iToF vs dToF: O que é melhor para medições a laser?

Q: What Is iToF (Indirect Time-of-Flight)?

How iToF Works iToF measures distance by modulating the emitted laser light and analyzing the phase shift of the returning signal. This phase difference is used to calculate the travel time of light, allowing for precise distance measurement. Key Features of iToF Sensors High measurement accuracy for short to mid-range distances (<10m). Works well in controlled environments like indoor automation, AR/VR, and facial recognition. More affordable than dToF but can be affected by ambient light and reflective surfaces.

Q: What Is dToF (Direct Time-of-Flight)?

How dToF Works dToF directly measures the time it takes for a laser pulse to travel to a target and reflect back. By calculating the light travel time, it determines the precise distance. Key Features of dToF Sensors Ideal for long-range distance measurement (>10m to several hundred meters). Works well in outdoor environments, robotics, automotive LiDAR, and industrial automation. Better resistance to ambient light interference and reflective surfaces. Requires high-speed circuits, making it more expensive than iToF sensors.
