Schematic of tunable-color OR-PAM system. The purple and the blue dashed lines indicate the laser spectra, as well as the real light colors before and after PM-SMF optical fiber, respectively. HWP: half-wave plate; VBA: variable beam splitter/attenuator; FC: fiber coupler; PM-SMF: polarization-maintaining single-mode fiber; BPF: bandpass filter; OL: objective lens; CL: corrective lens; GS: glass slab; PMB: plastic membrane; SFT: spherically focused transducer; OABC: optical-acoustic beam combiner; DAQ: data acquisition.
