用相机测量金刚石膜透光性的研究

Measurement of the light transmittance of diamond films with a camera

为了方便测量、记录和交流金刚石膜的透光性,对用相机测定金刚石膜透光性的技术问题进行了研究。其原理是由相机的感光度、光圈、快门速度先得到一张级差为20%的25级金刚石膜透光性的速查表。测量中,得知膜的快门速度后查表,即可知膜的透光性级数和透光率。该法表征金刚石膜透光性的方式,可适用于多散点单参数膜25级平面坐标图示法和单散点多参数膜相关信息元素的多项式法。该方法快速方便、简单可靠,无需大型设备,保证了金刚石膜的完整性,觧决了整片金刚石膜透光性的测量、表征和分级的问题。

To facilitate the measuring, recording and communicating of the light transmittance of diamond films, the technical problems of the transmittance measurement of diamond films with a camera was studied with a differential o The principle was to get a quick reference table of the diamond films transmittance f 20% and 25 grades by the camerars sensitivity, aperture, shutter speed . Thetransmittance grade and transmittance ratio of the diamond film could be known by looking up the quick reference table after measuring the shutter speed. The representation of the light transmittance was suitabl.e for multi-scatter points, single-parameter, 25-grade, plane coordinate graphic method and single-scatter point, multi-parameter, related information polynomial method. The method was rapid, convenient, simple and reliable with no use of large-scale equipment and maintaining the integrity of the diamond films. The problem of how to measure, characterize and grade a whole diamond film was solved successfully by this method.
