Figure 12
Comparison showing the original images and the deconvolved images. The four images on the left are original images under different conditions. The experimental conditions are: (A1) 10× objective (NA = 0.4) and 4.6 µm-thick GGG:Tb. (B1) 10× objective (NA = 0.4) and 4.6 µm-thick GGG:Tb. (C1) 40× objective (NA = 0.6) and 4.6 µm-thick GGG:Tb. (D1) 40× objective (NA = 0.6) and 20 µm-thick GGG:Tb. The four images on the right correspond to the respective PSF deconvolution results of the images on the left. To show the details more clearly, (A1), (B1), (A2) and (B2) are only part of the original image. To show the spatial frequencies from 62.5 line-pairs mm⁻¹ to 1000 line-pairs mm⁻¹, (C1), (D1), (C2) and (D2) are mosaics of four original images.
