Fig. 7.

Holoscopic reconstruction of a grape comparing digital refocusing to the one-step reconstruction. (a) Cross-section from the volume refocued in one layer. (b) En face image at the virtual focus after the digital refocusing. (c) En face plane after the same digital recofusing operation as (b), 160 μm above the virtual focus. Since each depth is not independently brought into focus, defocus blur is still visible away from each virtual focus. (d) B-scan of the one-step reconstruction. (e) En face image at same location as (b). (f) En face image at same location as (f). Defocus is corrected since the one-step reconstruction brings every plane into focus. The NA was 0.14 (confocal parameter was 28 μm). Figure adapted with permission from [102].
