Understanding ToF Sensors: Principles and Applications
Time-of-Flight (ToF) sensors measure the distance between the sensor and an object by calculating the time it takes for a light signal to travel to the object and back, enabling precise depth mapping and 3D imaging. Infrared sensors emit infrared light and detect reflections to sense proximity, but ToF sensors provide greater accuracy and range due to active light pulsing and time measurement. Mobile devices leverage ToF technology for advanced applications like augmented reality, facial recognition, and gesture control, surpassing traditional infrared sensors in performance and versatility.
Infrared Sensor vs ToF Sensor: Key Technical Differences
Infrared sensors emit infrared light and measure the reflected signal to detect objects based on heat signatures or proximity, offering simple and energy-efficient solutions for mobile devices. ToF (Time-of-Flight) sensors calculate the distance by measuring the time taken for a light pulse to travel to an object and back, enabling precise 3D depth mapping and improved spatial awareness. Infrared sensors typically perform better in low-light conditions with limited range, while ToF sensors excel in accuracy and range but demand higher power consumption and processing capabilities.
