Projector Pixel Redirection Using Phase-Only Spatial Light Modulator

TL;DR

This paper presents a method to improve pixel density uniformity in projection mapping onto non-planar surfaces by redirecting projected rays with a phase-only spatial light modulator, enhancing spatial resolution consistency.

Contribution

The novel approach uses a phase-only spatial light modulator to achieve pixel redirection, addressing uneven pixel density in projection mapping on complex surfaces.

Findings

Improved pixel density uniformity on non-planar surfaces

Enhanced local spatial resolution in projection mapping

Validated effectiveness through experimental confirmation

Abstract

In projection mapping from a projector to a non-planar surface, the pixel density on the surface becomes uneven. This causes the critical problem of local spatial resolution degradation. We confirmed that the pixel density uniformity on the surface was improved by redirecting projected rays using a phase-only spatial light modulator.
