Chromatic confocal microscopy using liquid crystal display panels

Not Accessible

Your library or personal account may give you access

Abstract

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.
