Plane mirror is replaced with specific corner mirror, to realize the technique study for increasing photoelectric auto-collimator measurement range.
Background technique
Autocollimator is the important kind of measurement instrument for small angle measurement using optical autocollimating principle.Since it is with higher
Accuracy and measurement resolution, thus be widely used in accurate measurement work, such as: angle measurement, plate it is flat
The measurement of face degree, shafting angle shake measurement, straight line degree measurement etc. the autocollimator of guide rail plays an important role.Autocollimatic
Straight instrument is due to possessing higher accuracy and Measurement Resolution, so by being largely used in: angle measurement, the angle shaking of shafting
Measurement, the straight line degree measurement of guide rail, angle measurement etc..Since the measurement accuracy of auto-collimation instrument is more demanding, add
The restrictive condition of its measurement range is excessively single, so being in recent years all concentrated mainly on the research of auto-collimation instrument to its precision
In raising.However the photoelectric auto-collimator sold on the market now is with German MOLLER company ELCOMATHR and ELCOMAT
Series is representative, and product is substantially accomplished very high precision.However the measurement range of auto-collimation instrument is due to its own knot
The characteristics of structure, can not effectively improve always, to greatly limit its using and develop in field of industrial measurement.
Operating distance, the restriction relation formula of measurement range and the bore of its object lens of known 2 D photoelectric autocollimator are as follows:
Wherein L indicates the operating distance of photoelectric collimator, and β indicates measurement range, and D is aperture of objective lens.
According to formula (15), existing photoelectric auto-collimator will necessarily sacrifice its survey when measuring the measurement target of long range significantly
Range is measured, or increases the measurement range of autocollimator by the method for the bore for increasing its object lens.The former makes auto-collimation
The operating distance and measurement range of instrument cannot be considered in terms of, and the latter will increase the cost and weight of autocollimator, while aperture of objective lens
Increase so that the convergence of some aberrations becomes difficult, so that design difficulty increases.
