Receive device 11.There are photosensitive sensor, such as PSD on optical receiver, high detection accuracy can be obtained.
Testee is vertical or horizontal placement.For two different situations, the position of other components should be made accordingly
Adjustment.What this will be appreciated that.
When measurement, the first situation is: guide way is static, and measured workpiece is allowed to translate along guide way, and detection device is without edge
The translation of guide way.It is illustrated here in conjunction with Figure of description Fig. 1.In Fig. 1, steadily placed using the prior art tested
Object；Translate its left and right, if its is in uneven thickness, through the invention and its accordingly mathematical computations, available tested
The changing value of object thickness and thickness.It is understandable above.Especially, it should be noted that: using the present invention, when light
When length is greater than measured workpiece length, hot spot changing value is greater than the variation of thickness of workpiece, therefore, even if thickness of workpiece variation is very
It is small, it also can detecte out the variation of this very little, so, the present invention has very high resolution ratio, can be realized high-precision and detects.

Portal or the circularity of outer circle, roughness.If allowing testee 3 (pored component) while rotating about the axis thereof, axis is had concurrently
To movement, the cylindricity of hole or outer circle can also be measured.It also can measure and portal or the size of outer circle, hole or outer in conjunction with the prior art
Circle is relative to the beating degree on other surfaces, concentricity, position degree and other Form and position errors.
When measurement, the 4th kind of situation is: making testee 3 (pored component) static, detection device is allowed to rotate about the axis.Together
Sample, which can measure, to portal or the circularity of outer circle, roughness, cylindricity, size, beating degree, concentricity, position degree and other morphemes
Error.
The present invention can be used for the measurement of finished product, semi-finished product, blank quality index, such as be directed to size, shape and position
Set the inspection of error.It is contemplated that the present invention may be use with measurement needed for production process control, for example, the scheme in Fig. 1 can extend
Monitor or check applied to the deformation for the expanded by heating for monitoring components in production process, during scientific experiment components by
Power deformation.It can be also used for checking mechanical parts wear extent of deterioration etc..
When detecting inner surface, for through-hole, light can be passed through inside hole or be passed through from the outside in hole.Other correlations
The position of components adjusts accordingly.This is not difficult to accomplish.
By size and shape measured by the present invention, position data, can be fitted the pattern of equipment component, shape,
Structure feature and its variation.With important learning value.
When detection bar is whole, manufacture is easy, but is not very convenient sometimes when placement workpiece.It is split type for detecting bar
When structure, detection bar is dismantled, can relatively easily place workpiece, after placing workpiece, detection bar is assembled into whole use.
Beneficial effects of the present invention: first, when the length of light is greater than the length of workpiece, can will test as the result is shown
It must become apparent, it can shown after amplifying the feature at tested position；In one test, optical transmitting set is to optical receiver
The distance between be it is constant, hot spot stablize.The above is conducive to improve detection accuracy.Second, it can measure size, in parallel
The many kinds of parameters such as degree, verticality, gradient, angle, circularity, cylindricity, roughness, position degree, profile tolerance.Third, Ke Yiyong
