We consider a technique for high-resolution image upconversion of thermal light. Experimentally, we demonstrate cw upconversion with a resolution of more than 200 × 1000 pixels of thermally illuminated objects. This is the first demonstration (to our knowledge) of high-resolution cw image upconversion. The upconversion method promises an alternative route to high-quantum-efficiency all-optical imaging in the mid-IR wavelength region and beyond using standard CCD cameras. A particular advantage of CCD cameras compared to state-of-the-art thermal cameras is the possibility to tailor and tune the spectral response leading to functional spectral imaging.
我们提出了一种用于热光的高分辨率上转换技术。实验上，我们演示了具有超过 200×1000 像素分辨率的连续波上转换，这是（据我们所知）热激发物体的高分辨率连续波上转换的首次演示。该上转换方法有望替代中红外及以上波长区域的高效率全光学成像，而无需使用标准 CCD 相机。与最先进的热像仪相比，CCD 相机的一个特别优势是能够调整光谱响应以实现功能光谱成像。
