Classification: CPC A  G | IPC A  G

Claim 13:
14. A method comprising:
emitting a first light with a first range of wavelengths and a second light with a second range of wavelengths shorter than the first range of wavelengths through an optical I/O path that is configured to output the first light and the second light to a target and acquire a light from the target;
detecting a CARS light, by a detector, generated by at least the first light and the second light at the target;
emitting a third light with a third range of wavelengths shorter than the second range of wavelengths through the optical I/O path to the target, the third range of wavelengths being at least partly overlapping a range of wavelengths of the CARS light; and
detecting an interference light by the detector, wherein the interference light is generated by a reference light split off from the third light and a reflected light from the target, and the detector includes a range of detection wavelengths shared with the CARS light and the interference light.
