What is it about?
At this conference we presented a brief overview of our progress in building optical devices consisting of small elements, ~1mm across. These first attempt devices cleared a lot of technical hurdles and showed us exactly what the main problems were going to be with future device design.

Why is it important?
Pixellated optics can allow for completely new forms of optics system to be designed, for example an approximation of generalised lenses as described in our other work. One potential keystone application for these is as Low Vision Aids where currently patients require small telescopes attached to the front of normal eye glasses. If we can overcome the technical challenges we discussed here, then we can potentially make a device much smaller and lighter to those currently available and possibly even manufactured for an improved cost per device.
Perspectives
This was the first stage of us showing off the work we had been ding as part of the grant which funds our work. In only a short few months we managed to get an initial device out, characterised and lesson extracted which have informed our progress since.
