Heliotis White Light Interferometric 3D Sensor

Heliotis releases more info about its Series 4 while light interferometric 3D sensor:

"It’s basis is a CMOS 2D array in which each individual pixel picks up and processes the optical signal in parallel. In this SmartPixel concept each pixel has an electronic circuit for real-time image processing.

The light reflected by the sample is combined with a reference signal. This results in an interferometric signal from which the desired depth information can be derived mathematically. The system works non-invasively and non-contact in a wide range of objects and materials with a spatial resolution of microns.

The new generation of WLI sensors has been developed from scratch. We put in over 10 years of experience from Series 1, 2 and 3."

Thanks to TL for the info!
