<p>A timing, at which a CCD camera driving circuit (7) switches an operation state of an interline-type CCD camera (5) from a charge sweeping-out operation state to an exposure operation state, is delayed behind a time, when a light (R) to be measured is emitted from a sample (9), to reduce noise which is produced in the interline-type CCD camera (5) by a neutron beam emitted from the sample (9) together with the light (R) to be measured.</p> |
