Abstract: An optical system comprises a first optical path configured to supply a first light with a first range of wavelengths; a second optical path configured to supply a second light with a second range of wavelengths shorter than the first range of wavelengths; a third optical path configured to supply a third light with a third range of wavelengths shorter than the second range of wavelengths; an optical I/O unit configured to emit the first light, the second light and the third light to a target and acquire a light from the target; a reference unit configured to split off a reference light from the third light; and a detector that includes a range of detection wavelengths shared with a CARS light and an interference light.

Abstract: A system including a signal obtaining module and a controller is provided. The signal obtaining module includes: a receiver to which an emission light generated in the target by an excitation light is input; a receiving optical path that guides the emission light and a residual light, which is at least a part of the excitation light propagated forward, coaxially between the target and the receiver; a separator that separates the residual light from the receiving optical path to be routed to an image sensor; and an actuator for controlling an optical relative position between the target and the receiver. The controller includes a module that controls the actuator to maintain an optical alignment.

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.
