# Pulfrich's stereo curtain

## TL;DR

This paper introduces a new visual motion stimulus using longitudinal waves to create the illusion of 3D wave movement.

## Contribution

A novel method for perceiving stereoscopic travelling waves using a phased array of oscillations.

## Key findings

- Longitudinal waves can be used to create a stereoscopic visual effect.
- The phased array of oscillations supports the perception of 3D wave motion.

## Abstract

Travelling longitudinal waves provide a novel visual motion stimulus that supports the perception of stereoscopic travelling waves from a phased array of sinusoidal oscillations.
