This microscope uses touch

Summary by Krater

Steve Mould tests a unique handheld optical instrument called the GelSight that uses a deformable gel pad and six light sources to generate 3D surface scans without color or transparency data, concluding with an advertisement for the Jane Street AMP summer program.

Answers: How does the GelSight microscope work to create 3D surface models?

• photometric stereo
• surface metrology
• 3D surface scanning
• optical illusions
• gel pad imaging

What it concludes

• The GelSight device uses six different light sources and photometric stereo to generate 3D models of object surfaces accurate to plus or minus four microns.
• Removing color and transparency information helps algorithms accurately detect surface slope and create 3D topography without being tricked by lighting reflections.
• The Jane Street Academy of Math and Programming is a completely free five-week summer program in New York for high school graduates with an interest in math and computer science.
