3DEO, Inc. @3deolidar.bsky.social · 03/03/2026Geiger-mode vs. linear-mode lidar — what’s the difference? Linear-mode lidar sweeps a pulsing laser beam back and forth over an area of interest, requiring about 300 photons to get above noise and identify returns. 100 0
3DEO, Inc. @3deolidar.bsky.social · 03/03/2026Geiger-mode lidar is similar, but the laser illuminates a GM camera which requires only about 20 photons per return to reliably identify a surface. Using a Geiger-mode camera for optical imaging instead of a narrow laser beam enables agile geo-referenced scanning. 100 0
3DEO, Inc. @3deolidar.bsky.social · 03/03/2026Agile geo-referenced scanning is very flexible, allowing pulses and scans to be aggregated together without photons coming from the same laser pulse. Increased photon sensitivity combined with agile scanning means flying higher and collecting faster, without loosing data quality 000 0
