To provide a high-speed computerized tomography method capable of observing and measuring three-dimensional information and its time change in a very short time, and a device therefor.
A neutron beam 2 is irradiated to an object substance 3 while rotating the object substance 3 at a high-speed by the use of a motor 17 for rotation. The neutron beam 2 irradiated to the object substance 3 is passed through the object substance 3, and then the beam is converted to light by a neutron-light converter 4; the light converted is passed through a mirror 5, a lens 14, and an image-intensity amplifier 15 that are located to reflect and transmit the light behind this neutron-light converter 4; and the light reflected and transmitted is recorded as a continuous image by a CMOS type element 16 in a high-speed video camera. The recorded image is transferred to a computer 8, and three-dimensional calculation is performed with a CT calculating computer 12. Thus, three-dimensional information averaged in a short time is obtained. Also, time change information of the three-dimensional information can be obtained by continuously calculating this three-dimensional information averaged in time series.
