"Alphas" just got better (1 Viewer)

I have seen info about this new type of lens some months ago and have no doubt that arrays are the future (in many areas, not only in optics) but I believe that the "traditional alphas" are safe, for many years to come...One of my areas of expertise is "array processing" and indeed using a large array of "elements" (such as "micro-lenses=pillars") one can achieve much more than what you can with a single element (such as a "macro-lens") by careful pattern design (think of the high-resolution beamforming capability of large astro-arrays)---it will be interesting to see what arrays can do in optics, but that will take time!

Welcome back Bill.

Thanks for posting this fascinating article and thanks also to Pesto for commenting.

Here is another example of what arrays can do in optics:

The connection to what Bill posted is via the use of arrays: using multiple elements (in this examples inexpensive lenses) to match or even better the performance of an expensive lens.

Use of arrays in optics

Here is another more recent note about the L16 camera:

Watch the video at the end of the article for a short and simple explanation on how the array of lenses works. But things take time (ttt)---the L16 is not yet ready for shipping.
