Device for remote sensing of vehicle emission
First Claim
1. A device for remote sensing of emissions of a vehicle driven on a road, comprising:
- (a) a source for emitting a beam of light and transmitting the emitted light through an exhaust plume emitted from the vehicle to the surface of a lane of the road on which the vehicle is driven, wherein the transmitted light is scattered at the surface of the lane;
(b) a detector for receiving at least one portion of the scattered light scattered from the surface of the lane; and
(c) a processor for processing the received light therein to provide one or more spectra of the received light so as to determine components and concentrations of the exhaust plume,wherein the source and the detector are located in the same side of the road.

Abstract
In one aspect, the present invention relates to a device for remote sensing of emissions of a vehicle driven on a road. In one embodiment, the device includes a source for emitting a beam of light and transmitting the emitted light through an exhaust plume emitted from the vehicle to the surface of a lane of the road on which the vehicle is driven, wherein the transmitted light is scattered at the surface of the lane; a detector for receiving at least one portion of the scattered light scattered from the surface of the lane; and a processor for processing the received light therein to provide one or more spectra of the received light so as to determine components and concentrations of the exhaust plume. The source and the detector are located in the same side of the road.

16. A device for remote sensing of emissions of a vehicle driven on a road, comprising:
-
(a) a source for emitting a beam of light and transmitting the emitted light through an exhaust plume emitted from the vehicle to the surface of a lane of the road on which the vehicle is driven, wherein the transmitted light is scattered at the surface of the lane; (b) a detector for receiving light and processing the received light therein to provide one or more spectra of the received light, wherein the detector and the source are located in the same side of the road and define an optical path therebetween; and (c) a collecting optics positioned in the optical path for collecting the scattered light scattered from the surface of the lane and delivering the collected light to the detector. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
