the capability of taking short exposures (from milli-seconds to
seconds) with negligible dead-time between exposures

![design](forward.gif) |
multi-channels (3 or more) covering a wide wavelength range in
order to (minimally) distinguish a blackbody spectrum from a stellar
spectrum
|
![performance](forward.gif) |
simultaneous measurement of the different wavelength bands to
avoid problems of stochastic variations
|
![performance](forward.gif) |
imaging capability in order to simultaneously measure target,
comparison stars and sky background and to avoid the need for fixed
apertures
|
![performance](forward.gif) |
high efficiency and the capability of being mounted on
large-aperture telescopes
