Electric control liquid crystal bionic imaging micromirror, preparation method and optical microscope

Abstract

The invention discloses an electric control liquid crystal bionic imaging micromirror which comprises a first pattern electrode, a first substrate, a second pattern electrode, a first liquid crystal orientation layer, a liquid crystal layer, a second liquid crystal orientation layer, a common electrode and a second substrate which are sequentially arranged from top to bottom in parallel. A first micro-hole near one end of the first pattern electrode and led out from the first pattern electrode through a electric connection line and another electric connection line led out from the common electrode are respectively connected to two ends of a first external control signal U1. A second micro-hole near one end of the second pattern electrode and led out from the second pattern electrode through a electric connection line and another electric connection line led out from the common electrode are respectively connected to two ends of a second external control signal U2. The imaging micromirror according to the invention can solve the technical problem that the existing imaging micromirrors cannot combine the imaging functions such as bright field and dark field imaging detection, high-definition and low-definition imaging detection, light field and staring imaging detection, light field and conventional plane imaging detection and the like.

Description

technical field [0001] The invention belongs to the technical field of optical microscopic imaging and control, and more specifically relates to an electronically controlled liquid crystal imitation imaging micromirror, a preparation method and an optical microscope. Background technique [0002] Bionics and biological vision research shows that the human eye has formed a unique visual mechanism after long-term evolution, which can efficiently perform controlled collection of light wave energy, block generation of photoelectric signal clusters, cooperative transport of bioelectronic signal neural networks and Brain mapping, image information weighting processing, utilization, feedback calibration and light control, etc. The bionic imaging architecture developed based on the above characteristics of the human eye in collaborative imaging has been widely used in the field of optical imaging technology.

Problems solved by technology

[0003] However, the existing optical microscopic imaging technology has some technical problems that cannot be ignored: First, because it cannot imitate the human eye by physical means through a large-scale densely packed cone and columnar visual cells in the macular area, and the light The signal is converted into a bioelectronic signal and transmitted to the brain through the optic nerve network to form a high-definition image (including red, blue, and green color images of cone cells and colorless gray images of column cells in dark night conditions), so It does not have the imaging function compatible with strong light and low light sensing; second, because it cannot physically imitate the densely packed photosensitive cells based on the macular area of ​​the human eye and the sparsely distributed photosensitive cells outside the macular area, so its It does not have the high- and low-resolution partitioning imaging function that can greatly reduce the amount of imaging data, and it is impossible to concentrate the limited visual imaging and information processing resources on a specific area or target to obtain the best imaging effect, and roughly Sensing other optical clues that potentially affect visual cognition and judgment; third, it cannot imitate the function of changing the imaging direction, orientation or target of the macular area based on eyeball rotation through physical means, as well as through eyeball focusing, Focusing, etc. to reselect the imaging target function; fourth, it cannot imitate the pupil adjustment of the human eye using photosensitive imaging light energy; fifth, it cannot realize the functional imitation imaging mode and the conventional planar imaging mode through physical means Electrically adjustable switching between
