A method for detecting a fault condition in a light detection and ranging transmitter includes generating a control signal that comprises an address and desired drive voltage and current information for a laser in a laser array. A drive signal is generated for the laser in the laser array in response to the generated control signal and applied to a contact associated with that address of the laser array, thereby energizing the laser at a desired output power for a desired time. A determination is made on whether the drive signal has a parameter with a value that is outside a threshold range for eye safety. The address and the fault condition is stored if the parameter has the value outside the threshold range for eye safety and reported to a host that takes an action on the LiDAR transmitter in response to the fault condition.
