Microgeometry Capture using an Elastomeric Sensor
"Our microgeometry capture system consists of an elastomeric sensor and a high-magnification camera (a).
The retrographic sensor replaces the BRDF of the subject with its own (b)
allowing microscopic geometry (in this case, human skin) to be accurately captured (c)
The same principles can be applied to a portable system (d) that can measure surface detail rapidly and easily; again human skin (e)."
Example geometry measured with the bench and portable configurations.
