Abstract
An optical engine for a LiDAR system comprises an analog detection channel comprising an avalanche photodiode (APD) optically coupled to light receiving optics and bias circuitry coupled to the APD and configured to adjust a bias set point (BSP) of the APD. Sensors sense disparate environmental factors that impact optical engine performance. Memory stores pre-established APD BSP data including a nominal APD BSP and pre-established dependence data characterizing the impact of disparate environmental factors on the nominal APD BSP. A controller generates, using sensor signals, in-field dependence data characterizing the impact the disparate environmental factors currently have on the nominal APD BSP, calculate an updated APD BSP using the in-field and pre-established dependence data, and shift the BSP of the APD from the nominal APD BSP to the updated APD BSP to enhance optical engine performance.
