How far should the laser be aimed during the sight alignment test on a LIDAR for best results?

The recommended distance for aiming the laser during the sight alignment test on a LIDAR system is 100 feet. This distance strikes a balance by allowing the operator to effectively evaluate the accuracy and alignment of the LIDAR. At 100 feet, the alignment can simulate real-world conditions, ensuring that the LIDAR is properly calibrated for typical enforcement scenarios where measurements are taken.

This distance is significant because at shorter distances, the LIDAR may not exhibit as much of the angular deviation that could occur at operational ranges, potentially giving a false sense of accuracy. Conversely, at distances much greater than 100 feet, environmental factors such as atmospheric distortion can affect the accuracy and clarity of the laser's alignment.

Setting the test at this standard distance helps ensure that the laser energy is sufficient to make reliable contact with the target while remaining manageable and measurable, which is crucial for maintaining the integrity and reliability of measurements obtained by the LIDAR device in practical use.
