A system includes an optical window, and an illuminator and a first light sensor deployed on a same side of the optical window. The system further includes a second light sensor on another side of the optical window. The system further includes a computer including a processor and memory. The memory includes instructions such that the processor is programmed to identify an obstruction on the optical window upon the first light sensor reporting first data from the illuminator that is above an expected threshold. The expected threshold is based on second data from the second light sensor.
