Measurement Of The Uv Radiation Flux

Nowadays, with the ultraviolet radiation's biologic effect cared by more and more people, its appraisement becomes a very important business. As a so basilic qualification that the radiant flux attracts more and more people's attention.In this thesis, being based on this purpose, we designed two different systems, which can be used to measure the UV radiant flux. We respectively name them as the integrating spheres measurement system a-nd the Gonioradiometry measurement system.Firstly, in the integrating spheres measurement way, if we want to get exact result the radiant flux standard lamp is needed. At last I find a new abutting joint method to extend the system response ratio to ultraviolet band. Of course, for other influence factors for example the coating, absorptance and so on , I get the corresponding method.Because of the the integrating spheres measurement system can not settle the problem that the spectrum distribute uneven in the space. So we design another system- the Gonioradiometry measurement system. It can settle this problem commendably. Thereinto, the space rotating stage's design is the key point and we choose the way of light source rotating.At the end of this thesis, I compare themselves each other while this two systems' characteristics are analysed and reach the conclusion of the Gonioradiometry measurement system exceeding the integrating spheres measurement system.This thesis not only introduce the principle of the UV radiation's measurement but also present the experiment data. In the process of d-esigning the two systems, I find a new method which can ameliorate the cosine effect of the detector.
