The input optical power required to produce a signal-to-noise ratio (SNR) of unity. A lower NEP signifies a more sensitive detector. Specific Detectivity ( D*cap D raised to the * power

Incident light creates electron-hole pairs across a p-n junction, generating a voltage or current. radiometry and the detection of optical radiation boyd pdf

Every object with a temperature above absolute zero emits optical radiation. Boyd’s text provides a detailed derivation of the laws governing this thermal emission, which is crucial for infrared system design and thermography. Key Blackbody Laws The input optical power required to produce a
