Manufacturing + Automation
Machine vision enables greater automation of manufacturing and warehouse operations. Liquid crystal polarization grating beam steering has proven to increase range, resolution, and field of view of compact time-of-flight cameras, lidars, and narrowband passive cameras, all while being robust to dirty, high-vibration environments.
Compact, Non-mechanical Beam Steering Enhances Capabilities of Existing Low-cost Sensors
Manufacturing and warehouse robotics may use depth-sensing imagery for navigation, collision avoidance, defect monitoring, and materials handling. Such applications can span a wide range of distance, resolution, and depth accuracy requirements that are difficult to achieve with any one sensor technology. Meanwhile, solutions in this industry require low operating costs with minimal down-time while operating in environments that are frequently dirty and high in mechanical shocks and vibrations.
At BNS, we have demonstrated that beam steering devices using liquid crystal polarization gratings (LCPGs) can enhance imaging performance in these sensors. Specifically, the integration of non-mechanical, digital beam steering of the field of view enables the use of wide-aperture, narrow-angle illumination and collection optics, boosting angular resolution and significantly improving signal-to-noise ratio. The steering then permits retention of a large scanned field of view for greater situational awareness.
Our advanced technologies are compatible with existing industrial processes and capabilities used for consumer markets, easing the transition to high-volume production.
