Time of Flight 3D Sensing and Imaging: detectors, readout circuits and data processing
In the past few years we have assisted to a tremendous increase of the number of applications requiring highly sophisticated electronic systems capable of taking autonomous decisions during the interaction with complex environments and scenarios.
Depth sensors represent a fundamental enabling technology for such applications, allowing to reconstruct a complete 3D model of the surrounding environment, thus increasing the reliability and robustness of automatic objects classification.
Several depth-sensing technologies are available, and it is becoming more and more evident that the optimal solution relies on a clever combination and optimization of multiple techniques, through a careful optimization at system level of a multitude of parameters.
The main goal of this talk is to provide an in-depth overview of state-of-the-art ToF detectors technologies focusing on the main advantages and disadvantages of the two key competing detector classes, i.e. photo-demodulators or SPADs, and their natural implementation in indirect-/direct-ToF systems through key examples from commercial and academic implementations.
