| 内容記述 | The accuracy of the measurement of the slit width with Fraunhofer's diffraction phenomenon was investigated. The investigation was made especially with regard to the effects of the slit width of the collimator on the measured values. The writers considered the exposition as giving a suggestion concerning the slit width of the collimator. The results were as follows (1) The distance l between the slit and the screen receiving the diffraction patterns had no effect on the results of the measurement. (2) In i =0.0001 rad. (the largest angle of incidence on the plane of the slit), the relative errors of the measured values were negative and had a maximum only when s (the slit width to be measured) was narrow, and as s increased, they turned to positive and had a maximum. In i =0.0005 rad. and i =0.0010 rad., the relative errors were always negative, and a maximum value and a minimum value were detected, according to the increase of s. In three cases mentioned above, the curves which expressed the relations between the relative errors and s, showed a concave and a convex. These appearances differed from those drawn on the previous exposition. Through these facts, the writers concluded that the systematic errors originated in the effect of the slit width of the collimator were a little as compared with the accidental errors in the measurement, and that the light-source might approximately regarded as a point lightsourece. However, in i =0.0010 rad., when s was enlarged beyond 0.18 mm, the relative errors increased always over 5% and the effects of the slit width of the collimator were observed remarkably. Over i =0.0015 rad. , as the effect of the slit width of the collimator grew mightily, the relative errors increased rapidly and linearly in accordance with the enlargement of s. Therefore the slit of the collimator was not to be regarded as a point light-source in these cases. However, in these cases, the relative errors were limited within 5% when s was less than 0.05 mm. (3) Except in the case of i =0.0001 rad. (in this case, the effect of the slit width was negligible entirely), all the errors were negative values strangely. (4) A method of correcting the errors originated in the effect of the slit width of the collimator was developed, using the values calculated on the exposition mentioned previously. | |||||
