Fiber blend identification and/or ratio measurement

The present invention relates to a measurement instrument (100) and a corresponding method for identifying a fiber blend composition and/or fiber blend ratio in an input material (108). The input material can be moved by a first fiber movement set at a first speed towards a second fiber movement set which provides the input material at a second speed to a sample sensing module (104), through whichthe input material is then moved by a third fiber movement set (126a, 126b). Electromagnetic radiation sources (114,120) direct radiation toward the input material (108) at first and second locations, and electromagnetic radiation sensors (116,122,124) are configured to receive the transmitted or reflected radiation. A controller (128) processes the signals from the sensors to determine the fiberblend composition and/or the fiber blend ratio in the input material (108). The controller (128) also sends control signals to the radiation sources and the fiber movement sets. 一种用于识别由第三纤维运动组件(126a，126b)移动的输入材料(108)中的纤维混纺物组成
