Titel
Projection system for objective, multifocal perimetry
Abstract
A dome projection system for objective perimetric diagnostics was developed. Due to the recommendations from the medical application field, a specially adapted optical system, based on a colour projector with three microdisplays for image generation, an ultra-wide angle projection lens and a separated light source, was designed and realized. The projection system ensures a wide-angle projection of 160°, spot size and chromatical aberration less than 1/4 of the pixel size, and an illuminance of about 900lx.
