Choosing a proper lighting approach is a crucial
task in designing visual inspection systems. It becomes especially
challenging for complex-shaped objects, which change
the direction and distribution of incoming light in various
ways. We overcome this challenge by constructing a light
field display and deploy it as a highly tunable lighting device.
By programmatically controlling the spatial position of the individual
light sources while simultaneously controlling their
angular direction of emission, an object-specific light field can
be generated, which highlights the features of the object under
test with maximum contrast. We explain the calibration
procedure, the rendering pipeline and present first results of
the device’s performance.
