Our single-photon counting 3d Lidar can be much more efficient than conventional lidars, which often use hundreds or even thousands of received photons to make a single range measurement. The high efficiency allows much greater spatial resolution and/or spatial coverage in generating topographic maps.
The development of this technology, led by Sigma Space Chief Scientist Dr. John Degnan, has been sponsored over the past decade by NASA and the USAF, and has already shown its potential value in the measurements of ice sheet thickness and biomass in support of global climate change studies.
