Description
Technical field
The present invention relates to pathology digital areas, and in particular to a kind of motion control method of microscope lens barrel on Z axis
And micrometron.
Background technique
Micrometron (motorized microscope) technology develops by ten several years, comparative maturity.But wherein
Principle of the model with full slice scanning (whole slide imaging) function mostly based on high-accuracy mechanical positioning, cost
It is high, limit its extensive use in low budget requirement user.
For essence, micrometron is mobile observed usually using three degree of freedom as traditional Manual Microscope
Sample: X, Y-axis horizontal plane are mobile and Z axis vertically moves.Wherein, Z axis moving lens directly determines micro optical system
Object distance, thus determine focusing imaging effect.
In order to guarantee that operational process is controllable and stablizes, Z axis and X, Y-axis also need high-precision positioning function, but design Z
The condition of the positioning system of axis and X, Y-axis are different: by gravity on one side Z axis, it is ensured that do not have in downward direction
(operation of lens barrel substantially passes through screw slider subband and moves, under the effect of gravity, it is ensured that sliding block closely connects always in dead zone
Lead screw is contacted, therefore the sliding block setting in motion on lead screw at once in lead screw rotation, without " lost motion ").
On the other hand, using high magnification when the camera lens of flash depth, being only located exactly in Z axis height can guarantee optical system
System is neat/position of focus at when just it is observed that clearly image, slightly move up and down and (usually only need several microns, and head office
Journey has several millimeters) make it is out of focus after, picture is just very fuzzy, the current height of Z axis can not be measured by it, in addition on sample
It is widely present and is not covered by sample and be thorough blank, the region that can not determine focus plane by micro-image, thus can not
Z axis height is measured when guaranteeing at an arbitrary position.This means that high absolute fix precision, price must be used high in the prior art
High Z axis measures kinematic system.Find out the position of current lens barrel neat/focus with target first by high-precision positioning device
The difference in height at place, then drive lens barrel to walk downward or upward by control running gear and reach ideal position.It is high-precision fixed
Position device is expensive, not convenient for safeguarding.
In addition, get a bird's eye view photo to shoot the full sheet of sample, be commonly provided on micrometron it is being separated with microlens,
Low range gets a bird's eye view camera, but it is usually unrelated with motion control.
