Pulsar

The structured-light projector system Pulsar combines precision, speed, and flexibility and is exceptionally well-suited for the use in optical 3D measurement and object recognition.

Optical 3D measuring and object recognition has many advantages, especially for measuring and inspecting complex 3D geometries. Especially in an industrial environment, the Pulsar system developed by SAC can leverage the advantages of the highly precise, areal scanning of 3D contours by means of structured light.

Pulsar combines high speed with large measuring volumes, which makes it ideal for industrial inspection tasks such as completeness, shape deviation, position of components, planarity control, and volume measurement.

An intelligent evaluation logic determines the measured values for the reliable evaluation of the inspection object from the 3D data. The graphical teach-in tool enables you to adjust the system to new types or to change the inspection tolerances in an instant. All measured values can be logged and statistically evaluated. This makes the production process transparent, and process fluctuations can be identified and localized quickly, making costly serial defects a thing of the past.

Technology & Functional Principle

Structured-light scanners are perfect for scanning planar or curved, diffusely reflective surfaces. In the process, an LED projector projects stripes onto the inspection object (a combination of the phase-shift and gray-code methods). This stripe pattern is shifted electronically and captured by a CCD grayscale camera in a defined angle. By capturing single images of the stripe pattern, which is distorted by the inspection object, a highly precise 3D image of the inspection object is created.

Details
