【摘要】：光陰極輻射靈敏度是衡量紫外探測器響應(yīng)能力的一項重要指標(biāo),實現(xiàn)其準(zhǔn)確測量至關(guān)重要。本文建立了某型紫外探測器光陰極輻射靈敏度測量方法,搭建了實用的紫外光陰極輻射靈敏度測量裝置,重點分析了利用該裝置進(jìn)行紫外光陰極輻射靈敏度測量時的影響因素,對比了紫外窄帶濾光片、光柵單色儀、輻射照度計和輻射功率計等不同組合方式進(jìn)行光陰極輻射靈敏度測量時的誤差情況,得出光柵單色儀配輻射功率計方式在光陰極輻射靈敏度測量時的誤差最小,擴展不確定為9%,相比其它三種組合19.4%、19%和11.2%的擴展不確定度具有絕對優(yōu)勢。該研究成果用于輔助國產(chǎn)紫外探測器技術(shù)研發(fā),為進(jìn)一步改進(jìn)提升其技術(shù)性能提供了有效且準(zhǔn)確的檢測手段。
[Abstract]:Photocathode radiation sensitivity is an important index to measure the response ability of UV detectors. It is very important to measure the photocathode radiation sensitivity accurately.In this paper, a method for measuring photocathode radiation sensitivity of a certain type of ultraviolet detector is established, and a practical device for measuring ultraviolet photocathode radiation sensitivity is built. The influencing factors of ultraviolet photocathode radiation sensitivity measurement with this device are emphatically analyzed.The errors in measuring photocathode radiation sensitivity by different combinations of ultraviolet narrow band filter, grating Monochromator, irradiance meter and radiation power meter are compared.It is concluded that the method of grating Monochromator radiometer has the smallest error in the measurement of photocathode radiation sensitivity, and the spread uncertainty is 9, which is superior to the other three combinations of 19.440% and 11.2% of the extended uncertainty.The research results are used to assist the development of domestic UV detector technology and provide an effective and accurate detection method for further improving its technical performance.
