Abstract
The abilities of new algorithm - 2D Fast Fourier
Interpolation (FFI) with magnification factor (zoom) 2
to improve the
spatial resolution when necessary are analyzed in details. FFI procedure is
useful when diaphragm/aperture size is less than half of current simulation
scale. The computation noise due to FFI procedure is less than 10-6.
The additional time for FFI is approximately equal to one Fast Fourier
Transform execution time. For some applications using of FFI procedure
decreases the execution time in 104 times compared with other laser
simulation codes.
