I have been doing is probably for
15 years or so and it started with the realization
that the fundamental limit
on detection is in the detector.
That doesn't mean the other parts are not also important, but
the optics are already very good and they can be made
to be essentially perfect. But ultimately the light
has to be absorbed by the detector and
in that particular technology area there are
big gains they can be made by improving the technology. So I decided, years ago
to stop doing what I was doing at that time - I was building instruments -
instead I decided forget about the whole instrument.
Let's just concentrate on the one thing that matters the most which is the
detector.
And so I started testing detectors
and the first big project I did was to
evaluate the performance prototype detectors for the James Webb Space
Telescope - the
successor for the Hubble, in the infrared
