From: Snapshot depth–spectral imaging based on image mapping and light field
The SRFs of refocused images with different object depths at center wavelength 600 nm. The object depth of each figure is noted on the top. The object depth of the figures in first line are − 5 mm, − 4 mm, − 3 mm, − 2 mm, − 1 mm and 0 mm, respectively. The object depth of the figures in second line are 5 mm, 4 mm, 3 mm, 2 mm and 1 mm, respectively
