Yes but how to do thisOK, the systems that I have used were to keep machines from running when hands or fingers were near moving parts. The TS has given no clue as to what this is for, or how important reliability and performance would be.
For home fabrication and applications I suggest small cheap lasers and phototransistors as detectors. Narrow beam LEDs are not available to most folks, and the logic to make the wider beam ones work gets large. With LEDs the beams need to come on in sequence and the opposite detector needs to be checked only at that time. And they do it a few times per second. Lasers could all flash at the same time, a few times per second, and all of the sensors could be checked at once. Much simpler.
Can be horizontal, but I need full details including components and circuitSome ramblings:
Keep beam width narrower than spaces , may need short focus lens on Tx., conical concentrator on Rx. Non modulated is simpler.
Can the beams be horizontal, less apt to collect trash?
What is your electronic knowledge level and experience? I doubt whether anyone on the forum is prepared to invest their precious time in designing and developing a complete custom system for you, especially when you can by a ready built and tested unit. If you insist on building your own, I would suggest you start doing some research on the subject so that you can design it yourself.Can be horizontal, but I need full details including components and circuit
A good light curtain is not simple, no matter what. How far apart can the light beams be? That is what the question about resolution means. Will you be able to produce the mounting arrangement to accurately point each light source at the detector it is going to work with? Is the purpose of this system to provide safety by stopping a machine when it is triggered, or is it for security, to send an alarm when something breaks a beam? The application matters a whole lot. We need to understand a lot more about this potential application.What is your electronic knowledge level and experience?

Then here is what I suggest you do. Purely for a home project and nothing industrial where life or limb may figure into things. I would go buy some of these or maybe some of these. All you need is a starter pack for a proof of concept and that takes care of the transmitter side. Then while you are at it buy some of these also so that takes care of the receiver end. Actually the plain sensors can also be bought so you don't need a few parts on the modules I linked. A Google of LASER Sensors or photo transistors should find some. I have played with some of those I linked to but have never really looked at the LASER dispersion over any distances so that is why I suggest buy a few and do a proof of concept. Get a few boards and drill mounting holes for the transmitters and receivers at precise intervals.Yes am sure
