The final version of the Kinect, called "Azure Kinect" was based around the ADSD3100 time-of-flight sensor from Analog Devices. The Kinect has since been abandoned by Microsoft. However, Analog offers a match-box sized module ADTF3175 integrating the ADSD3100-sensor, optics and VCSEL (940nm laser illuminator) with MIPI 4-lanes output. A devkit [1] also exist and is available from mouser, digikey, et al.
I got the dev kit and looking for someone to team up for commercialization of the potential of one megapixel time of flight camera. There will be probably nothing better for a long time due to complex pixel analog circuitry design. It’s very interesting sensor at the moment.
You can also buy a rebranded Azure Kinect called the Orbbec Femto Bolt. Like the original Azure Kinect, the quality is amazing and blows the Realsenses out of the water.
