【摘要】：采用相關(guān)光子法定標(biāo)單光子探測(cè)器的量子效率對(duì)提高光學(xué)載荷的輻射定標(biāo)準(zhǔn)確度具有重要意義.利用355nm連續(xù)激光泵浦BBO晶體產(chǎn)生Ⅰ類自發(fā)參量下轉(zhuǎn)換,在共線和非共線兩種相位匹配模式下分別測(cè)量了單光子探測(cè)器雪崩光電二極管在736nm波段的量子效率.結(jié)果表明,共線和非共線兩種模式測(cè)量結(jié)果的合成不確定度分別為0.71%和0.39%,相對(duì)偏差均優(yōu)于0.4%,這兩種模式都可以定標(biāo)探測(cè)器量子效率,且具有很好的一致性.最后比較了兩種模式定標(biāo)探測(cè)器量子效率的優(yōu)缺點(diǎn),該研究為以后利用相關(guān)光子法對(duì)遙感器進(jìn)行輻射定標(biāo)提供了晶體相位匹配模式選擇的依據(jù).
[Abstract]:The quantum efficiency of single photon detector using correlation photon method is of great significance to improve the radiometric accuracy of optical loading. The quantum efficiency of single photon detector avalanche photodiode in 736nm band is measured in two phase matching modes: collinear and noncollinear, using 355nm continuous laser pumped BBO crystal to produce class 鈪，
