摘要

太赫兹时域成像系统由于成像带宽宽,所捕获的图像信息丰富。然而,最先进的太赫兹时域成像系统的速度仍然受到其单像素成像方式的限制。在这里,我们提出了通过太赫兹焦平面阵列的太赫兹时域成像,这消除了对机械光栅扫描的需要。我们演示了分辨率高达2.9太赫兹的63像素太赫兹图像。

Broadband Terahertz Time-Domain Imaging via a 63-Pixel Focal-plane Array
Images captured by terahertz time-domain imaging systems are information rich because of the wide imaging bandwidth. However, the speed of the state-of-the-art terahertz time-domain imaging systems is still limited by their single-pixel imaging modality. Here, we present terahertz time-domain imaging via a terahertz focal-plane array, which eliminated the need for mechanical raster scanning. We demonstrate resolving 63-pixel terahertz images up to 2.9 THz.
