Appropriate determination of a mode ratio in collimated light in a double mode is realizable. A light intensity distribution acquisition unit acquires a light intensity distribution of collimated light containing a basic mode component and a primary mode component. A determination processing unit determines a mode ratio in reference to a slope of a curve that is included in the light intensity distribution on a side where a peak value of light intensity is present with respect to a center positioned at an optical axis of the collimated light and that is located at a portion corresponding to an increase in distances from a distance of the peak value. Appropriate determination of a mode ratio in collimated light in a double mode is achievable, and out-of-specification products are eliminable without use of an expensive part. Accordingly, sufficient communication quality of an optical communication system is guaranteed.
