description	Tomography technique was used widely for its visualisation by section ability. The technique that is popularly used in process industry has high efficiency and is able to improve manufacturing sector. Optical tomography can capture images of objects moving in high speed is a convenience and commonly used in process industry particularly in chemical process. Optical tomography system can be embedded with a controlling unit capable of giving instructions in which to operate the optical sensors. The embedded controlling unit helps reduce processing time of data collection and can be conveniently placed in a minimal working space environment.
