And on the other hand, they've created a handheld device that sees colors we can't.
Application: can detect things that are camouflaged.
The Image Replication Imaging Spectrometer (IRIS) system was developed by Andrew Harvey and colleagues at Heriot-Watt University in the UK.
The cells in the human retina that detect coloured light are sensitive to only certain parts of the spectrum – red, green or blue. All perceived colours are a mixture of this basic palette of colours. Digital cameras work in a similar way, also using separate red, green and blue filters or sensors.
By contrast, the IRIS system has a greater basic palette, of 32 or more "colours" – bands of the light spectrum. It works by dividing an image into 32 separate snapshots, each containing only the light from one of its 32 spectral bands.
