Inspection system, inspection device, and inspecting method

An inspection device configured to inspect a composite material member formed of a composite material which has a main surface and an intersection surface which intersects the main surface,

• the inspection device comprising:
• a main body part;
• an ultrasonic probe connected with the main body part and brought into contact with the main surface;
• and
• an optical sensor part connected with the main body part to be movable to the first direction,
• wherein the ultrasonic probe is configured to output an ultrasonic wave to the main surface of the composite material, receive a reflection wave generated by reflecting the ultrasonic wave by the composite material, and output a first output signal corresponding to the reflection wave, and
• wherein the optical sensor part is configured to output sensor light to a second direction orthogonal to the first direction, receive the reflection light generated by reflecting the sensor light on the intersection surface, and output a second output signal corresponding to the reflection light.

An inspecting method of inspecting a composite material member which has a main surface and an intersection surface intersecting the main surface, comprising:

• (A) bringing an ultrasonic probe into contact with the main surface to output an ultrasonic wave from the ultrasonic probe to the main surface;
• (B) receiving a reflection wave generated by reflecting the ultrasonic wave by the composite material member;
• (C) outputting a sensor light to a second direction orthogonal to a first direction while moving the optical sensor to the first direction along the intersection surface;
• (D) receiving a reflection light generated by reflecting the sensor light on the intersection surface;
• and
• (E) outputting a measurement result acquired based on the reflection wave and the reflection light.
