VirtualLab Fusion provides non-sequential modeling of multichannel waveguide imaging systems including wavefront error, energy flux and PSF/MTF evaluation as required for VR, AR and MR
In modern display technology, the imaging channel or, in other words, the lightpath from the image panel to the human eye, must be compact while also introducing a lateral offset between panel and eye. In addition, we typically need multiplexing into many imaging channels to provide the image to the eye at different positions. To this end waveguides with gratings are of increasing interest. VirtualLab Fusion enables non-sequential ray and field tracing modeling and design of such devices, including electromagnetic inclusion of grating effects, automatic detection of all relevant lightpaths through the waveguide, and even the calculation of the PSF/MTF for the multi-channel input for any eye position, including the consideration of the partial coherence of the channels.
