3 Terms and definitions the spectral responsivity R(lambda) of a photodetector is defined as the output of the photodetector as a function of wavelength lambda dY(lambda) divided by the quotient of the photodetector monochromatic input dXe(lambda)=Xe(lambda)dlambda in the wavelength interval dlambda.

R(lambda)=

dY(lambda)

dXe(lambda)

The ratio of the spectral responsivity R(lambda) of the photodetector at wavelength lambda to the given reference value Sm.

Rr(lambda)=

R(lambda)

Rr(lambda) is the relative spectral responsivity of the detector. Sm can be the average, maximum or arbitrary of R(lambda) Value.

4 Overview

Photodetector is a sensor that uses a material with photoelectric effect to convert an optical radiation signal into an electrical signal.

Device. The photoelectric effect is divided into an internal photoelectric effect and an external photoelectric effect. Photodetectors fabricated by external photoelectric effect have photocells and photomultiplier tubes. Photodetectors fabricated using internal photoelectric effects are photoconductive and photovoltaic. Photoconductive detector Lead sulfide, mercury cadmium telluride, photoresistor, etc. Photovoltaic photodetectors are silicon photodiodes, silicon photocells, selenium optoelectronics Pool and so on. In general, whether it is a photodetector made by internal photoelectric effect or external photoelectric effect, their ringing it should only be in a certain spectral region and have strong spectral selectivity. That is, the spectral response of the photodetector Degrees are different at different wavelengths.

5 Measurement characteristics the relative spectral responsivity of the photodetector operating wavelength range and calibration uncertainty are.

Wavelength (300~400) nm. 2.6% (k=2.5);

Wavelength (400~1100) nm. 1.7% (k=2.5);
