## OpticalGainPattern Constructor (Double, Double, Double, Double) |

Create a new instance based on the given aperture diameter, divergence angle, efficiency, and pointing error.

Syntax

protected OpticalGainPattern( double apertureDiameter, double divergenceAngle, double efficiency, double pointingError )

- apertureDiameter
- Type: SystemDouble

The diameter of the optical circular aperture, in meters. - divergenceAngle
- Type: SystemDouble

The beam divergence angle, in radians. Typically represents the angle at which the gain is 1/e^{2}below the on axis (boresight) value. - efficiency
- Type: SystemDouble

The efficiency of the optical antenna. - pointingError
- Type: SystemDouble

The pointing error angle, in radians, for the optical antenna. The pointing error angle is defined as a constant offset which is added to the off-boresight angle, when computing the gain value. The off-boresight angle is the angle between the boresight vector and the link direction vector.
