Abstract

Optical tomography technique has been developing rapidly for various applications particularly in medicals. This technique is considerably interesting due to some safety and low cost source and components, respectively such of use of commercialized an infrared Light Emitting Diode (LEDs) and a photodetector. In this research work, the early test has been carried out to the non-invasive objects of the phantom immersed in the liquid filed in the cylinder. These phantoms were placed between a light source of infrared LED and a detector in the home-made tomography apparatus. From the measurement, the image reconstruction was carried out and then followed by a filtered back projection method. From this, the 2D image of phantoms was successfully observed as distinguishable objects. This result was potentially to be used for medical applications which has advantages of low cost and simple in operation.

Keywords : optical tomography, low cost, infrared LEDs, non-invasive detection.
