  • Visibility determination in environments containing airborne dust particles
    Patent number: 8478529
    Abstract: Determining optical visibility in an environment that may contain airborne dust particles is described. In one aspect, a method determines an ambient relative humidity in the environment. A near infrared wave is transmitted through a portion of the environment. An optical visibility in the environment is calculated based on the ambient relative humidity and attenuation of the near infrared wave during transmission through the environment. Various contrast thresholds are employed in the determination of optical visibility in the environment.
    Type: Grant
    Filed: June 28, 2010
    Date of Patent: July 2, 2013
    Assignee: King Saud University
    Inventors: Abdulaziz Salem Al-Ruwais, Abobakr Sultan Ahmed
