I need to get a clear level of words and graphics ..
The laser is for professional use ..
OK - so pro use for the gear. That`s puts the gear you want to use into another ballpark altogether. I understand that you are quite new to this laserthing, and we all have been there.
Just some bits and word of advice along the way.
There have been discussed some entry software and DAC solutions in this thread. When jumping into the pro-division, the requirements are quite a bit different, and the pricetag of the gear you need are much higher than ISHOW and Spaghetti.
You have not given us the specifications of the actual laser projector that you are going to use, and that is just an important piece as the software and DAC.
The galvos (motors for the mirrors) have to be able to reproduce what the software and DAC are sending through the cable.
The lasermodules including the optics have to have the power and quality required for the job. My first chinese projector had a nice 3mm 1,5 mrad 532nm module (Green) - a 4mm 2mrad 450nm module (Blue) and a 6mm 3mrad 638nm (red) module.
The result was a really fat red beam with a tiny green line in the middle when projecting into a wall more than 5 meters away. Disapointed - yes, because in my mind lasers was pencil thin light travelling perfectly pararel. Sadly that is not the case.
To get to all three colors the same thickness and not expanding at short distance, thats the trick, and what most of the members here at PL are aiming for. (modulevise).
My advise for now is to play around - and read as much as you can here on PL. Accept that lasergear are expensive, ask here when in doubt, be specific in what you actually want to achieve, and my promise to you are a lot of help from the members here at PL.
The total sum of mistakes been done by all PL members, and all the knowlage to fix all of the mistakes are either inside PL or at our fingertips.
