Broadcom - smart sensing with innovative optical technology

Broadcom has a range of unique optical sensors for smart sensing in medical, industrial, automotive, biomedical and scientific research applications.

The range of products includes Time-of-Flight (ToF) sensors for distance & motion measurement and IR LEDs for light curtains for sensing applications.

Time-of-Flight 3D multi-pixel sensor family for distance and motion measurement

Optical distance measurement has a variety of uses in industrial applications. For years, Time-of-Flight (ToF) sensors have been used in measurement and monitoring tasks in factory automation and production. There have been new use cases for optical distance measurement that require precise 3D information and extended range like Drones or AMR/AGV. 

Multi-pixel distance and motion measurement sensor IC technology, based on the optical Time-of-Flight principle.
