等溫黑體的探討：現(xiàn)假定有一不等溫黑體腔，將其溫度不均勻近似劃為3個區(qū)域，為了簡化計算并將各面看作相等，光譜發(fā)射率均看作1（只考慮溫度差異的影響，而不考慮發(fā)射率的影響），每個區(qū)域只看作一個溫度（即等價溫度），后面用算術平均值作為黑體腔的溫度。計算結果得出，對于不等溫黑體，光譜能量迭加后當量溫度，不等于不同面積上的溫度算術加權平均值。波長越短，當量溫度越高，如果算術平均值為298.33℃（溫度差異性為±35℃），在0.665μm波長處，當量溫度為318.62℃；而在5μm當量溫度為300.86℃；隨著波長的增加，當量溫度值趨向算術加權平均值，接近300℃。在平均溫度1098.33℃時（溫度差異性±35℃），0.665μm的當量溫度為1102.94℃，與平均溫度差4.6℃；?5μm處當量溫度為1098.57℃，與平均溫度基本接近。那么溫度究竟以哪個為準？很難有個確定的標準。不等溫黑體內(nèi)表面的溫度差異性越大，當量溫度和算術加權平均溫度之差也越大。在相同的溫度差異性上，隨著黑體自身溫度的升高，當量溫度與平均溫度差值下降。

style="text-indent:25px">黑體概述：盡管自然界不存在完全理想化的黑體，但實際工業(yè)應用中，黑體輻射率已經(jīng)可以達到0.93～0.998，用于檢測的標準源黑體輻射率已經(jīng)可以近似為1。通過將黑體設置在熱成像視野范圍內(nèi)，利用黑體的特性開展測溫標定，進行測量溫度實時校正，將視頻畫面和個人體溫對應顯示，大幅度提高人體測溫的測溫精度，減少測溫誤差到±0.2℃。黑體一般會搭配熱成像攝像機使用，熱成像技術在**期間，能夠減少人員的相互接觸，一般會在人流量大的地方部署體溫篩查通道，助力于**防控。我公司在黑體領域深耕10余載，由于黑體通用設備，可以匹配國內(nèi)外所有熱像儀廠家如：大立科技，高德紅外，大華股份，海康威視，艾瑞科技，等**廠家的熱像儀配套使用，只需要一個三腳架，就可以跟黑體鏈接使用。黑體爐不準時如何校準的。上海測溫儀黑體爐</p><p
