Trichromatic Color Sorter

A trichromatic color sorter is a machine or device that is designed to sort objects based on their color using trichromatic (three-color) vision. Trichromatic color vision refers to the ability of humans and many other animals to perceive colors using three different types of color receptors in their eyes.

In the context of a color sorter, trichromatic vision is replicated using various techniques, including the use of three different light sources that emit light in specific wavelengths corresponding to the primary colors: red, green, and blue. These light sources illuminate the objects being sorted, and sensors or cameras capture the reflected light or transmitted light from the objects.

The sensors or cameras detect the intensity of each primary color in the reflected/transmitted light, allowing the color sorter to analyze the color composition of the objects. Based on this information, the sorter can classify and separate objects based on their color properties.

Trichromatic color sorters find applications in various industries, including food processing, recycling, and manufacturing, where it is necessary to sort objects or materials based on their color characteristics. For example, in the food industry, a trichromatic color sorter can be used to remove defective or discolored food items from a production line, ensuring the quality and consistency of the final product.

Overall, trichromatic color sorters leverage the principles of human color vision and use advanced technology to accurately and efficiently sort objects based on their color properties.
