IR matrix for positioning


I want to build a IR matrix for a project I am working on. With around 8 x 8 sender and receiver units along the sides of a 100 * 60 cm square. By pointing along the square the intention is that it will give me rough positioning according to which x and which y signal is broken.

I am at the beginning of the project and would like to know what IR senders and receivers would be suitable for this range (60-100cm). I hope that interference will be solved by multiplexing them.

Does anyone have any ideas or reference projects?

thanks in advance!
