a synthesized signal; and sending, by the synthesizer circuit, the synthesized signal to a temperature control part.
其他摘要	公开了一种用于补偿波长漂移的方法和装置。该方法包括：通过突发控制电路产生突发偏置电流;通过突发控制电路将突发偏置电流发送到发光部分和触发器;通过触发将接收的突发偏置电流转换为突发DA数据;通过触发器将突发DA数据发送到合成器电路;所述合成器电路分别接收所述触发器发送的突发DA数据和所述MCU发送的校准DA数据;合成器电路合成突发DA数据和校准后的DA数据，得到合成信号;合成器电路将合成信号发送到温度控制部分。
