    • PROBLEM TO BE SOLVED: To provide a plenoptic otoscope enables three-dimensional and/or spectral imaging of the inside of the ear to assist in improved diagnosis of inflammations and infections.SOLUTION: The plenoptic otoscope comprises: a primary imaging system; and a plenoptic sensor. The primary imaging system comprises: an otoscope objective 320; and relay optics 330, which cooperate to form an image of an inside of an ear at an intermediate image plane. The plenoptic sensor includes a microimaging array positioned at the intermediate image plane and a sensor array 350 positioned at a conjugate of the pupil plane. An optional filter module may be positioned at the pupil plane or one of its multiple conjugates to achieve three-dimensional imaging function and/or spectral imaging function.
    • 要解决的问题:提供全视耳镜能够使耳内的三维和/或光谱成像有助于改善炎症和感染的诊断。解决方案:全视耳镜包括:主成像系统; 和全光传感器。 主要成像系统包括:耳镜对象320; 以及中继光学器件330,其协作以在中间像平面处形成耳朵内部的图像。 全光传感器包括位于中间像平面处的微成像阵列和位于光瞳平面共轭处的传感器阵列350。 可选的过滤器模块可以位于瞳孔平面或其多个共轭体之一以实现三维成像功能和/或光谱成像功能。
