NETD to noise photoelectrons conversion Roadrunner 7/25/2005
I need to convert an infrared camera NETD figure to noise photoelectrons like a visible light camera would have.

I've come up with this idea for the conversion:
* Change NETD to Joules -- the emissitivity in the following equation would be one because the definition of NETD employs black surfaces?

deltaQ=emiss x stefan's const x Area x delta T^4

* Then, I would convert to photoelectrons that represent the energy of one photon, i.e.,
E=hv=3.97^-19joules.

Is this sensible?

Thanks,
Chip (Roadrunner)
