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

Claim 11:
12. A program product for 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 program includes instructions of a controller for 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.
