schreiber教授因發明pam系列調制葉綠素熒光儀而獲得首屆光合作用協會（ispr）創新獎

利用調制葉綠素熒光技術，測量野外自然水體或培養的微藻樣品的光合作用（葉綠素熒光誘導加淬滅分析、光響應曲線等），也可測量葉綠素含量，是進行野外光合作用研究的良好工具。除了測浮游植物外，可擴展探頭測量附著藻類或大型藻類。除了取水樣到樣品杯中測量外，可擴展探頭進行水下原位、連續測量，特別適合于連續監測海洋、湖泊、水庫、河流等水體的葉綠素含量以及光合活性。

功能：
1）可單機操作，可連接電腦操作
2）可測葉綠素熒光誘導曲線并進行淬滅分析
3）可測光響應曲線和快速光曲線（rlc）
4）可測量水樣的量子產量（光合效率）和相對電子傳遞速率（光合速率）
5）51個內置模式菜單，方便參數設置和標準測量
6）靈敏度高，檢測限為0.1 μg l^-1 chl
7）三種配置：
系統i用于浮游植物研究；系統ii用于附著藻類和大型藻類研究；系統iii用于連續監測水體光合作用
8）主機為通用控制單元pam-control，可擴展為microscopy-pam和microfiber-pam
