Hello,
I'm working with an automotive headlamp and I was asked to simulate a projection of this lamp onto a wall 25 feet apart. I know I need to use a Fresnel lens as a collector to achieve this, however I have many questions:
1. How should I choose the right Fresnel lens?
2. I need to project a pattern over the Fresnel onto a white screen in a 35 " long table, so I need to decrease the image, can I do this with a collector?
3. Where can I find theory to justify my "calculations", I've tried to search for information on fresnel lenses design but I've had not luck. Can someone point me out in the right direction.
Any information will be appreciated, thank you!
