6 Getting good extra-focal images.

It is impossible for us to anticipate all possible situations in which this software might be used. However, in the following sections we will give general guidelines for ensuring reasonable results.

This software gives you the capability to reconstruct wavefronts without requiring specialized measurement instruments. Due to the fact that the image acquisition and specification of key algorithm parameters is under user control, Laplacian Optics Inc. cannot in general guarantee the accuracy of reconstructed wavefronts. However with reasonable care, high accuracy wavefront measurements are generally achievable. It is the purpose of this chapter to explain in broad terms the requirements placed on extra-focal images for use with this program. For most optical systems, obtaining good extra-focal images should present few difficulties.

Laplacian Optics Inc. offers a consultation service, to help you with the design and implementation of wavefront sensing solutions. We can help you design measurement procedures and optical hardware, or provide you with a complete system optimized for your particular needs. Please contact Laplacian Optics Inc. for further details.
