Different opinions are presented on the definition of noise and associated performance parameters for infrared detectors and infrared focal plane array detectors in Chinese National Standards GB/T 13584 and GB/T 17444. Without background radiance and signal irradiance level given
the definition of noise in the Chinese National standard can easily lead to fuzzy conceptions of noise and associated performance parameters. When the signal is very strong
the photon noise predominates
signal to noise ratio is not directly proportional to signal level
and care must be exercised in deriving NEP and
D
*
from signal to noise ratio. When the signal is weak
and the photon noise can be ignored
it is very simple to derive NEP and
D
*
from signal to noise ratio.
