First Claim
Patent Images
1. A method for detecting clouds, the method comprising:
- receiving data from a sensor which is configured to measure polarization of scattered light in a direction substantially opposite to the direction of incident light; and
identifying, from the received sensor data, a cloud based on the polarization of the scattered light.

Abstract
A novel methodology for detecting cloud particles is disclosed herein. This methodology exploits the optical glory phenomenon. According to one embodiment, a method for detecting clouds includes receiving data from a sensor which is configured to measure polarization of scattered light in a direction substantially opposite to the direction of incident light, and identifying, from the received sensor data, a cloud based on the polarization of the scattered light.
