Direct vs. Indirect Time-of-Flight: Choosing the Right 3D Sensor
Time-of-Flight (ToF) 3D sensing technologies, Direct (dToF) and Indirect (iToF), differ fundamentally in how they measure light travel time. dToF uses precise pulse timing for long range and outdoor robustness, while iToF employs phase shift for high resolution in shorter-range applications.
