z-Snapper 3-D Camera To capture 3-D data with speed, resolution and ease, ViaLux GmbH of Chemnitz, Germany, designed the z-Snapper camera for machine vision applications.

The instrument encompasses the company's newly developed high-speed electronics (ALP), Texas Instruments' digital micromirror chip-set technology, a fast digital CCD, an LED-based projector, and proprietary algorithms and software for phase-code readings. The camera's 330,000 data points per measurement can reveal small object features with high reliability.

It provides full-field 3-D surface data with high resolution after 1/25-s exposure, can be implemented in fast, online testing systems, and can record living objects. The mobile device can be battery-powered for outdoor applications. It does not produce heat, and therefore does not require a fan, and is enclosed in a dust-protective housing for industrial use.

The ALP controller interfaces via USB, and the digital camera plugs into a FireWire port, enabling the z-Snapper to connect to standard laptops and yielding a high degree of mobility.

Besides machine vision functions such as shape testing and monitoring the presence of parts in low contrast, applications include security, for recording 3-D biometric data, and medicine, for cancer screening and for sensing the shape and position of parts of the body.
