“…one orthogonal with two rectilinear projections and combination of two orthogonal with two rectilinear projections (Sallehuddin 2000). This latter arrangement can provide sufficient information to minimize ambiguous effects arising during cross-sectional image detection compared to the previous three projections.…”

The ASM Science Journal (ASM Sc. J.) is intended to be one of the primary vehicles of the Academy of Sciences Malaysiato stimulate and nurture excellence in science and technology for the development of the nation and for the benefit ofmankind. Its purpose is also to widely disseminate significant research developments and deliberate on R&D strategiesand policies. It will further provide a major opportunity for showcasing the effectiveness of scientific and technical effortsand increasing the efficiency of management of research and development which is linked with the ability to communicateinformation about current research efforts and the results of past work. This journal will pay attention to the importanceof scientific and technical endeavour and contribute to the better understanding of problems of science and technologythrough its regular publication and wide circulation, thus promoting cooperation and exchange of views among the sciencecommunity worldwide. All these objectives are fully in line with the aims and objectives of the Academy.In this maiden issue, there are contributions from many fields covering both fundamental and applied research: medicine,engineering, chemistry, electronics, mechanics and physics. Our future plan is to gear one issue a year towards a particulartheme. The papers in that issue will address current and impending issues, and the demands and needs of the scientificcommunity and society pertaining to the selected theme.It is hoped that this varied, vital and vigorous exchange of scientific information that the Journal provides will assist inbetter understanding the various forces and factors that affect the progress of humanity and safeguard its survival. TheAcademy of Sciences Malaysia, therefore, in earnestly discharging its responsibility, proudly associates itself with thisJournal in striving to promote an international exchange of scientific information.

& Optical fiber sensors have been applied for process tomography of gas=liquid and gas=solid two-phase flow systems, such as hydraulic flow rig, pneumatic conveying, fluidized beds, and flame combustion. Optical fiber process tomography has the general characteristics of non-invasiveness, high accuracy, and security. For optical fiber image reconstruction of rate and accuracy, a large number of scholars have been active in this area in recent years. This article systematically and thoroughly describes optical fiber sensors in process tomography applications, for instance, hardware components, optical structure, and the reconstruction algorithm. With the research going on, the technology of optical fiber sensors will be more significant in process tomography and other fields.

“…There are µ sensor units distributed around the circle and each unit emits or receives ρ optical rays. The relationship of the four parameters are described as: (4) where 4<m<12, m′ ≤ 3 and m′ /m<1/2. The relative image-reconstructed resolution, χ t , is defined as the reciprocal value of the pixel number in the measured region, which is expressed as:…”

Multi-phase flows exist in industry extensively. The flows of the media produce all kinds of processes and change them constantly and profoundly, which has a great influence on product quality, cost and safety to make the process monitoring and control very important. Optical fiber process tomography (OFPT), however, is a new method to realize the detection of the flow process and has gained much attention in recent years. Compared with other tomography technologies such as capacitance, microwave and impedance ones, OFPT use optical fiber sensors (OFS) as core elements to make it small, safe, free of electromagnetic interference and have high sensitivity in low-density medium case. Moreover, OFPT can detect the media information of the whole investigated plane simultaneously, which is difficult for the ordinary sensors. OFPT has many improvements in recent years both in its structure and design theory.In this paper, a sort of the novel OFPT structures is put forward. Compared with the original one, they have higher image-reconstructed resolution (the relative resolutions are 1.04%, 0.71%, 0.52%, 0.4%, 0.31% and 0.25%, respectively) and can also be used in the cylindrical space with circular planes owing to the circular symmetry.
