    • For the high spatial resolution imaging of a structure of interest in a specimen, a substance is selected from a group of substances which have a fluorescent first state and a nonfluorescent second state; which can be converted fractionally from their first state into their second state by light which excites them into fluorescence, and which return from their second state into their first state; the specimen's structure of interest is imaged onto a sensor array, a spatial resolution limit of the imaging being greater (i.e. worse) than an average spacing between closest neighboring molecules of the substance in the specimen; the specimen is exposed to light in a region which has dimensions larger than the spatial resolution limit, fractions of the substance alternately being excited by the light to emit fluorescent light and converted into their second state, and at least 10% of the molecules of the substance that are respectively in the first state lying at a distance from their closest neighboring molecules in the first state which is greater than the spatial resolution limit; and the fluorescent light, which is spontaneously emitted by the substance from the region, is registered in a plurality of images recorded by the sensor array during continued exposure of the specimen to the light.
    • 对于样本中感兴趣的结构的高空间分辨率成像,物质选自具有荧光第一状态和非荧光第二状态的物质组; 其可以通过将它们激发成荧光的光从其第一状态分数转换成第二状态,并且从它们的第二状态返回到其第一状态; 将感兴趣的标本的结构成像到传感器阵列上,成像的空间分辨率极限比样品中物质的最接近的相邻分子之间的平均间距更大(即更差) 试样在具有大于空间分辨率极限的尺寸的区域中暴露于光,该物质的部分交替地被光激发以发射荧光并转换成其第二状态,并且至少10%的 分别处于第一状态的物质,其处于与第一状态相比最大相邻分子一定距离,该距离大于空间分辨率极限; 并且由该区域内的物质自发地发出的荧光被记录在传感器阵列记录的多个图像中,该样本在样品持续暴露于光下。
