Abstract The method of multifactorial orthogonal decision on diffraction efficiency (DE) of Fresnel hologram is proposed in this paper. The orthogonal table is designed for such major manufacturing parameters as beam ratio, expo sure, development time and developer density. With variance analysis, the conspicuous factors on DE are obtained, and the optimal technological conditions are established. In addition, by regression analysis to the conclusion, we obtain a fit rate of about 88% to the calculated and experimental results.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
