Abstract:
GELSIGHT, INC. is a startup commercializing a unique
imaging technology invented at MIT. The technology uses
an elastomeric pad that conforms to any surface and enables
3D measurement of precise surface topography. Dr. Kimo
Johnson, co-founder of the company and co-inventor of the
technology, spoke with our team to explain how measurements
of 3D surface topography can be used for shot-peened
surface characterization.
What was the concept or challenge that led to the founding
of GelSight?
Johnson: The driving concept behind the technology was to
turn tactile interaction into an image. Our soft elastomeric
pad is similar to human skin in that it deforms when it presses
against objects. The early research on the technology demonstrated
that it could be used to measure detailed 3D surface
geometry of any material, which has broad applications across
many industries.
