Physics of incoherent optical propagation
Abstract
Atmospheric optical effects are discussed as relevant to optical/optronical systems, i.e. atmospheric refraction and transmission. The basic relations for atmospheric absorption and scattering are presented. Effects of atmospheric molecules, aerosols, and hydrometeors are described for the wavelength range 0.3 micrometers to 15 micrometers. The general vision formula is presented together with remarks on atmospheric path radiance and on perception range modeling. The definition of visual range and maximum perception range, e.g. with respect to thermal vision through the atmosphere is included. The project OPAQUE is mentioned as an example for the collection of data on atmospheric optical and infrared affects as relevant to the performance of optical/optronical systems and forecasting of the 'optical weather.'
