Abstract
A light detection and ranging system is provided. The light detection and ranging system includes a LIDAR scanning mirror; a processor configured to control the LIDAR scanning mirror; a first position sensor configured to determine a first position and a second position sensor configured to detect a second position of the LIDAR scanning mirror. The processor is configured to determine whether an eye-safety criterion is met based on the first position and the second position, and control light output of the LIDAR system based on whether the eye-safety criterion is met.
Claims23
A light detection and ranging (LIDAR) system, comprising:
- a LIDAR scanning mirror;
- a processor configured to control the LIDAR scanning mirror;
- a first position sensor configured to determine a first position of the LIDAR scanning mirror and a second position sensor configured to detect a second position of the LIDAR scanning mirror;
- the processor configured to
- determine whether an eye-safety criterion is met based on the first position and the second position, and
- control light output of the LIDAR system based on whether the eye-safety criterion is met.
A light detection and ranging (LIDAR) system, comprising:
- an optical amplifier to amplify light provided by a light source to generate output light of the LIDAR system having an output light power;
- a processor configured to control the optical amplifier;
- an electrical sensor configured to detect a current applied to the optical amplifier to control an amplification of the optical amplifier, wherein the detected current corresponds to the output light power;
- and
- an optical sensor configured to detect light comprising at least one light from the light source and the generated output light;
- the processor configured to control the output light power of the output light based on the detected current and the detected light whether an eye-safety criterion is met.
A non-transitory computer readable medium having instructions stored therein that, when executed by one or more processors, cause the one or more processors to
- determine sensor signals of:
- at least a first position sensor detecting a first position of a LIDAR scanning component and a second position sensor detecting a second position of the LIDAR scanning component, and/or
- an electrical sensor configured to detect an electrical current applied to an optical amplifier of the LIDAR system that controls the amplification of the optical amplifier and/or an optical sensor configured to detect light including at least one of the light from a light source of the LIDAR system or generated output light of the LIDAR system;
- compare the determined signals of the first and second sensors, the electrical and/or the optical sensors with a predefined threshold value corresponding to an eye safety criterion;
- and
- reduce a power of one or more components of the LIDAR system in case the determined signals exceed the predefined threshold value.
