摘要
太赫兹波(THz)是频率介于毫米波与红外光之间的辐射。本文设计了一种太赫兹波混合器,通过透镜将太赫兹波聚焦到124×124热释电列阵相机,并对其所生成的图像进行计算机优化处理,同时,对有无透镜情况下的电场模值分布进行了仿真模拟比较。
THz wave is a kind of radiation whose frequency is between millimeter wave and infrared.This paper presents a THz mixer,which focuses the THz wave to the 124×124 pyroelectric array cameras through lens,and then the generated images are enhanced by means of image processing and analysis.In the end,the comparison of distribution of the electric field modulus with and without lens is presented through simulations.
