已知基因特有振動頻帶的紅外二色性，可以提供分子定向的有價值資料。First and second band - gap filters amplify small signals and shift direct current voltage, which filter interference and noise by frequency. then, comparator restrains noise and interference through 700mv voltage window
兩級帶通濾波放大器對熱釋電紅外傳感器採集人體的微弱小信號進行交流放大和直流電平的轉換，並根據頻率對噪聲和干擾進行過濾。39 % of total conversion efficiency at pump level of 600mw 858nm is obtained experimentaily with our single - resonant, external ring frequency - doubler pumped by tr. sapphite laser at room temperature ( about 21. 50c ). the conversion efficiency is seriously limited by what is called " blura " ( blue light induced infrared absorption ) and thermal effects. yet, up to 137 mw of cw blue light at 429nm at pump level of 565 mw has been achieved and stabilized over a hour when the cavity is locked via pound - drever - hall ( pdh ) technique
泵浦功率為600mw時，由於兩種效應「藍光導致紅外吸收（ bliira ） 」和「熱效應（ thermaleffects ） 」的嚴重影響，室溫下（約21 . 5 ）獲得了39的倍頻轉換效率；採用邊帶鎖頻技術， 565mw的泵浦光獲得137mw的藍光輸出，在沒有外界強烈的干擾下可以鎖定1小時以上而不失鎖。
