Direct Time-of-Flight (dToF) image sensors provide high-accuracy depth measurement by emitting a pulse of light—typically from a laser or LED—and precisely calculating the time it takes for the reflected light to return. Unlike indirect Time-of-Flight (iToF) sensors, which rely on phase shifts to estimate distance, dToF sensors directly measure the time delay, making them highly effective for long-range applications and outdoor environments where ambient light interference can be a challenge.

Utilizing advanced single-photon avalanche diode (SPAD) technology, dToF sensors can detect even minimal amounts of reflected light, enabling reliable depth sensing in low-light conditions. Their ability to capture X, Y, and Z-axis data allows for robust 3D imaging, making them indispensable in applications requiring object recognition, obstacle detection, and spatial mapping.

The use of dToF technology in industrial cameras is particularly beneficial, as it allows these systems to capture critical depth information for quality inspection, spatial awareness, and robotic control. With real-time depth measurements, these sensors support the automation of tasks such as material handling, assembly line monitoring, and hazard detection.
