Is it posible to create flat sensor to sense a typical laser & send out signals to determine XY coordinates.?

Question

Is it posiible to create flat sensor which would sense a typical laser light and send out signals to determine the X and Y coordinates on the flat sensor surface...?

Basically I want to create a circular flat board which should get higlighted on sensiing laser beam. Not hte entire board, but only the XY corrdinates.

Answer 1

This is possible, use light detecting board. This will be expensive.

Clever system is to use TV camera that digitizes signal, look at data with a computer using pattern recognition technology to "see" the laser. This is much cheaper.

An old video game used to work by using a lens in a simulated gun that read when the location pointed to on a CRT was refreshed. Comparing the timing, it knew where you were pointing.
