In this Letter, we present a novel imaging concept that a single imaging system can image different spectral bands with different aperture sizes. It is achieved by using a filter with different transmitted spectral bands in different annular rings as the aperture stop. This concept will enable more efficient system configurations and practical clinical applications. We have demonstrated this concept with a dual-mode near-infrared fluorescence image guided surgical system.
在本信函中,我们提出了一种新颖的成像概念,即单个成像系统能够以不同的孔径大小对不同光谱带进行成像。这是通过使用一种在不同环形区域具有不同透射光谱带的滤光片作为孔径光阑来实现的。这一概念将实现更高效的系统配置和实际临床应用。我们已通过一种双模式近红外荧光图像引导手术系统验证了这一概念。
