Cheaper, Faster, Better- Trumper on Instantaneous Phase Shifting Deflectometry

Posted on April 17, 2017 by Logan Graves

This week we speak with Isaac Trumper about his recent paper covering the novel instantaneous phase deflectometry he created. Using an iPhone, Isaac was able to take instantaneous measurements of a test surface with nm level accuracy. We discuss how this was done, what this means for how mirrors can be measures, and how it stacks up to the commercial competitors. Continue reading →
