Tissue refractive-index heterogeneity limits the imaging quality of two-photon fluorescence microscopy in vivo by distorting its excitation wavefront and resulting in an enlarged focal volume and ...

A rigorous model, CASIM (corneal ablation simulator), has been developed to model the ablation profile design, the shot-by-shot ablation process and the corneal remodelling that occurs through healing ...

Chromatic aberration (CA), those colorful glowy outlines on hard edges of your high contrast images, can be a real downer when processing or sharing your photography. Luckily, these days removing or ...

Modern camera lenses are complicated. Really complicated. I know, because I tried to fix the aperture control ring on my Canon 24-105 the other day. To cut a very long and confusing story short, I now ...
