After selecting the configuration inputs above, a user can explore interactively plots and tables with average lateral resolution in [lp/mm] and average minimum resolvable object size in [mm] using modulation transfer function (MTF) per target and per distance between a Lytro Illum camera and the reference object containing 9 circular targets inside of FOV. The average value is computed over 5 replicate acquisitions per configuration. Figure 1 shows the measurements accessibble via the web interactive interface.
The accessible information has been extracted from 1,800 light field images ~ 288 GB. Raw light field images were decoded using the software provided by the camera manufacturer (Lytro Power Tools Beta 1.0). One decoded 4D light field image has dimensions: 14 (S) x 14 (T ) x 541 (U) x 376 (V ) and 3 color values per pixel ~ 160 MB.
The number of images corresponds to the following variations:
