There are cameras that can see infrared and ultraviolet, what about microwaves and other wavelengths?
If we had a camera that only images microwaves for example, could we see wi-fi and Bluetooth as they reflect off surfaces?
What are the main limitations of building something like this? Is it the size difference between wavelength and sensor size?
In: Physics
We definitely have sensors that can detect microwaves in detail however displaying them on a screen like you would a video or photograph would require a heavily processed image. Just like many of the images we have of planets, stars, and galaxies are not actually what they look like if you were to see them up close with a human eye. This is because the data that represents those non-visible wavelengths is processed so that we can see it. You might configure the software that processes it to represent any data that is 2.6 to 2.7 Ghz is colored blue and 2.8 to 3.0 Ghz is purple.
