brushless motor, and Williams and Messori
also developed a “spherical scanning kit”
that mounts the unit on a servo, oriented
at 90° to the brushless motor, so that it can
record data in three dimensions.
Grau, too, was able to design a version
of his sensor that offered a fuller, 3D view,
by adding another motor. In both cases, the
results are limited by the frame rate of the
unit; if you’re spinning it at 10Hz (the max
speed for Scanse’s device) and recording
500 samples per second (the max for
PulsedLight’s Lidar-Lite), you’ve just cut
that by whatever your rotations per second
are on the Y axis: You only get to see the
full picture once ...
