The ranging sequence of OAK-FFC-TOF-33D

zenglu

1.May I ask if there is a detailed documentation explanation about the ranging principle of OAK-FFC-TOF-33D? Because I need to know the ranging sequence of tof. The ranging sequence here refers to: measuring the distance of pixels in the same frame, the order of the distances of the measured pixels, such as from top to bottom and then from left to right.

2. Does OAK-FFC-TOF-33D emit infrared rays and then use phase laser ranging (iTOF)?

3. Is tof ranging an instantaneous measurement? This means that for the same frame of ranging data, the ranging of the first pixel and the last pixel is completed at the same moment. Here, there is no motion distortion. Don't we need to consider the motion distortion caused by the movement of the carrier?

thanks

Pixel readout occurs row by row, but at a very high speed — with a maximum exposure time of about 750 microseconds. Therefore, motion distortion is minimal and typically not an issue.

Yes, the OAK-FFC-TOF-33D emits 940 nm infrared light and uses indirect Time-of-Flight (iToF) phase-based ranging.

As mentioned above, the measurement is effectively instantaneous for most use cases. While readout happens sequentially by rows, the very short exposure time ensures that motion distortion is negligible.
