标题： Quantum undetected optical projection tomography

摘要： 量子成像使用未被探测的光子（QIUP）是一种新兴技术，它将照亮物体和投影其图像的过程解耦。因此，可以同时优化照明光和探测光的特性，以提高样品的对比度和相机的灵敏度。在这里，我们将QIUP与计算断层扫描结合，以实现三维（3D）红外成像。图像数据在810纳米波长下与标准硅相机进行注册，但提取的3D图像映射了样品在1550纳米波长处的吸收情况，这远远超出了相机的灵敏度范围。量子未被探测光学投影断层摄影（QUOPT）能够在难以检测的波长下实现无标记的体积传感，例如那些允许分子成像对比的波长，或者位于红外生物传输窗口内的波长。 显示英文摘要

摘要： Quantum imaging with undetected photons (QIUP) is an emerging technique that decouples the processes of illuminating an object and projecting its image. The properties of the illuminating and detected light can thus be simultaneously optimised for both contrast on a sample and sensitivity on a camera. Here, we combine QIUP with computed tomography to enable three-dimensional (3D) infrared imaging. The image data is registered with a standard silicon camera at a wavelength of 810 nm, but the extracted 3D images map the sample's absorption at a wavelength of 1550 nm, well beyond the camera's sensitivity. Quantum Undetected Optical Projection Tomography (QUOPT) enables label-free volumetric sensing at difficult to detect wavelengths, such as those that allow molecular imaging contrast, or those within the infrared biological transmission windows.
