光学衍射和图像重建可用于将生物膜的EM图像与其电子密度投影相关联。这种相关性表明，[盐生盐杆菌的]单个紫色膜颗粒含有9-12个蛋白质分子，63-84个跨膜α，螺旋，复杂性2-10倍以上，以前建议的膜颗粒。
Optical diffraction and image reconstruction can be used to correlate the EM image of the biological membrane with its electron density projection. Such correlation shows that a single purple membrane particle [of Halobacterium halobium] contains 9-12 protein molecules, 63-84 transmembrane .alpha. helices, a complexity 2-10 times greater than that previously suggested for membrane particles.
