Lensless Optics Debate
Discussions center on whether 'lensless' imaging systems actually use lenses or simulations, comparisons to Fresnel lenses, optical aberrations, and improvements in lens design.

"Lensless" but actually has multiple lenses?
Probably shaping the lens/mirror correctly?
It does simulate the lens, it says so in the article
Lenses are needed to capture light.
Could this be considered a higher “resolution” fresnel lens?
Why could the optics be improved?
seriously if something was done to manipulate the optical lenses to optimise for usage mode it would be helpful
It looks like a Fresnel lens taken to the limit.
More than likely some sort of lens (IR/visual) optical effect.
Couldn't you just use a laser and a lens?
