Technology.Referring to Fig. 2, it is a kind of liquid lens for microcirculation of nail rugae imaging device that the utility model preferred embodiment provides
Autofocus system schematic diagram.When the light injection imaging receiver passage 3 with microcirculation of nail rugae information, and pass through successively
First focus eyeglass 301, reflecting prism 302, second focus eyeglass 303 (normal optical glass lens) and liquid lens 304 into
As into described image reception device 4, computer 6 is passed to after opto-electronic conversion and analog-to-digital conversion, the computer 6 is always according to working as
The described image data of preceding reception, quickly curvature is sent after being calculated by auto-focusing algorithm to the liquid lens controller 7
Adjust instruction, the instruction indicate that the liquid lens controller 7 changes the curvature R of the liquid lens 304, so as to adjust described
The focal length of liquid lens 304, ensures that optical imaging system can focus real-time so that in described image reception device 4
The picture contrast of acquisition reaches maximum, so as to show stable image or video on computer 6.
For the liquid lens 304 using two kinds of liquid that cannot be merged, one of which is conductive aqueous solution, another
It is nonconducting oil.Both liquid are installed in small-sized tubular container, and the crescent moon quite with glass lens is formed in container
The curved surface of type, the curvature R of curved surface changes so that the focal length of liquid lens 304 changes.The wettability effect of the water repellent surface of oil
(therefore named electrowetting) can be changed using voltage, make surface become more hydrophilic (moistening) or more water resistant.Due to original water resistant (or
It is hydrophilic) surface become now more absorb water (or water resistant), oil reservoir has to change its form, therefore, by adjusting in container two
The DC voltage at end, it is possible to change the curvature R on crescent surface at two kinds of different liquid junctions, that is, liquid lens
304 focal length.Liquid lens controller 7 is exactly to change its curvature R by varying the driving voltage of liquid lens 304, so that
Change its focal length.The different driving voltage of liquid lens 304 corresponds to different curvature R values, and driving voltage is a total of N number of, therefore
Corresponding N number of R values (from R0, R1......RN), the curvature R changes for controlling liquid in liquid lens 304 by voltage carry out zoom,
Zooming range is big, the penetration capacity of optical axis stable, light is strong, and mechanical oscillation are not present in focus process, and noise is small.In addition, liquid
Somascope piece 304 is compact-sized, compact, and durability is good.
The computer 6 is when the contrast for detecting the nail fold micro-circulation images changes, to the liquid mirror
Piece controller 7 sends curvature adjustment control instruction, the liquid lens controller 7 is controlled the curvature R of the liquid lens 304
Gradually changed within the scope of one；In this process, the computer 6 constantly detects the contrast of the nail fold micro-circulation images
Degree, when finding highest contrast, sends the instruction of curvature stability contorting to the liquid lens controller 7, makes the liquid
Eyeglass controller 7 controls the liquid lens 304 to stablize in the curvature R corresponding to the highest contrast.
However, it is to be understood that, the above-mentioned embodiment using liquid lens technology of auto is intended only as the practicality
New more excellent embodiment, allows for microcirculation of nail rugae imaging device of the prior art and is required for manually adjusting every time
Burnt mode carries out focusing and finds picture rich in detail, as long as user slightly shakes, the image plane of imaging system is just removed, and causes to need
Again manual focusing, system focusing time to grow, use highly inconvenient.Therefore, by setting in optical imaging systems
Put it is a piece of can automatic focusing liquid lens 304, even if the finger of user is slightly shaken, liquid lens 304 also will be according to meter
The curvature adjust instruction of calculation machine 6 is focused real-time, and clearly Microcirculatory Image is presented to defocused, realizes auto-focusing；
So that the microcirculation of nail rugae imaging device, during image or video is obtained, the hand of user can move everywhere, should
Optical imaging system can be moved with the movement of human hand, not interfere with system imaging quality, and without manually adjusting
Jiao, further increases the observation convenience of microcirculation of nail rugae.In other embodiments, the microcirculation of nail rugae imaging device
