Abstract: A non-destructive inspection system 1 includes a neutron detecting unit 4 and an arithmetic unit 60. The neutron detecting unit 4 includes a collimator 30 and a neutron detector 20 integrated together. The collimator 30 has a wall defining a through passage P. The wall is made from a material that absorbs neutrons produced via an inspection object. The neutron detector 20 is capable of detecting neutrons that have passed through the collimator 30. The arithmetic unit 60 generates information on a position and composition of the inspection object, based on information on the neutrons detected by the neutron detector 20, positional information indicating the position of the neutron detecting unit 4, and posture information indicating the posture of the neutron detecting unit 4. The positional information and the posture information are detected by a position and posture detecting unit 5.

Abstract: An ophthalmic apparatus according to an embodiment includes a fixation system, a data acquisition device, analyzing circuitry, and controlling circuitry. The fixation system projects fixation light onto a subject's eye. The data acquisition device acquires data by applying optical coherence tomography scanning to the subject's eye onto which the fixation light is being projected. The analyzing circuitry analyzes the data to specify the position of a predetermined site of the subject's eye. The controlling circuitry controls at least one of the fixation system and the data acquisition device based on the positional relationship between the position of the predetermined site specified by the analyzing circuitry and a scan area by the data acquisition device.
