Description
【Technical field】
The present invention relates to optical measuring device is and in particular to a kind of intelligibility measure device.
【Background technology】
The application of translucent product and opaque products is quite varied, and Related product includes glass, plastic sheeting, plastic bottle
Deng.Different application demands is different to the optical performance requirements of product；As the glass being adopted for greenhouse, it usually needs
Higher optical transmittance is so that receive sufficient indoor illumination；And be used for packing the transparent sheet that product adopted and then need
The article in packaging can clearly be recognized.Therefore, the definition (Clarity) to translucent and opaque products and mist degree
Etc. (Haze) optical property parameter measures assessment and is significant.
Mist degree, according to GB/T 2410, is defined as deviateing 2.5 ° of scattered lights in addition of incident light axis through sample
The ratio of flux and transmission total light flux.Definition (transparency) is used for evaluating the light transmission of sample, according to standard ASTM
D1746 specifies, in intelligibility measure light source for measuring with respect to sample plane to corner must 0.025 ±
Within 0.005 °；Meanwhile, receive the receiving plane of end detector corner to be limited in 0.1 with respect to sample plane ±
Within 0.025 °, definition is defined as the regular light transmittance that sample measures under above-mentioned geometrical condition.So little in order to realize
To corner, in prior art, typically realized by distance, thus, such measuring apparatus volume is general very big, transport
Inconvenience, also cannot be carried out on-line measurement.
For this reason, BYK publication number is the transparent material optical parameter measurement device of US8749791B2, right in the program
The measurement of definition be by arrange central detector and annular detector measure respectively the regular transmission light of sample with
And the scattered light at specified angle, and realize the evaluation of definition by the reading of analysis center and annular detector.
Meanwhile, 3M discloses the optical property sensor of Patent No. CN101680837A, transparent in the program
Paraboloidal mirror is arranged on the emitting light path of perforate on integrating sphere axle in the measurement scheme of rate, via the light of sample transmission and scattering
Line is reflexed to by the paraboloidal mirror being arranged on perforate emitting light path on integrating sphere axle and realizes at transmittance sensor specifying angle
Total photometric measurement in degree region.
Make a general survey of two above patent it is seen that, BYK scheme to scattered light measurement just for limitation angle at scattering
Light, and the scheme of 3M then measured directly be total shading value in a certain region, not only not can completely reflection via treating test sample
Scattering light distribution information in whole specified angle after product transmission and scattering, and the intelligibility measure that standard difficult to realize requires
Condition, taking the scheme of BYK as a example it is assumed that sample to detector distance as 50cm, then the center of measurement rules transmission is visited
Surveying device sensitive surface size should be within 0.87mm, and the external diameter of annular detector need to be within 21.8mm, and existing single channel detects
Device technology can hardly reach this requirement；Importantly, due to the beam angle very little collecting measurement in intelligibility measure, right
Also very high in the requirement of beam alignment；If mechanical vibration or light path adjustment are not, minimum deviation of the alignment also can be to
Whole measurement result produces impact.And for the scattering property sample different from standard sample, and the method measurement error will
Can be very big, and then affect the evaluation to sample definition and compare.Additionally, in traditional intelligibility measure, if real
Scatter distributions measurement in existing low-angle, generally by the way of switching receives the position of diaphragm or rotates receptor, relatively
Time of measuring is longer, inefficient, and the rotation precision of receptor also has strong influence to the accuracy of measurement result simultaneously.

In apparatus of the present invention, the illuminating source of the first light-source system or light-emitting window can pass through relative to the subtended angle of sample
Adjustment the distance between fibre bundle input and sample accurately to control, and the aperture of fiber unit can be very little, can
To realize the requirement that little opposite side corner connection is received, the intelligibility measure that the standard of realization specifies in the device of compact volume.Additionally, passing through
The ordered arrangement of fiber unit can realize the light distribution situation of the transmitted light in optic fibre input end for the sample, and then obtains quilt
The angle scatter properties of test sample product, not only can more accurate evaluation definition, also to the scattering propertiess research of sample with
And improvement has directive significance.
Compared with traditional scheme, instant invention overcomes leading to because sample transmissison characteristic is different in traditional scheme
The shortcoming that between different samples, definition is more objective than less, inaccurate, error is big, but saturating by measuring the rule of sample
Penetrate light and transmission light distribution, obtain accurate definition and angle scattering data, there is applied widely, certainty of measurement
High, fireballing advantage, and make the relatively more more objective, more meaningful of definition between different samples.
