This 1D camera captures 2D images of things it can’t see
Arduino Team — June 25th, 2025 Yes, the title of this article sounds pretty crazy. But not only is it entirely possible through the lens of physics, but it is also practical to achieve in the real world using affordable parts. Jon Bumstead pulled it off with an Arduino, a photoresistor, and an inexpensive portable projector. Today’s digital camera sensors are the result of a fairly linear progression from a camera obscura up through film...
