This research discusses an application of Couple-Charge Device (CCD) linear sensor and laser diode in an optical tomography (OPT) system. Tomography is a system that could capture a cross-sectional image based on sensor data scattered across the periphery of the examining device in the non-invasive and non-intrusive framework. This project focuses on quantifying the level of object transparency based on CCD and mathematical modelling assessment. The objective of this project is to investigate the light refraction, reflection and absorption effect on object transparency. The study will include a discussion on the light parameters and its mathematical expression. The voltage output measured by CCD defines the degree of intensity of light obtained after penetrating through different object transparency. In conclusion, this research has successfully proved the potential of CCD in OPT configuration to detect different size diameters of a targeted transparent object, which is an air bubble in non-flowing crystal-clear liquid.

Several gemmology technologies, including loupes, microscopes, and dichroscopes, are currently utilised to assist gemstone traders in evaluating rubies. These tools, on the other hand, rely heavily on human vision for pictorial assessment. There are no standardized tools for determining ruby stone grading, other from those that rely on human vision, which can lead to errors. Gemmologists, stakeholders in the precious stone and manufacturing industries, as well as dental applications, would benefit from a standardized quantitative grading valuation of ruby stones. Extensive research is required to analyse the light characteristics of rubies. This paper presents a potential research overview of the Charge-Coupled Device (CCD) linear sensor to inspect the grading value of ruby stone based on its light characteristic. This research delves deeper into the relevant light properties of rubies for grading purposes. Numerous types of gemmological instruments are used for grading and appraising rubies, as well as their applications, are discussed in this paper. A standardized approach for quantitative grading valuation of ruby stones utilising a Charge-Coupled Device (CCD) linear sensor is offered due to the limits of current techniques and the strong demand for superior quality in the high-valued stone sectors.
