a first set of one or more light receivers, coupled to the first fixed portion of the vehicle, and configured to receive portions of the emitted light reflected from the first measuring area;
wherein the first propulsion portion of the vehicle is a portion of the vehicle that rotates about a first axis to cause the vehicle to be propelled in movement;
wherein a first light transmitter of the first set of one or more light transmitters is arranged relative to a first mirror of the first plurality of mirrors in order to reflect light emissions from the first light transmitter off of the first mirror at a first angle relative to the first axis;
wherein the first light transmitter is arranged relative to a second mirror of the first plurality of mirrors in order to reflect light emissions from the first light transmitter off of the second mirror at a second angle relative to the first axis, the first angle being different than the second angle.

2. The remote sensing system of claim 1 ,
wherein the first propulsion portion of the vehicle comprises a motor configured to propel the vehicle.

3. The remote sensing system of claim 2 ,
wherein the motor comprises at least one of an outrunner motor, an inrunner motor, a hollow bore motor, and a gas powered motor.

wherein the first propulsion portion of the vehicle comprises at least one of: a rotor, an axle, and a wheel.

5. The remote sensing system of claim 1 ,
wherein the first fixed portion of the vehicle is a portion of the vehicle that does not rotate in order to cause the vehicle to be propelled in movement.

6. The remote sensing system of claim 1 ,
wherein a first mirror of the first plurality of mirrors is fixed at a first angle relative to the first axis;
wherein a second mirror of the first plurality of mirrors is fixed at a second angle relative to the first axis, axis; and
wherein the first angle is different than the second angle.

7. The remote sensing system of claim 6 ,
