光学PT扇束结构权重系数矩阵计算与实现

Calculation and realization of the weight coefficient matrix of fan-beam structure in optical PT

权重系数矩阵是光学过程层析成像(optical process tomography,简称光学PT)技术中非常重要的参数之一,它的传统计算是基于人工测算,其缺点是烦琐、且极其耗时。因此,本文利用Visual C++语言实现了光学过程层析成像系统扇束阵列传感器结构权重系数矩阵的即时计算。为光学敏感场灵敏度分布的计算、图像重建仿真以及光学PT系统的实现节省了时间,缩短了研究周期。

The weight coefficient matrix is one of the most important parameters for optical process tomography technology, which was traditionally calculated with hands and costed too much time. Therefore, this paper introduces the design on program for calculating the weight coefficient matrix of fan-beam structure sensors in optical process tomography system using Visual C++. It establishes the base of the calculation on sensitivity distribution of optical sense field and the simulation of image reconstruction together with the realization of the optical PT system.
