Abstract

An analytical review of optical-acoustic detectors (OADs) based on Golay cells for use in the infrared (IR) and THz radiation ranges is given. The history of the discovery and development of the OAD from the first works of Bell, Hayes and Goley and up to the present time is presented. The advantages of the OAD are noted; they consist in constant and high sensitivity in a wide range of the spectrum and the highest detection ability among thermal detectors. The main characteristics of the membranes, the main elements of the OAD, are considered and the physical properties of graphene, the most preferred material for membranes, are analyzed. Three OAD design groups are proposed: single cells with optical information reading and a capacitor-based microphone, selective detectors with gas-filled chambers, and matrix detectors. Estimates are given showing that the use of SLG-graphene membranes makes it possible to create IR and THZ radiation detectors with cells on the order of tens of microns in size and extremely high sensitivity. A new design scheme of matrix THz optical-acoustic detectors with the use of membranes made of hexatrigraphene (C)\({}_{63(6)}\) with record-breaking characteristics is proposed.

摘要

对用于红外 (IR) 和太赫兹辐射范围的基于戈莱单元的光声探测器 (OAD) 进行了分析综述。介绍了从 Bell、Hayes 和 Goley 的第一部作品直到现在的 OAD 发现和发展的历史。注意到了 OAD 的优点；它们包括在广泛的光谱范围内恒定和高灵敏度以及热探测器中最高的检测能力。考虑了膜的主要特性，即 OAD 的主要元素，并分析了石墨烯（最优选的膜材料）的物理特性。提出了三个 OAD 设计组：具有光学信息读取和基于电容器的麦克风的单个单元、具有充气室的选择性检测器和矩阵检测器。估计表明，使用 SLG-石墨烯膜可以创建具有数十微米大小和极高灵敏度的单元的 IR 和 THZ 辐射探测器。一种新的矩阵太赫兹光声探测器设计方案，采用六石墨烯 (C) 制成的膜提出了具有破纪录特性的\({}_{63(6)}\)。
