Polarisation cameras
Many materials effect the polarisation of light falling on to them. While this has been known in scientific experimentation for many years, realising the techniques for automated inspection has been challenging. However, now the first polarisation cameras are coming to market with polarisation applied to individual pixels or lines. This opens up applications such as seeing the stress in clear glass, checking the weave of carbon fibre, detecting the difference between paper and plastic and identifying foreign bodies in tissue. Please talk to us if this technology may be of interest to you.

Lightfield cameras
Fitted with adapted microlenses on each pixel like a Bayer camera has different colour filters, a lightfield camera allows different depths to be in focus in adjacent pixels. With between 4 to 16 pixels being treated as a single super pixel, lightfield cameras have a different focal depth on each pixel. The result is for each superpixel it is possible to achieve a far deeper depth of field as each one of the super pixel's elements has a different focal plane.
