彩色共焦显微镜系统结合两个液晶显示器（LCD）面板的建议，并证明了表面轮廓。该系统的主要优点是三维（3D）成像不需要机械平移。由于物镜中的色差，实现了轴向扫描，而横向扫描则通过打开LCD上的不同像素来实现。物镜透镜的色差用于提供波长-深度编码，并且解码通过使用色散棱镜来实现。系统性能通过50 μm步进标准进行了验证，并通过洋葱表皮展示了3D成像能力。
A chromatic confocal microscopy system in combination with two liquid crystal display (LCD) panels is proposed and demonstrated for surface profiling. The major advantage of this system is no mechanical translation is needed for three-dimensional (3D) imaging. Axial scanning is realized thanks to the chromatic aberration in the objective, whereas lateral scanning is achieved by turning on different pixels on LCDs. Chromatic aberration of the objective lens is used to provide wavelength-to-depth coding, and decoding is realized by using a dispersion prism. System performance is validated with a 50 μm step standard and the capability of 3D imaging is demonstrated with an onion epidermis.
