The CODE V Beam Synthesis Propagation (BSP) feature allows you to accurately
analyze optical systems containing complex diffraction characteristics. BSP
approximates the optical field as a collection of individual beamlets. A beamlet
consists of a base ray and a field that is initially localized about the base ray.
The base ray defines the reference location and direction for each beamlet.
Based on the fact that the wave equation is linear, these beamlets are propagated
independently and can be summed anywhere downstream to get the propagated
optical field. This method can propagate beams through anything that can be ray
traced, including:
``
Gradient-index (GRIN) materials
``
Birefringent materials
``
Non-sequential ranges

Pre-Analysis also provides an estimate
of the execution time. This preliminary
analysis runs relatively quickly, and
takes the guesswork out of defining
appropriate inputs for your system. Use
of this feature is optional, but highly
recommended.
For the advanced user, BSP offers a
high level of control of the propagation
process, thresholds, and parameters.
Controls are provided for:

graphical user interface (GUI) or in the
command window.
