Description
Technical field
The utility model is related to technical field of electro-optical measurement, more particularly, to flatness detection technique field.
Background technology
Flatness is belonging to the one kind in form and position tolerance, refers to macroscopical height of concave convex relative ideal plane that body surface has
Deviation.In traditional detection method, the measurement of flatness generally has：Feeler gauge/clearance gauge mensuration, fluid level method, laser are put down
Face interferometer measurement method（Optical flat interferometric method）, level meter/digital gradienter mensuration and beat table mensuration.
Clearance gauge mensuration, only needs a set of portable clearance gauge whenever and wherever possible to carry out the bigness scale of flatness.At present
Many factories are still detected using the method.Because its precision is not high, conventional most thin clearance gauge is 10um, and detection efficiency is relatively low,
Result is not comprehensive enough, can only detect part edge.
Fluid level method, based on linker operation principle, is adapted to the flatness of the continuous or discrete big plane of measurement, but survey
The amount time is long, and temperature sensitive, is only applicable to the relatively low plane of certainty of measurement.
Laser plane interferometer mensuration, most typical usage is optical flat interferometric method.But it is main bright and clean small flat in measuring
The measurement in face, such as the mobile phone measurement of planeness, the mobile phone center measurement of planeness, the working face of gauge, optical lens.
Level measurement method, is widely used in linearity and the measurement of planeness of workpiece surface.Certainty of measurement is high, stability
It is good, small volume, easy to carry.But need to move instrumented site repeatedly when being measured with the method, record the data of each measuring point, take
When, it is laborious, adjustment time is long, and data processor is cumbersome.
Table mensuration is beaten, typical case's application is flat amesdial and three-coordinate instrument, wherein excellent with three-coordinate instrument as most widely used
It is general.Indicator is moved on testing sample during measurement, and data of each measurement point relative to measuring basis are measured by selected layouting,
Again flatness error is assessed by data processing.But its is less efficient, a usual sample needs a few minutes, from 15ppm's
Expect to differ greatly.
