This post is more of an awareness of a fascinating subject discussed yesterday with @Wendy in particular. Our discussion was focused on a new method called photon-pixel coupling, which allows the sampling of an enormous number of sensors in parallel.
The photon-pixel coupling method is truly ingenious because it solves two main problems in engineering: 1] an unlimited number of sensors and 2] their parallel sampling at video rate frequencies. Just imagine, we can read as many sensors as we wish.
How it works:
Basically, each sensor output is an LED. If you have 10000 sensors, the LED (output) of each is inserted in a LED array of 10000 elements, a LED matrix as the authors say. After that, the LED array is filmed by a video camera and the images are processed in real time by a computer. A software reads one pixel from each LED from the LED array picture/frame and converts it to numerical values. Thus, your LED array will be converted in a matrix (with 10000 elements) filled with numbers that can be processed as you wish in your software. I don't know if I was explicit but you can read their article here: https://www.sciencedirect.com/science/article/pii/S2215016119300901
Note that classic multiplexing is serial and photon-pixel coupling is parallel.
Schematics of the Photon-pixel coupling from the original article:
What I wander is if we can adapt the photon-pixel coupling to Arduino. I am new in the world of microcontrollers but I know Arduino can support a cam, a low fps cam, so it should be possible.
If you are a PhD student then:
