    • The apparatus (100) is for measuring at least one of color and trash in a fiber sample (102). A light emitting diode light source (104a, 104b) generates an incident light (108) that is directed toward the fiber sample (102), and reflected by the fiber sample (102), thereby producing a reflected light (110). A sensor (112a) receives the reflected light (110) and produces a signal. A controller (118) controls the light source (104a,104b) and the sensor (112a), and at least one of receives and adjusts the signal. At least one of the incident light (108), the reflected light (110) and the signal is conditioned to compensate for differences between the light emitting diode light source ( 104a, 104b) and a xenon light source. Thus, drawbacks of the xenon light source used to date can be avoided.
    • 设备(100)用于测量纤维样品(102)中的颜色和垃圾中的至少一种。 发光二极管光源(104a,104b)产生朝向光纤样品(102)的入射光(108),由光纤样品(102)反射,从而产生反射光(110)。 传感器(112a)接收反射光(110)并产生信号。 控制器(118)控制光源(104a,104b)和传感器(112a),并且至少一个接收和调整信号。 调节入射光(108),反射光(110)和信号中的至少一个以补偿发光二极管光源(104a,104b)和氙光源之间的差异。 因此,可以避免迄今使用的氙光源的缺陷。
