My ultimate dream is a pair of magical glasses with a small knob on it, which when turned adjusts the wavelength you can see from deep radio all the way to high energy gamma. Just imagine seeing the entire spectrum.
Not sure the other spectrums of light are intense enough on average for such glasses to work without them also emitting all spectrum of light (essentially a walking radar/lidar/X-ray/etc… machine).
For example we of course have these types of “glasses” for infrared which is fine for humans because we give off significant quantities of infrared radiation, but lesser known is we also emit light in the visible spectrum, it’s just not enough intensity for our rods/cones or inversely our rods/cones are not sensitive enough to observe the visible light we emit. Anyway your invention would be cool, even if it just ratcheted up the existing visible light spectrum enough we could see ourselves glowing in the dark…it would give people a new appreciation for Carl Sagan’s quote that we are made of stardust.
