    • The inventive method for optically measuring a sample consists in temporarily repeatedly transmitting an electromagnetic signal (2) to the sample in such a way that a substance contained in the sample is transferred from a first electronic state (1) into a second electronic state (3), wherein at least one part of said substance in the second state (3) emits photons which are used for carrying out the optical measurement of the sample, the signal (2) is transmitted to the same sample area at a certain repetition interval and said repetition interval of the signal (2) is adjusted with a lifetime of the second state (3) of the substance having an order of magnitude of 1 ns on a value of at least 0.1 μs which is optimized with respect to photon yield from the substance.
    • 用于光学测量样品的本发明的方法在于将样品中包含的物质从第一电子状态(1)转移到第二电子状态(3)的方式临时重复地将电磁信号(2)发送到样品 ),其中在第二状态(3)中的所述物质的至少一部分发射用于进行样品的光学测量的光子,所述信号(2)以一定的重复间隔传输到相同的样品区域, 所述信号(2)的所述重复间隔在具有1ns量级的物质的第二状态(3)的寿命的至少0.1μs的值上被调整,所述寿命针对来自 物质。
