In this paper, we theoretically and experimentally evaluated the quality of volume phase transmission lenses stored in an environmentally friendly photopolymer. Holographic lenses (HLs) were obtained using symmetrical and asymmetrical experimental setups with the same positive and negative focal length and pupil diameter. The image quality was evaluated from the calculation of the modulation transfer function (MTF) by capturing the point spread function (PSF) with a charge-coupled device (CCD). A maximum frequency of 14 L/mm, reaching an MTF value of 0.1, was obtained for a negative asymmetrically recorded HL, evaluated at 473 nm wavelength. A theoretical study of aberrations was carried out to qualitatively evaluate the experimental results obtained.
在本文中,我们对存储在环保型光聚合物中的体相位透射透镜的质量进行了理论和实验评估。使用具有相同正负焦距和光瞳直径的对称和非对称实验装置获得了全息透镜(HLs)。通过电荷耦合器件(CCD)捕获点扩散函数(PSF),从调制传递函数(MTF)的计算来评估图像质量。对于在473nm波长下评估的负非对称记录HL,获得了14L/mm的最大频率,MTF值达到0.1。进行了像差的理论研究,以定性评估所获得的实验结果。
