本申请提供的一种多波长光声成像方法、驱动系统及实验装置，通过采用一单波长的脉冲激光源激发光声信号；采用一或多个不同波长的连续激光源加热成像目标，以使激发的所述光声信号不同程度的增强，以实现多波长光声成像。本申请中用于激发光声信号的脉冲激光源能够实现脉冲调制和连续调制，适用于两种时域和频域光声成像，且成本低。

To the multi-wavelength photoacoustic imaging method, the driving system and the experimental device, a photoacoustic signal is excited by adopting a single-wavelength pulse laser source. The imaging target is heated by one or more continuous laser sources of different wavelengths, so that the excitation light photoacoustic signal is enhanced to a different degree so as to realize multi-wavelength photoacoustic imaging. The pulse laser source used for exciting the photoacoustic signals can realize pulse modulation and continuous modulation, is suitable for two time domain and frequency domain photoacoustic imaging, and is low in cost.
