I have read at least two threads and watched an online video about which angle is better for a V shaped platen design, and problems had with reflections. I wanted to learn more about the topic, regardless of the scanner build-design and found these resources, which might also be of interest to others:
1. Optics: Light, Color, and Their Uses Educator Guide
https://www.nasa.gov/audience/foreducat ... Guide.html
Of which: Reflection of Light With Two Plane Mirrors - Double Mirrors Placed at a Number of Angles might be of interest for those with V-shaped designs.

2. Ray Optics Simulator (by github user rictu288)
https://ricktu288.github.io/ray-optics/simulator/ Which will let you simulate light sources, positions, etc.
P.S. I wasn't sure where to post it, so it ended up in here.
Daniel Reetz, the founder of the DIY Book Scanner community, has recently started making videos of prototyping and shop tips. If you are tinkering with a book scanner (or any other project) in your home shop, these tips will come in handy. https://www.youtube.com/channel/UCn0gq8 ... g_8K1nfInQ
