# Properties

title: Raspberry Pi Camera Calibration Jig

description: |                             # required | paragraph
  A 3D-printed jig to uniformly illuminate the Raspberry Pi camera module's sensor, for the purpose of calibrating its response to different colours of illumination.  This enables flat-field correction, and also the unmixing of colour channels.  As the off-centre lenslet array means that (with uniform angle-of-incidence) the pixels at the edge suffer from significant crosstalk relative to the centre, correcting for varying colour response results in much truer colour representation.

intended-use: |                            # recommended | Paragraph
  Calibrating the Raspberry Pi camera module for colour response.
