HyperCam is a Low-Cost Hyperspectral Camera That Captures What We Can’t See

Hyperspectral cameras can see things in the world that the human eyes can't by capturing information from across the electromagnetic spectrum beyond visible light. This type of technology has all kinds of interesting applications -- researchers are using the cameras to uncover secrets in old documents and paintings, for example.

The HyperCam is a new hyperspectral camera that aims to make the technology cheap enough to be casually used by the masses.

First-Ever Hyperspectral Photo of Auroras

Auroras are quite popular as a photo subject these days, especially for time-lapse photography, but a team of researchers in Norway recently snapped pictures of one in a way that hasn't been done before: with a hyperspectral camera. The special device can simultaneously capture multiple spectral bands of light. The composite photograph above was created by combining three such bands of light, with each one assigned a different RGB color.
