FIELD: physics.
SUBSTANCE: system for counting of seeds includes area of image generation, device for reading of image and lens arranged between area of image formation and device of image reading. Extender of optical track arranged between area of image generation and lens develops efficient optical distance between area of image generation and lens, which substantially exceeds physical distance between area of image generation and lens, thus providing for sufficient depth of focus.
EFFECT: increased accuracy of seeds number and rate in process of their sowing, development of compact and portable device to count and measure rate of seeds in a flow.
