I am a using a mirror to reflect an image at an angle of incidence of 10 degrees. The mirror is also at an angle of incidence of approximately 30 degrees from the viewer and it creates undesired reflections when looking at the mirror. Here is a diagram illustrating the situation.
I am looking for an optical apparatus that can block visible light at large angles of incidence but at small angles of incidence let light pass through?
For example, I tried using a privacy screen like the ones used on smartphone or computer monitors. The privacy screen uses micro louvers to block light at large angles. I placed the privacy screen on top of the mirror. However the reflection was very diffuse and not usable.
