Electromagnetic Field Detector

[tot]

I am looking for an electromagnetic field detector that can detect use to detect the intensity of wave on a grid and return the results to a computer.
the higher the resolution the better.
does anyone know where this can be purchased?
how could one be designed?

You just described a digital camera...

You need be more specific: What is the frequency range? Is bolometric detection enough or do you need to know the frequency of the radiation? What kind of sensitivity do you need.

I would need it to work with wavelengths outside of the visible spectrum.
I don't need it to tell me the wavelength, but I just need to know the intensity.
I will read about bolometric thank you for the keyword.
