| 摘 要： | 最佳曝光量是全息技术的重要参量。曝光量在光度学里的单位是lx.s,在辐射度学里的单位是μJ/cm。文章给出了两种单位之间的换算关系,实现了用照度计（lx）测量以μJ/cm^2为计量单位的曝光量。通过实验进行了验证,测量结果与参考值很接近,实验结果比较理想。

| Abstract: | The optimum exposure is the important parameter in holography. And the unit of the exposure is lx·s in photometry,while μJ/cm2 in radiometry. In this paper,the conversion of unit between photometry and radiometry is achieved,and the measurement of exposure in μJ/cm2 by luminometer is realized. Experiments show that the measurement results are very close to the reference value,the results are satisfactory. |
