Assignee: ATONARP INC.
Field: Measurement (Instruments)
Classification: CPC G  A | IPC A  G

Claim 7:
8. A method of controlling a system comprising:
an input optical path configured to input an excitation light to a target to generate an emission light containing information related to components contained in the target using a nonlinear optical method, and
a signal obtaining module for obtaining signals containing the information related to the components contained in a target from the emission light propagated forward through the target,
wherein the signal obtaining module includes:
a detector to which the emission light is input for generating the signals from the emission light;
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 through the target with the emission light, coaxially between the target and the detector;
a separator that separates the residual light from the receiving optical path and directs the residual light to an image sensor;
an optical path that guides the separated residual light to the image sensor; and
an actuator for controlling an optical relative position between the target and the detector, and
the method includes controlling the actuator to maintain an optical alignment between the target and the detector that detects the emission light filtered by the separator according to a detection result of the separated residual light on the image sensor.
