Whole-spectrum, double-CMOS linear imaging sensor detector and detecting method thereof

Abstract

A full spectrum double CMOS linear imaging sensor checking equipment and testing method relates to optics imaging lens, three layers spectral prism, double high speed linear CMOS imaging sensor. Optics lens images object; right angle spectral prism filtrates infrared spectroscopic; separate out two balanced spectrums according to the prism spectral ratio T/R; photoelectric diversion respectively carries by two CMOS sensors; gives goal brightness signal L and color saturation signal S; completes the distinguish of color changing of goal. It takes place the strong and leak single test to blue spectrum (B) signal in common selecting color machine by color saturation signal S test and it accords to the identify habit to color for the vision to people and enhances the identify ability of the equipment.

Description

(1) Technical field: [0001] The invention relates to an optical imaging detection device and a detection method thereof, in particular to a full spectrum, double CMOS linear imaging sensor detection device and a detection method thereof. (two) background technology: [0002] The finished rice is often mixed with yellowed, mildewed and diseased rice grains, which contain aflatoxin, a carcinogen harmful to human body. For these grains with the same size, shape and density as normal rice grains, only According to the color difference on its surface, photoelectric technology is used to identify and accurately remove it. After years of development, optical color sorting detection devices have been used in many industries. Foreign high-performance color sorting detection devices have adopted high-resolution CCD imaging sensor technology, and domestically developed products still use low-resolution silicon photocells to simulate The structure of the electric eye. There are no hig...

Problems solved by technology

No matter at home or abroad, the color sorting and detection devices used in rice and other grain industries still use a single blue spectrum detection technology (see figure 1 ), only in the imported expensive tobacco leaf color sorter in the tobacco industry, there is a detection device that adopts full-spectrum measurement CCD technology to measure (see figure 2 ); The full-spectrum color sorting detection device imported from abroad also has the disadvantage of being expensive
