Pembangunan bahagian hadapan adalah penting di dalam tomografi optikal. Ia memberikan pandangan pertama tentang bagaimana kebolehpercayaan sistem tomografi kepada pengukurannya. Oleh itu, litar penghantar dan penerima mesti dibina berhati-hati dengan analisis yang baik untuk setiap pemilihan unit komponennya. Kertas kerja ini akan menunjukkan kesan pembangunan litar kepada mutu kelinearannya. Tujuan kertas kerja ini adalah untuk membina litar penghantar dan penerima untuk aplikasi tomografi optikal. Ia dilakukan dengan mendapatkan unit voltan pada bahagian penerima setelah bertindak balas terhadap kewujudan penghalang yang mengganggu laluan cahaya di antara penghantar dan penerima. Reka bentuk eksperimen ini menggunakan penghalang dari jenis yang sama dengan perbezaan saiz di antara 0.5 hingga 3 mm. Daripada keputusan ia menunjukkan lebih besar objek, nilai bagi kehilangan voltan juga akan meningkat. Ini menunjukkan hubungan yang linear di antara kedua-dua parameter. Kata kunci: Tomografi optikal penghantar; penerima; litar; kelinearan Front end development is crucial in optical tomography. It gives the first impression on how reliable the tomography system towards its measurement. Therefore, transmitter and receiver circuit must be developed carefully with good analysis for each selection of the component units. This paper will show the effect of circuit development towards linearity performance. The aim of this paper is to construct a transmitter and receiver circuit for optical tomography application. This is done by capturing a voltage unit at the receiver side in response to the existence of obstacle that interrupt the light path between transmitter and receiver. The experiment design uses a same type of obstacle with different sizes between 0.5 until 3mm. From the result it shows the bigger the object the voltage loss value also increasing. This shows a linear relation between both parameters. Key words: Optical tomography; transmitter; receiver; circuit; linearityDownloads
