What is a TOF Camera? - TOF Camera Basics


Time-of-Flight (TOF) cameras are advanced depth sensing devices that calculate distance by measuring the time it takes for light to travel from the sensor to the subject and back. At Suzhou Guanshi Intelligence Technology Co., Ltd. (SGI), we specialize in developing high-performance TOF camera modules that emit infrared pulses or modulated light and perform precise timing measurements to generate accurate 3D point clouds in real time.
TOF technology represents a breakthrough in 3D sensing, enabling applications that require precise depth information in various lighting conditions and environments. Our TOF cameras provide reliable depth sensing solutions for robotics, smart homes, healthcare, and industrial applications.
