Dual emitting co-axial LiDAR system with zero blind zone

A dual emitting co axial light detection and ranging (LiDAR) system comprising:

• a first light source configured to provide a first light beam;
• a second light source configured to provide a second light beam;
• a first light detector configured to detect return light formed by scattering the first light beam by a target in a field of view;
• one or more optical elements configured to transmit the first light beam from the first light source to the target in the field of view and to direct the return light to the first light detector, wherein the one or more optical elements are disposed outside of a light path of the second light beam from the second light source;
• and wherein the first light detector is configured to detect internally-reflected light formed by partially reflecting the first light beam by at least one of the one or more optical elements;
• a second light detector configured to detect return light formed from the second light beam;
• and
• control circuitry configured to mitigate a blind-zone effect resulting from the internally-reflected light detected by the first light detector, based on the detected return light formed from the second light beam.
