Penyelidikan ini menunjukkan konfigurasi sensor tomografi optik dengan penggunaan pemancar inframerah dan foto transistor. Geometri unjuran sensor adalah berdasarkan kombinasi dua unjuran oktagon dan dua unjuran garis lurus tatasusunan. Sebuah perlengkapan direka untuk memegang keseluruhan pasangan pemancar–penerima secara selari. Pemilihan foto transistor juga dijelaskan supaya pembangunan sensor tomografi adalah bebas dari bacaan yang tidak diingini daripada persekitaran sekeliling. Penulisan ini juga menerangkan perkara–perkara yang perlu dipertimbangkan untuk pembangunan sensor tomografi optikal. Kata kunci: Inframerah; tomografi optikal This paper represents the configuration of optical tomography sensor by using infrared emitter and phototransistor. The projection geometry of the sensor is based on the combination of two orthogonal and two rectilinear projections arrays. A fixture is designed for holding all emitter–receiver pairs in parallel. Selection of phototransistor is explained so that the tomography sensor developed is free of noise cause by surrounding environment. This paper describes all points to be considered when design an optical tomography sensor. Key words: Infrared; optical tomographyDownloads
