A topographical measurement system may include a tactile sensor using a contained fluid as an imaging medium.

Fluid tactile sensors

Retrographic sensor cartridge

Continuous measurement of surfaces larger than a sensor is facilitated by the use of a sensor matrix of a clear elastomer and a reflective surface that scrolls, rolls, or otherwise moves over a target surface. A variety of web materials, camera configurations, and handling systems are described to achieve continuous three-dimensional measurement in this context.

Continuous contact-based three-dimensional measurement

This disclosure provides systems, devices, and methods for capturing and measuring surface topography. This disclosure provides a high resolution retrographic sensor comprising a volume of elastomer and a thin, opaque reflective membrane. The reflective membrane is arranged to conform to a specimen that contacts it. The disclosure provides a high resolution visualization system comprising the retrographic sensor and an illumination source. Also provided are high resolution measurement systems comprising the retrographic sensor, an illumination source, an imaging device, and a processing component.
