Portable cost-effective fiber analyzer

The invention provides a portable cost-effective fiber analyzer which detects the length and width of plant fiber. The portable cost-effective fiber analyzer includes a sample introduction flowing module, an observation module, a shooting module, and an image analyzing module. The sample introduction flowing module automatically introduces samples through liquid level control and a timer; the observation module uses a special square glass tank, so that the fiber imaging defocusing problem is reduced, and fiber plugging can be effectively prevented; the shooting module includes a camera, a microscope lens, an LED light source, and a lens; and the image analyzing module includes a microcomputer and a fiber analyzing program. The portable cost-effective fiber analyzer has the advantages of high cost performance, high precision, and portability.
