"pixels" and "field of view" along with the comparatively terrible "20 Hz" rate strongly hints to me (a total layman, admittedly) that these are full 2D frames at 20 Hz, not single pixel samples at 20 Hz. The thought that it would take a full 45ms to sample a single pixel sounds absurd, even for research tech in this area when industry standard is pushing 100 kHz. A 2D surface sampling, say, 200x200 = 20k pixels per frame * 20Hz sounds much more reasonable. If it was only 1D, it would be utterly unfit for navigation if you just scatter a few of them around on the vehicle in fixed locations like their marketing suggests. You can't replace a spinning roof-mounted lidar with just a few fixed 1D sensors. The spinning lidar gets something on the order of one sample per degree, right? To even come close to replacing that with fixed 1D sensors you'd need on the order of 360 of them around the vehicle, and their marketing doesn't sound like that they expect you to use anywhere near that many.
