COHERENT

Sets the beam summing mode to coherent. The syntax is:

COHERENT

The coherent sum of any two beams is computed by summing the point-by-point real and imaginary parts of the two beams. The phase of the resulting beam thus depends upon the vector sum of the components. All subsequent beam sums will be coherent unless an INCOHERENT command is used.

See also INCOHERENT . The default sum mode is COHERENT.
