This Youtube video shows Heliotis presentation of its 3D camera for industrial applications with micron resolution, delivered by Christian Lotto. The camera features Heliotis smart-pixel custom designed sensor with 300x300 resolution and 5000 fps speed. Each pixel provides quadrature demodulation of interferometric pattern, envelope extraction, low-pass filtering and downsampling - sort of lock-in amplifier in each pixel.
The pdf version of the presentation is available here.
Very nice!
