论文摘要
图像传感器是许多对现代科学非常重要的成像技术的骨干,在生物医学中特别相关。理想的图像传感器应通过所有电磁频谱(较大的带宽)可用,以满足许多显微镜应用的需求,应该很快(每秒数百万帧),并且应该便宜,以确保医疗保健系统的可持续性。但是,当前的图像传感器技术在带宽,成像率或价格方面具有根本的限制。在这里,我们简要概述了一个替代图像传感器概念的原理,称为单脉冲光声电磁检测(速度)。速度利用光声(光声)断层扫描的原理来克服当今图像传感器的几个硬限制。具体而言,速度传感器可以以高框架速率(每秒数百万帧)和低成本的大量电磁频谱进行操作。使用模拟,我们证明了速度方法的可行性,并讨论了其实施的步骤。
Image sensors are the backbone of many imaging technologies of great importance to modern sciences, being particularly relevant in biomedicine. An ideal image sensor should be usable through all the electromagnetic spectrum (large bandwidth), it should be fast (millions of frames per second) to fulfil the needs of many microscopy applications, and it should be cheap, in order to ensure the sustainability of the healthcare system. However, current image sensor technologies have fundamental limitations in terms of bandwidth, imaging rate or price. In here, we briefly sketch the principles of an alternative image sensor concept termed Single-pulse Photoacoustic Electromagnetic Detection (SPEED). SPEED leverages the principles of optoacoustic (photoacoustic) tomography to overcome several of the hard limitations of todays image sensors. Specifically, SPEED sensors can operate with a massive portion of the electromagnetic spectrum at high frame rate (millions of frames per second) and low cost. Using simulations, we demonstrate the feasibility of the SPEED methodology and we discuss the step towards its implementation.
