Well, not quite. But close.
In any event, for those curious about optical sensors... feel free to read up on them
Very interesting, thank you!
Do you know how (the physical principle) a laser can measure speed?
Pitot Tube is used for measuring speed in F1.
A laser can measure speed with two different methods:
1) The instrument shoot a "ray" to an object and it analyzes the frequency of the ray that "returns" to the instrument. It uses Doppler Effect: the frequency of the ray that returns changes depending of the speed of the object.
2) The instrument measures how long a ray shot to an object does take to "return" to the instrument. It uses the kinematics formula of uniform motion: d=c*t
c= speed of light
t= time for the "returning" of the ray
