摘要

光谱识别是高效机器视觉获取彩色目标高成像质量的关键。然而，单波段视觉传感器的双向响应对多光谱背景下的彩色目标的现场识别仍然具有挑战性。本文以鸟类的眼睛为灵感，提出了一种基于WOx/WSe2异质结的四色双向突触晶体管，并结合CdS的紫外光活性浮栅，实现了多光谱背景下图像增强和识别能力提高的生物鸟类视觉。在可见光波段表现出正突触反应，而在紫外波段表现出负突触反应。此外，由于UV负响应的贡献，其识别精度从58%提高到93.1%，并表现出了红隼的视觉行为。这项工作提供了一种有效的神经形态视觉来识别来自多光谱背景的特征签名。

Avian eye-inspired tetrachromatic-bidirectional synaptic transistor for multi-spectral recognition

The spectral recognition is key for efficient machine vision to obtain high imaging quality of color target objects. However, the bidirectional response within a single band of vision sensors is still challenging to in-site recognize color target objects from a multi-spectral context. Here, inspired by avian eyes, we propose a tetrachromatic-bidirectional synaptic transistor based on WOx/WSe2 heterojunctions with a ultraviolet (UV)-photoactive floating gate of CdS and realize the bio-avian vision with enhanced image and improved recognition under a multi-spectral background. The positive-synaptic responses are exhibited within the visible wavelength band while the negative response is for the UV wavelength band. Moreover, the bionic-kestrel vision behaviors are exhibited, such as the in-site enhanced color object images and the improved recognition accuracy from 58% to 93.1% due to the contribution of UV negative response. This work provides an effective neuromorphic vision to recognize the feature signatures from the multi-spectral contexts.

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
