摘要:

已知几种寄生效应会降低纯相位空间光调制器的性能。我们介绍了一个全面的模型,考虑到主要的:后面板的曲率,像素串扰和内部法布里-珀罗腔。为了高精度地估计模型参数,我们制作了闪耀光栅图案,并获得了第一和第二衍射级的强度响应曲线。该定量模型用于补偿全息图的制作,可以产生高保真度的光学模式。

英文摘要:

Several spurious effects are known to degrade the performance of phase-only spatial light modulators. We introduce a comprehensive model that takes into account the major ones: curvature of the back panel, pixel crosstalk and the internal Fabry-Perot cavity. To estimate the model parameters with high accuracy, we generate blazed grating patterns and acquire the intensity response curves of the first and second diffraction orders. The quantitative model is used to generate compensating holograms, which can produce optical modes with high fidelity.
