Retired Engineer Investigating Plasma‑Based Optical Phase Control

How did you find PF?

Hello everyone,My name is Ronald Coleman, and I’m a retired engineer and inventor based in Temescal Valley, California. I spent many years working in advanced imaging and materials environments, and I’m now focused on exploring a new optical concept involving thin‑film structures and micro‑plasmas.

I’m here to learn from the community, ask high‑level physics questions, and get feedback from people experienced in photonics, plasma physics, and wavefront control. I’m not sharing any proprietary implementation details — just looking to understand feasibility and connect with others who enjoy pushing the boundaries of optical engineering.

I’m especially interested in:

• refractive‑index modulation mechanisms
• plasma–optics interactions
• phase control in thin‑film structures
• high‑speed modulation (MHz range)
• wavefront shaping for display applications

I’m looking forward to contributing where I can and learning from the expertise here.Thanks for having me.

— Ronald
