DEVELOPMENT OF SECOND GENERATION FLUORESCENCE EEM SYSTEM

我们正在不断改进我们目前的在体EEM系统， 可采集10种不同光激发的10种荧光光谱 来自相同组织的源和漫反射光谱在更少的 比一秒钟还多。这些改善工作现正在三个方面进行： (A)使用步进电机获取个人激励波长 当需要时还积累多脉冲荧光数据，(B)使用 紧凑型高灵敏度ccd探测器在 从固有的癌组织部位收集数据 较弱的发射器，(C)简单的电子设备，使其便携和方便 来使用。

We are continuously improving our current in vivo EEM system which can collect 10 fluorescence spectra excited with 10 different light sources and diffuse reflectance spectra from the same tissue in less than a second. The improvements are being carried out in three areas: (a) use of stepper motor to access invidual excitation wavelengths when needed and also accumulate multi-pulse fluorescence data, (b) use of compact high sensitive CCD detector especially important in collecting data from cancerous tissue sites which are inherently weaker emitters, (c) simply the electronics, make it portable and easy to use.
