7. CALCULATING NOISE FIGURES FROM PHOTONS FROM WATTS
----------------------------------------------------
This paragraph is not contained in this free edition!


Key words:
MEAN | PIXEL PHOTOSITE | EXPOSURE TIME | IRRADIANCE | JOULE | SATURATION PIXEL ENERGY | PHOTON'S ENERGY | NUMBER OF PHOTONS | DYNAMIC RANGE | FULL WELL CAPACITY

Description:
Why do we need photons? - How do we get the number of photons? - Finally the noise figure - Discussion and full well capacity.
One spreadsheet for Microsoft Excel (25 kByte) with 3 examples "ENOB from full well data". 3 CCD data sheets.

Size:
9 kByte of html.
