“…The reference trap was a reflection trap constructed using Hamamatsu S1227-1010BN photodiodes. This type of photodiode is known to behave linearly [8]. Several S1227 photodiodes were checked using a nonlinearity measurement facility which uses the double-aperture method described in [9].…”

Trap detectors are useful transfer standards well-suited to modern absolute radiometry. A potential problem with them is that cryogenic radiometers allow only small-diameter laser beams to enter the absorber cavity. This can significantly increase nonlinearity effects of the trap detectors even at radiant power levels below 1 mW. The results of nonlinearity investigations at 633 nm of Si reflection trap detectors are presented. Four types of trap were studied: the commercially available QED100 and QED200, and constructed traps using Hamamatsu S1227-1010BN and S1337-1010BN photodiodes. The quantum efficiency was investigated as a function of radiant power as well as of the bias voltage and beam diameter.

Radiometry based on black bodies remains one of the fundamental fields of radiometry. Black bodies are widely used as standard sources in radiometry of noncoherent optical radiation from the ultraviolet to the far-infrared spectral regions. Outstanding progress in radiometry has been made in the last decade due to development of high-precision cryogenic radiometers, which have made it possible to decrease the measurement uncertainty to 0,01 %. New technology and optical physics call for significant improvement in the accuracy of black-body-based radiometry and the practical realization of spectral radiance and irradiance scales having an accuracy of 0,1 %. However, the accuracy of black-body-based radiometry is now limited by the accuracy of thermodynamic temperature measurements of a radiating cavity. For example, the uncertainty of spectral radiance and spectral irradiance scales is from 0,5 % to 1 % in the UV due to uncertainties in pyrometric measurements. The required uncertainty of modern black-body-based radiometry is about 0,1 %. This can be achieved by using the latest advances in the field of high-precision radiometric instrumentation, such as absolute radiometers, large-area high-temperature black bodies and synchrotrons.

Differential spectroradiometry is based on the determination and analysis of the differential spectral response of photoelectric devices in the presence of bias irradiance that can be varied with wavelength and over many orders of magnitude. The principle is described. Differential spectroradiometry is particularly suitable for the following applications that are reviewed or illustrated by some examples: determination of spectral and weighted responsivities allowing the transfer of the spectral responsivity scale to high levels of irradiance; determination of nonlinearities in the photocurrent-irradiance characteristic; non-destructive characterization of photoinduced effects.
