Chlorophyll fluorescence can be defined as the red and far-red light emitted by photosynthetic tissue when it is excited by a light source. This is an important phenomenon which permits investigators to obtain important information about the state of health of a photosynthetic sample. This article reviews the current state of the art knowledge regarding the design of new chlorophyll fluorescence sensing systems, providing appropriate information about processes, instrumentation and electronic devices. These types of systems and applications can be created to determine both comfort conditions and current problems within a given subject. The procedure to measure chlorophyll fluorescence is commonly split into two main parts; the first involves chlorophyll excitation, for which there are passive or active methods. The second part of the procedure is to closely measure the chlorophyll fluorescence response with specialized instrumentation systems. Such systems utilize several methods, each with different characteristics regarding to cost, resolution, ease of processing or portability. These methods for the most part include cameras, photodiodes and satellite images.
叶绿素荧光可以被定义为当光合组织被光源激发时发出的红光和远红光。这是一个重要的现象，使研究人员能够获得关于光合样本健康状况的重要信息。本文综述了关于新型叶绿素荧光传感系统设计的最新知识，提供了关于过程、仪器和电子设备的适当信息。可以创建这些类型的系统和应用程序来确定给定主题内的舒适条件和当前问题。测量叶绿素荧光的过程通常分为两个主要部分；第一部分涉及叶绿素的激发，有被动或主动的方法。过程的第二部分是使用专门的仪器系统紧密测量叶绿素荧光的响应。这些系统利用几种方法，每种方法在成本、分辨率、处理的便利性或便携性方面都有不同的特点。这些方法大部分包括相机、光电二极管和卫星图像。
