Understanding Indirect Time-of-Flight Depth Sensing

The microsoft kinect does 3 frequency measurements to get the higher distance precision of higher modulation frequencies and to extend the maximum distance so the phase wrapping (aliasing) can be solved.

Based on some Microsoft patent filings and other research papers I wrote a short article on possible phase unwrapping methods on iToF sensors, https://medium.com/chronoptics-time-of-flight/phase-wrapping...

Fantastic article!!! They definitely need your animations, it's way more intuitive.

Thanks, got any references to how the surveying equipment de-aliasing method worked?

I don’t unfortunately. I was there doing an information security assessment and the guy I was working with was one of the product engineers. When I wrapped my work we spent another hour or two just talking about their products and how they worked.
