Nice ghost imaging implementation on a chip. Even though the optical part has been quite well-known for a while, I really like the fact that more groups are starting to incorporate FPGA cards in their optical systems (if only they were easier to use!). Seems like a very interesting way of speeding-up the post-processing of the signal in order to

Using a ground glass diffuser before a pixelated detector, and after a calibrating procedure where you measure the associated speckle patterns when scanning the sample plane, a single shot of the fluorescence signal speckle pattern can be used to retrieve high spatial resolution images of a sample.

Probably I will write longer posts about some of them in the future. Let’s get this thing going: Two papers using ‘centroid estimation‘ to retrieve interesting information: Extract voice information using high-speed camera Mariko Akutsu, Yasuhiro
