LIDAR
What is LIDAR?Light Detection and Ranging.
What does that mean?Light used to determine distance to an object.
How does it work?Any Guesses?
Time Of Flight
We know some things Velocity of light Time that signal is sent Time that signal is received
Distance from TOF
Return @ t = 1ns
Transceiver Object
Signal sent @ t = 0 Impact @ t =
1ns
Transceiver
ObjectSignal received @
t=3ns
Distance = c x t/2= 3x10^8 x 1.5 x10^-9
LIDAR Applications
Remote Sensing

Autonomous Vehicle Guidance
Why is our LIDAR so cool?
64 Lasers calculating distance and intensity
32 upper block lasers32 lower block lasersGives us 28˚ VFOV
And……
It Spins!
Why is that cool?
360 HFOV
