Title:
ZOOMING LIQUID LENS BASED ON MAGNETIC FIELD REGULATION AND CONTROL, AND OPTICAL AMPLIFICATION INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2022/088423
Kind Code:
A1
Abstract:
A zooming liquid lens based on magnetic field regulation and control, and an optical amplification instrument, which belong to the field of liquid lenses. The zooming liquid lens based on magnetic field regulation and control comprises: a cylindrical cavity (1), wherein two kinds of transparent liquids (3, 4) which do not dissolve each other are packaged therein; a magnetically conductive layer, which is attracted to a lower surface of a bottom plate (5) of the cylindrical cavity (1), wherein a magnetic field perpendicular to the bottom plate (5) is uniformly distributed on the magnetically conductive layer; and nano magnetic particles, which are grafted with functional groups and deposited on an upper surface of the bottom plate (5), wherein an aggregate form of the nano magnetic particles changes along with a change in the intensity of the magnetic field, so as to adjust hydrophilic and hydrophobic properties of the upper surface of the bottom plate (5), and thus achieving the aim of zooming.
