1. A vehicle comprising:
- a vehicle frame;
an optical device mounted on said frame and including a lens having an exterior surface exposed to ambient air surrounding said vehicle;
a first temperature sensor sensing air temperature of said ambient air surrounding the vehicle;
a second temperature sensor sensing a temperature of said lens;
a humidity sensor sensing moisture content of air proximal said lens; and
an exhaust directing a gas at said lens exterior surface in response to said ambient air temperature sensed by said first temperature sensor, said temperature of said lens sensed by said second temperature sensor, and said moisture content sensed by said humidity sensor.

Abstract
A vehicle includes a vehicle frame and an optical device mounted on the vehicle frame. A first temperature sensor senses ambient air temperature surrounding the vehicle frame, a second temperature sensor senses a temperature of a lens of the optical device, and a humidity sensor senses moisture content of air proximal to the lens. An exhaust directs gas at the lens in response to the sensed ambient air temperature, the sensed lens temperature, and the sensed moisture content.
