low cost 2D realtime imaging spectroscopy

Hi,

2D realtime imaging spectroscopy in the visible spectrum could be done with a Kyobo Ereader with the mirasol display, a lens, and a webcam and software to drive the display and log data from the webcam.

A lens can project the image or light source onto the mirasol display, and each pixel or groups of pixels are set to be a certain colour, if no backlight is used, then the colour will only be reflected if it exists in the light source at that 2D coordinate. So if a colour sweep is done a full spectrum for that pixel can be measured with the webcam viewing the mirasol display.

total cost of project maybe $200 depending on the lens! :)

cheers, Jamie

You can do it for a demo for under $20 with a high dispersion diffraction grating with a lower dispersion prism at right angles on a standard Webcam CCD. Beware of infringing PE patents though.

Various amateur astronomy sites will give details.

Thanks, that's good for UFO hunting, as a normal camera won't be able to tell if its looking at a human made light or not, but a multispectral camera could see a different light spectrum from ET UFO's.

Still trying to catch a ride home, Maynard?

Hi,

Either that or trying to suggest a way to refute all of the supposed UFO videos, ie phoenix lights.

cheers, Jamie
