Scanning assembly for a detection system

A scanning assembly for a detection system for a vehicle, comprising:

• a scanning fixture including a mirror attached to a first pivot for rotation of the mirror around a first axis, rotation of the mirror around the first axis changing a field of view of the detection system to perform an azimuth scan of a surrounding environment;
• a central member attaching a second pivot to the first pivot for rotation of the mirror around a second axis, the second axis orthogonal to the first axis, rotation of the mirror around the second axis changing the field of view of the detection system to perform an elevation scan of the surrounding environment;
• a base attached to the second pivot and the vehicle;
• a first permanent magnet fixed on a first side of the scanning fixture;
• a second permanent magnet fixed on a second side of the scanning fixture opposite the first side, wherein the first pivot is between the first and second sides of the scanning fixture;
• a first electromagnet attached to the base and configured to apply a force to the first permanent magnet to selectively push or pull the mirror to change the field of view via rotation of the first pivot to perform the azimuth scan;
• a second electromagnet attached to the base and configured to apply a force to the second permanent magnet to selectively push or pull the mirror to change the field of view via rotation of the first pivot to perform the azimuth scan;
• a third permanent magnet fixed to the central member;
• and
• a third electromagnet attached to the base and configured to apply a force to the third permanent magnet to selectively push or pull the central member to change the field of view via rotation of the second pivot to perform the elevation scan,
• wherein:
• the mirror is configured to operate in a resonant mode such that the mirror oscillates around the first axis at a first oscillation frequency and the mirror oscillates around the second axis at a second oscillation frequency, a ratio of the first oscillation frequency to the second oscillation frequency being irrational;
• the first pivot includes a first central cylinder disposed between first and second cylinder ends;
• the first central cylinder includes a first central arcuate member extending into the first and second cylinder ends, the first central arcuate member immovably fixed to the first central cylinder and rotatable within the first and second cylinder ends around the first axis;
• a first end arcuate member immovably fixed to the first and second cylinder ends, the first end arcuate member rotatable within the first central cylinder around the first axis;
• a first flexible sheet attaching the first end arcuate member to the first central arcuate member, the first flexible sheet elongated along the first axis such that rotation of the first pivot around the first axis causes the first flexible sheet to bend in torsion, the first flexible sheet forming a first plane and resisting movement of the first central cylinder with respect to the first and second cylinder ends along the first plane;
• and
• a second flexible sheet attaching the first central arcuate member to the first end arcuate member, the second flexible sheet elongated along the first axis such that rotation of the first pivot around the first axis causes the second flexible sheet to bend in torsion, the second flexible sheet forming a second plane and resisting movement of the first central cylinder with respect to the first and second cylinder ends along the second plane.
