    Abstract: An apparatus for detecting an invisible, near infrared fluorescing mark disposed on a background comprises: an excitation source for exciting the mark, the source having sufficient power to provide a fluorescent signal from a mark situated on at least reflective portion of the background; signal detecting means for detecting the fluorescent signal from the mark; and power modulating means for varying the power between zero and the maximal power level of the excitation source, which is preferably a laser, in a manner effective to produce a decodable fluorescent signal from a mark disposed on any portion of the background. A process for decoding an invisible mark comprising a near infrared fluorescing material comprises: providing at least one invisible, near infrared fluorescing mark disposed on at least one portion of a background; exciting the mark with a laser having a maximal power level sufficient to provide a fluorescent signal from the mark when it is disposed on at least reflective portion of the background; and detecting the fluorescent signal and concurrently varying the power of the laser between zero and its maximal power, thereby obtaining a decodable fluorescent signal at a laser power level between zero and the maximal of a mark disposed on any portion of the background.

    Abstract translation: 用于检测设置在背景上的不可见的近红外荧光标记的装置包括：用于激发标记的激励源，源具有足够的功率以从位于背景的至少反射部分上的标记提供荧光信号; 信号检测装置，用于检测来自标记的荧光信号; 以及功率调制装置，用于以有效地从设置在背景的任何部分上的标记产生可解码的荧光信号的方式来改变优选为激光的激发源的零和最大功率电平之间的功率。 用于解码包含近红外荧光材料的不可见标记的方法包括：提供设置在背景的至少一部分上的至少一个不可见的近红外荧光标记; 利用具有足够的最大功率水平的激光来激励标记，以便当它被设置在背景的至少反射部分上时从标记提供荧光信号; 并且检测荧光信号并同时改变激光在0和最大功率之间的功率，从而获得在零和设置在背景的任何部分上的标记的最大值之间的激光功率电平的可解码的荧光信号。

    Abstract: An apparatus for detecting an invisible, near infrared fluorescing mark disposed on a background comprises: an excitation source for exciting the mark, the source having sufficient power to provide a fluorescent signal from a mark situated on at least reflective portion of the background; signal detecting means for detecting the fluorescent signal from the mark; and power modulating means for varying the power between zero and the maximal power level of the excitation source, which is preferably a laser, in a manner effective to produce a decodable fluorescent signal from a mark disposed on any portion of the background. A process for decoding an invisible mark comprising a near infrared fluorescing material comprises: providing at least one invisible, near infrared fluorescing mark disposed on at least one portion of a background; exciting the mark with a laser having a maximal power level sufficient to provide a fluorescent signal from the mark when it is disposed on at least reflective portion of the background; and detecting the fluorescent signal and concurrently varying the power of the laser between zero and its maximal power, thereby obtaining a decodable fluorescent signal at a laser power level between zero and the maximal of a mark disposed on any portion of the background.
