An optical computed tomography（optical CT）is an imaging device that acquires a tomographic image by using visible light or near infrared light. In our previous study, optical CT using visible light was developed. However, the developed system was applicable to a transparent or small object. In this study, we focused on near-infrared light, and we conducted development and basic evaluation of an experimental system of optical CT using a near-infrared light. As for the experimental system, we developed the simple structure system employed near-infrared light source, single-lens reflex camera, and rotational table. In the experiments, we investigated the imaging properties of developed system using three types of samples. Results indicate that our system may be useful to obtain the tomographic image of biological samples.
