Paper Abstract

Experimental investigations ofilgser scintillation through atmospheric turbulence require measurements of irradiance at points in the space. Theories are usually in terms of the irradiance at points; therefore point-aperture results are easier to interpret. Also, the statistics of irradiance at points give more complete information than does aperture-averaged irradiance. Practical reasons however require use of apertures of non-negligible dimensions. Extremely small apertures imply extremely low signal levels and low signal to-noise ratio giving rise to poor measurements. One is therefore faced with the problem of choosing aperture sizes that represent a reasonable compromise between the two opposite requirements. It is therefore important to know whether or not use of a given aperture size simulates a point measurement.
