Abstract: A system for measurement is provided. The system includes a first optical path configured to supply first light pulses with a first range of wavelengths; a second optical path configured to supply second light pulses with a second range of wavelengths shorter than the first range of wavelengths; an optical I/O unit configured to emit the first light pulses and the second light pulses to a target and acquire a light from the target to detect CARS light pluses from the target by a detector; and a first phase modulating unit configured to vary phase differences between the first light pulses and the second light pulses as the first light pulses and the second light pulses are emitted via the optical I/O unit.
