There exist a wide range of sensors which capture this data, from tiny proximity sensors (which my research focuses on) to automotive LiDAR and benchtop lab-grade setups.

The quantized version of this signal is called the "transient histogram" or sometimes just "ToF histogram".
When the per-pixel FoV is wide, this histogram encodes rich information about the scene, as shown in this awesome animation by my labmate Sacha Jungerman (wisionlab.com/people/sacha...).

Direct ToF sensors send out a pulse of light, and measure the time it takes for that light to bounce off the scene and return.
Recently, a new class of these sensors have emerged that measure the intensity of returning light over very short (pico-to-nanosecond) timescales.
