Abstract
In one embodiment, a particle sensor on or in a vehicle is provided. The laser particle sensor comprises an optical system; a processing system coupled to the optical system; wherein the optical system is configured to transmit one or more laser light beams to detect particles in a volume of freestream fluid, and to have the one or more light beams terminate on a portion of the vehicle on which the optical system is mounted; and wherein the optical system is configured to receive a backscattered portion of the one or more laser light beams transmitted by the optical system.

A laser particle sensor on a vehicle, comprising:
- an optical system;
- a processing system coupled to the optical system;
- wherein the optical system is configured to transmit one or more laser light beams to detect particles in a volume of freestream fluid, and to have the one or more light beams terminate on a portion of the vehicle on which the optical system is mounted;
- and
- wherein the optical system is configured to receive a backscattered portion of the one or more laser light beams transmitted by the optical system.
A system, comprising:
- a vehicle;
- and
- a laser particle sensor mounted to a first portion of the vehicle, wherein the laser particle sensor includes a laser transceiver and collection optics, wherein the laser transceiver is configured to transmit one or more laser light beams, wherein a window of the laser transceiver is fixed and oriented to transmit the one or more laser light beams toward a second portion of the vehicle, wherein the laser particle sensor is configured to detect particles in a volume of freestream fluid in a selected measurement region, wherein the selected measurement region is positioned between the window of the laser transceiver and the second portion of the vehicle, wherein the laser particle sensor is configured to receive a backscattered portion of the one or more laser light beams transmitted by the laser particle sensor.
A system, comprising:
- a vehicle;
- an optical system mounted to a first portion of the vehicle;
- and
- a processing system coupled to the optical system;
- wherein the optical system is configured to:
- transmit one or more laser light beams to detect particles in a volume of undisturbed airflow in a selected measurement region between the first portion of the vehicle and a second portion of the vehicle, wherein the one or more laser light beam terminate on the second portion of the vehicle;
- and
- receive a backscattered portion of the one or more laser light beams transmitted by the optical system.
