OpenHSI ~ How it all began…

Firstly, if you don’t know what OpenHSI is, then I suggest you go and read it’s very excellent github site/pages: https://openhsi.github.io/


The ‘story’ is I was a chief investigator in the ARC Training Centre Cubesats, UAV’s and their applications, see: https://www.cuava.com.au/

I had a number of PhD students at the School of Physics at The University of Sydney at the time including Dr Yiwei Mao and Samuel Garske.

Professor Sergio Leon-Saval and Dr Chris Betters from SAIL were collaborating on hyperspectral imaging spectrometers, for cubesats.

Then COVID hit!

My students, collaborators and I were all stuck at home and we we got talking (on Zoom) about the work of Fred Signernes and his hyperspectral imager.

So we hatched a plan to iterate on Fred’s design, and Sergio and Chris got on the case and produced a design,… we all tinkered away on our parts (especially Chris and Yiwei) from home (often on the kitchen table) and then when COVID broke, we had a hyperspectral imager, OpenHSI 1, as pictured above (note: the SAIL logo is on the side not in view!).

Yiwei and Sam got to work applying it, testing it and developing software and anxcillaries for it, and published their work !… and OpenHSI was born.

Dr Yiwei Mao has so far published a number of papers on OpenHSI as part of his (now passed!) PhD Thesis:
