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.

我们正在不断改进我们当前的体内 EEM 系统 可以收集 10 个由 10 种不同光激发的荧光光谱 同一组织的光源和漫反射光谱在更短的时间内 比一秒钟。 这些改进主要在三个方面进行： (a) 使用步进电机获取单独的激发波长 需要时还可以积累多脉冲荧光数据，(b) 使用 紧凑型高灵敏度 CCD 探测器的设计尤其重要 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，使其便携且容易 使用。
