Analysis of Imaging Systems: Wavefront Error & Effect of Apertures

Imaging systems can be found in various optical applications and they may appear in different configurations.

Such systems can be easily set up in VirtualLab Fusion and their performance can be analyzed with e.g. the wavefront error detector. Especially, apertures in system are known to have an influence on imaging quality. VirtualLab can handle aperture effects properly and take them into consideration for the PSF/MTF calculation. As an example, such effects are demonstrated with a human eye model.

Advanced PSF & MTF Calculation of Imaging System

LightTrans

An imaging system consisting of a collimation objective and a human eye is modeled, and by changing the illumination conditions, the cases with fully and partially illuminated apertures are investigated.

Wavefront Error Detector

LightTrans

The wavefront error is defined as the difference between the reference wavefront phase, constant or spherical, and the detected wavefront phase of a given optical system. This use case shows how to handle the wavefront error detector in VirtualLab.
