Deep-color fiber decoloring microscopic system and method

Abstract

The invention relates to a deep-color fiber decoloring microscopic system, and relates to the technical field of fiber detection. The deep-color fiber decolorization microscopic system comprises a light source, an objective table, an optical amplification unit, a CMOS photoelectric sensor and a processing terminal; the objective table is used for arranging an oil-immersed fiber sample slide, and a visible light / infrared light switching insertion sheet is arranged between light paths between the objective table and the optical amplification unit; the switching insertion sheet comprises an insertion plate body, a first optical filter and a second optical filter; the first optical filter is a visible light transmission infrared light cut-off optical filter, and the second optical filter is infrared light transmission visible light absorption glass; and the CMOS photoelectric sensor converts an optical signal into an electric signal, and the processing terminal processes the electric signal to obtain a fiber digital micrograph. The invention also relates to a deep-color fiber decoloration microscopic method, wherein the method uses a non-chemical method based on a CMOS device, losslessly achieves the decoloration imaging effect on a deep-color fiber, and can clearly reflect the texture characteristics of the deep-color fiber.

Description

technical field [0001] The invention relates to the technical field of fiber detection, more specifically, the invention relates to a dark fiber decolorization microscope system and method. Background technique [0002] my country is a big textile country, and both the wool spinning industry and the cotton spinning industry are in the forefront of the world. Textile testing is an important part of quality control in the entire industrial chain, and microscopic inspection of natural textile fibers is one of the main testing items. Regardless of fluffy textiles or cotton and linen textiles, fiber microscopy mainly relies on microscopic imaging equipment such as fiber fineness meters, which are detected based on the texture and structure characteristics of the fiber surface. With the rapid development of the textile industry and the printing and dyeing industry in recent years, dark fabrics have increasingly appeared in people's lives. However, due to the poor light transmiss...

Problems solved by technology

Moreover, because it uses high-cost CCD photosensitive devices, it cannot compete with cost-effective CMOS devices, so the current mainstream digital photosensitive imaging equipment (all kinds of digital cameras, cameras) are based on the latter

In addition, for samples where dark dyed and undyed fibers coexist, due to the huge difference in visible light transmittance between the dye and the fiber itself, there will be a huge difference in the optical signal intensity of the two fibers, so that the dynamic range of the imaging device is exceeded, forming ( Overexposure (for light-colored fibers) or underexposure (for dark-colored fibers) also cannot be imaged normally
