Optical tomography sensor configuration using two orthogonal and two rectilinear projection arrays

3D Reconstruction of Slug Flow in Mini-Channels with a Simple and Low-Cost Optical Sensor

“…Ruzairi et al presented an optical tomography sensor, which consisted of two orthogonal and two rectilinear optical arrays. They further used a hybrid image reconstruction algorithm to reconstruct 2D images [7]. For better resolution, Schleicher et al proposed a fast optical tomography sensor with 256 light emitters and 32 light receivers.…”

“…Especially with the fast development of semiconductor technology and elaborate processing, integrated and miniature optical sensors provide a promising approach for 2D/3D reconstruction in restricted space. However, corresponding research is insufficient, and most of the reported optical methods focus on conventional channels [7,9,11,12]. The present work presents a new approach for 3D visualization of GLF in mini-channels based on a new optical sensor with a horizontal and vertical photodiode array.…”

Optical Tomography System Using Charge-Coupled Device for Transparent Object Detection

“…The optical tomography system (OPT) is one of the famous tomography methods that have been used in the medical and process industries. The OPT system is considered as a hard-field sensor because the sensing field is based on the measurement of the attenuation or absorption of radiation [1,5]. Generally, the main concept of OPT is to analyse the structure and composition of objects by examining the waves or radiation intensity after crossing the measured object [2,7].…”
