Abstract
An illustrative example embodiment of a device for detecting rain or a substance on a windshield includes at least one radiation source, an internal reflection sensor situated to detect at least some of a first portion of the radiation that reflects from the windshield. The internal reflection sensor provides a first output that has a characteristic that differs based on whether at least one raindrop is on the windshield. A scattered reflection sensor is situated to detect at least some of a second portion of the radiation reflecting from rain near the windshield or a substance on the windshield. The scattered reflection sensor provides a second output indicative of an amount of radiation incident on the scattered reflection sensor. A processor is configured to determine a condition of the windshield based on the first output and the second output.
