一种手持式太赫兹探测系统的光学及结构设计*

An optical and structural design of a hand-held Terahertz detection system based on ZEMAX and ProE

摘要:

随着现代安检技术与健康、隐私问题之间的矛盾愈加突出，人们迫切需要高效、便捷、安全的安检技术。 首先介绍太赫兹非成像光谱探测技术的原理，提出适合于安检应用的太赫兹光谱探测系统技术指标，然后基于 ZEMAX 设计出配合该技术指标的光学系统，采用非序列模式对其进行仿真和评价，最后基于 ProE 设计完成了配合上述光学系统的紧凑型探测系统结构，实现了探测系统的手持式应用。

Abstract:

People need efficient, convenient and safe security inspection technology urgently, as the contradiction between modern security inspection technology and health privacy issues becomes more prominent. This article first introduces the principle of terahertz non-imaging spectral detection technology, proposes the technical indicators of the terahertz spectral detection system suitable for security applications, and then designs an optical system based on ZEMAX that matches the technical indicators, and uses non-sequential mode to simulate and Evaluation, finally based on ProE, completed the design of the compact detection system structure with the optical system, and realized the handheld application of the detection system.
