Paper Abstract
In the near-infrared-ray computed tomography (NIR-CT) scanner, NIR rays are produced from a light-emitting diode
(LED) and detected using an NIR phototransistor (PT). The wavelengths of the LED peak intensity and the PT high
sensitivity in the data table are both 940 nm. The photocurrents flowing through the PTR are converted into voltages
using an emitter-follower circuit, and the output voltages are sent to a personal computer through an analog-digital
converter. The NIR projection curves for tomography are obtained by repeated linear scans and rotations of the object,
and the scanning is conducted in both directions of its movement.
