The brilliant people at MIT (Massachusetts Institute of Technology) are pushing the envelope again. This time it involves needing only one photon for each pixel in a depth map image – incredible. As reported in MIT News this technology could have a dramatic impact on the design of lidar sensors.
A conventional lidar system requires about 100 times as many photons to make depth estimates of similar accuracy under comparable conditions. The new system could yield substantial savings in energy and time — which are at a premium in autonomous vehicles trying to avoid collisions.
