  Plenoptic imaging enables a light-field to be captured by a single monocular
objective lens and an array of micro lenses attached to an image sensor. Metric
distances of the light-field's depth planes remain unapparent prior to
acquisition. Recent research showed that sampled depth locations rely on the
parameters of the system's optical components. This paper presents
PlenoptiSign, which implements these findings as a Python software package to
help assist in an experimental or prototyping stage of a plenoptic system.
