Total internal reflection (tir) scanning device

A method of producing a field of view (FOV) in a frequency modulated continuous wave (FMCW) light detection and ranging (LIDAR) system, the method comprising:

• rotating a multi-sided scanner in a same direction at a plurality of different times to produce a plurality of rotational positions, wherein the multi-sided scanner comprises a plurality of sides;
• transmitting, at a first angle relative to a FOV window at a first rotational position of the multi-sided scanner, an optical beam towards a first side of the plurality of sides to cause a first portion of the optical beam to traverse the first side to produce a first adjusted beam transmitted within the multi-sided scanner towards a second side of the plurality of sides to produce a second adjusted beam, wherein a trajectory of the second adjusted beam traverses a third side of the plurality of sides to exit the multi-sided scanner to produce a first FOV portion;
• and
• transmitting, at the first angle at a second rotational position of the multi-sided scanner, the optical beam towards the first side to cause a second portion of the optical beam to traverse the first side to produce a third adjusted beam transmitted within the multi-sided scanner towards the second side to produce a fourth adjusted beam, wherein a trajectory of the fourth adjusted beam traverses the third side of the plurality of sides to exit the multi-sided scanner to produce a second FOV portion.

A frequency modulated continuous wave (FMCW) light detection and ranging (LIDAR) system, the system comprising:

• a multi-sided scanner comprising a plurality of sides;
• an optical source configured to:
• transmit, at a first angle relative to a field of view (FOV) window at a first rotational position of the multi-sided scanner, an optical beam towards a first side of the plurality of sides to cause a first portion of the optical beam to traverse the first side to produce a first adjusted beam transmitted within the multi-sided scanner towards a second side of the plurality of sides to produce a second adjusted beam, wherein a trajectory of the second adjusted beam traverses a third side of the plurality of sides to exit the multi-sided scanner to produce a first FOV portion;
• and
• transmit, at the first angle at a second rotational position of the multi-sided scanner, the optical beam towards the first side to cause a second portion of the optical beam to traverse the first side to produce a third adjusted beam transmitted within the multi-sided scanner towards the second side to produce a fourth adjusted beam, wherein a trajectory of the fourth adjusted beam traverses the third side of the plurality of sides to exit the multi-sided scanner to produce a second FOV portion;
• and
• a window positioned adjacent to the multi-sided scanner and configured to directly receive the second adjusted beam to form the first FOV portion and the second FOV portion.
