Claim 0:
1. A method comprising:
emitting light signals having a first emission power from a first plurality of light emitters within a light detection and ranging (lidar) device during a first firing cycle of a firing sequence;
listening, during the first firing cycle by each light detector of the lidar device that is associated with the first plurality of light emitters, for light signals reflected from a surrounding environment;
emitting one or more light signals having a second emission power from one or more light emitters within the first plurality of light emitters during a second firing cycle of the firing sequence, wherein the second emission power is less than the first emission power;
emitting light signals having the first emission power from a second plurality of light emitters within the lidar device during the second firing cycle, wherein the second plurality of light emitters comprises the light emitters within the first plurality of light emitters that are not emitting light signals having the second emission power during the second firing cycle;
listening, during the second firing cycle by each light detector of the lidar device that is associated with the first plurality of light emitters, for light signals from the surrounding environment; and
identifying whether interference is influencing measurements made by the lidar device, wherein identifying whether interference is influencing measurements made by the lidar device comprises determining, for each light detector of the lidar device that is associated with the first plurality of light emitters, whether any light signals detected during the second firing cycle correspond to the first emission power or the second emission power.
