That ball would certainly have impacted my eyeball if I'd been wearing
lensless guards.
The advantage is that the additional components needed for conventional OCT can be compensated numerically with a computer, making
lensless imaging by reconstruction of the scattered waves possible.
The imaging platform is called LUCAS (
Lensless Ultra-wide-field Cell monitoring Array platform based on Shadow imaging).
On April 29, take a photo with a
lensless camera and upload the picture to http://pinholeday.org/.

Last year, Hajimiri's team rolled out a one-dimensional version of the camera that was capable of detecting images in a line, such that it acted like a
lensless barcode reader but with no mechanically moving parts.
