Fig. 10From: Ring-shaped bifocal lens used for fluorescent self-referenced holographic imagingThe cross section of the PSF of the conventional microscope (CM, - -) and the built RBL based holographic setup (SHS, ---), where the target, the 4 μm illuminating (530 nm) spot, is at different distances. X and Y denote the position on the detector and the relative intensity respectively. It can be seen, that the PSF of the SHS does not change significantly with the target distance, but the PSF of the CM changes.
