Photoacoustic imaging (PAI) has achieved remarkable growth in the past few decades since it takes advantage of both optical and ultrasound (US) imaging. In order to better promote the wide clinical applications of PAI, many miniaturized and portable PAI systems have recently been proposed. Most of these systems utilize fiber optic technologies. Here, we overview the fiber optic technologies used in PAI. This paper discusses three different fiber optic technologies: fiber optic light transmission, fiber optic US transmission, and fiber optic US detection. These fiber optic technologies are analyzed in different PAI modalities including photoacoustic microscopy (PAM), photoacoustic computed tomography (PACT), and minimally invasive photoacoustic imaging (MIPAI).

光声成像（PAI）由于同时利用光学和超声（US）成像的优势，在过去几十年中取得了显着的增长。为了更好地促进PAI在临床的广泛应用，近年来提出了许多小型化、便携式PAI系统。大多数这些系统都利用光纤技术。在这里，我们概述了 PAI 中使用的光纤技术。本文讨论了三种不同的光纤技术：光纤光传输、光纤US传输和光纤US检测。这些光纤技术以不同的 PAI 模式进行分析，包括光声显微镜 (PAM)、光声计算机断层扫描 (PACT) 和微创光声成像 (MIPAI)。
