Using time-of-flight technology, STMicroelectronics developed a highly accurate optical range-finding FlightSense module that offers designers superior distance-measurement capability. Expecting future applications in Mobile Phones, Consumer White Goods, and Industrial Applications, the sensing technology has already been incorporated in LG G3 smartphone’s camera auto-focus assist.
In contrast to conventional sensors that can only report reflected signal levels and not absolute distance, the FlightSense proximity sensor provides accurate distance sensing by measuring the time for emitted light to reflect back from the target.
Offered in a 4.8mm x 2.8mm x 1.0mm optical LGA12 package, the VL6180X combines FlightSense proximity sensing with an ambient-light sensor (ALS) and supports basic gesture recognition to simplify the user-interface design.
To simplify evaluation and support application development, ST offers the VL6180X Explorer evaluation kit.
