Abstract
The invention discloses an auxiliary method for facilitating the laser measurement on the dimension of a transparent member. The method comprises the steps of (i) coating powders; (ii) correcting a measurement result. Based on the auxiliary method, the refraction phenomenon during the laser measurement of the transparent member is avoided, so that the adverse effect of the complex refractive and reflective light on the measurement result is eliminated. Through correcting the measurement result, the measurement accuracy is ensured to meet the particular requirement of the actual detection.
Description
Technical field
The invention belongs to a kind of laser measurement householder method, be specifically related to a kind of householder method of laser measurement transparent member size.
Background technology
Laser is high-intensity coherent light, has monochromaticjty and directionality, because of but delicate metering detect perfect light source. Utilize the characteristic of laser can carry out the measurement of multiple physical dimension, this class is measured and has all been obtained compared with the more accurate result of previous methods. At present, laser measuring technique has obtained applying more and more widely in fields such as the automatic detections of accurate measurement, metering, production process.
The general principle of laser measurement is: laser instrument sends utilizing emitted light, be irradiated to workpiece back reflection, receiver receives reverberation, and the time interval that receives laser by measuring from being issued to calculates the distance of laser instrument and workpiece, thereby realizes laser ranging and the further measurement of workpiece size.
For transparent workpiece, Ear Mucosa Treated by He Ne Laser Irradiation also can produce refraction during to surface of the work except reflection, can again produce reverberation and refract light, according to laser measurement principle when refract light penetrates workpiece, so complicated light will affect measuring accuracy, even causes measuring completing.
Summary of the invention
The present invention produces the shortcoming that complicated reflection and refracted ray impact measure and proposes while there is laser measurement transparent member size in order to overcome in prior art, its objective is the householder method that a kind of laser measurement transparent member size is provided, guarantee measuring process is implemented smoothly, and measurement result is accurately reliable.
Technical scheme of the present invention is:
A householder method for laser measurement transparent member size, is characterized in that: comprise the following steps:
(I) coating powders
Measurement face in transparent member to be measured evenly applies one deck pressed powder, then carries out laser measurement;
The correction of (II) measurement result
Utilize contourgraph to measure respectively the size of transparent member to be measured in two kinds of situations of coating powders and coating powders not, as correction value, the result of laser measurement is revised by both differences.
The modification method of described step (II) measurement result can also be the opaque standard workpiece of making and transparent member same size to be measured, use respectively the size of laser measurement opaque standard workpiece in two kinds of situations of coating powders and coating powders not, as correction value, the result of laser measurement is revised by both differences.
Described pressed powder is that talcum powder or other particle size range are between 0.01m ~ 0.05mm and uniform opaque pressed powder.
The concrete grammar of described step (I) coating powders is for to put into paper container by transparent member to be measured, pour appropriate pressed powder into, shake gently paper container, after pressed powder is evenly attached to transparent member to be measured surface, be laid in the quality such as gauze or nonwoven softer material, powder unnecessary on workpiece is blown off gently with rubber pipette bulb, only retain the powder that surface of the work a layer thickness is 0.01 ~ 0.1mm.
The invention has the beneficial effects as follows:
Apply when householder method of the present invention ensures laser measurement transparent member and no longer reflect, eliminated refraction and the harmful effect of reflection ray to measurement of complexity in the past; By the correction to measurement result, ensure that the accuracy of measuring meets certain actual testing requirement.
Detailed description of the invention
