“…In the field of process tomography, researches conducted by Ibrahim et al (2002), Yan et al (2005), Md Yunus (2005) and Abdul Rahim et al (2005) utilized optical fibre for imaging and identifiying various flow patterns and boundaries. In another research area, Garcia et al (2007), Bilro et al (2010) and Prerana et al (2012) proposed the design of a turbidimeter using optical fibre.…”

Purpose – This paper aims to present a review of the design and development of the turbidimeter for measuring the turbidity level in water. Monitoring the turbidity level of water is important because it is related to public health. Design/methodology/approach – A precise and reliable turbidimeter can provide vital data that reveals the water condition level. Several turbidimeter units are discussed briefly. Three types of turbidimeter design – single beam, ratio and modulated four beams – are elaborated with some illustrations of the design concept. Various improvements and innovations for upgrading turbidimeter design are also discussed. Findings – This paper elaborated on a new method of estimating the water turbidity level in water samples using an optical tomography system based on the independent component analysis method. The results showed that a tomography-based turbidimeter can measure slight changes in the level of turbidity when the volume of contaminants is changed slightly. The turbidimeter can also provide a profile of the distribution of the turbidity in the water sample. Originality/value – A turbidimeter based on the optical tomography concept can be a valuable tool in determining the level of pollution in rivers, sea, etc.

“…Fan beam projection is preferable for optical tomography since it can offer more number of measurement from the measurements transducer [15]. The fan beam projection is not concentrating to a straight line but focus on transmission angle [16]. The transmission angle can be known by looking to the data sheet of the transmitter where usually the angle value is notified.…”

Optical Tomography (OT) is a form of computed tomography using a digital model of the volume of an object by reconstructing an image of the light transmitted and scattered by the object. OT is used mostly as a form of research in medical imaging. OT depends on the reference object being at least partially light transmitting or translucent, so it works best on soft tissue, such as breast and brain tissue. Optical Coherence Tomography (OCT) is a new technology for performing high-resolution cross-sectional imaging. OCT is similar to ultrasound imaging, but uses different types of light instead of sound. OCT can provide cross-sectional images of tissue structure on the micrometer scale and in real time. OCT serves as a kind of optical biopsy and is used as a medical diagnostic imaging technology because, unlike conventional histopathology, it does not require the removal and processing of tissue specimens for microscopic examination. The study was carried out to see how the two types of optical imaging and the use of concepts and components used in the system. The light source is used to show different levels of penetration and resolution for both methods is used. The use of an interferometer in optical imaging applications is discussed along with examples of commonly used methods. The optical imaging method contributes significantly to the diversity of tomography systems.
