摘要

PURPOSE: An apparatus for measuring chlorophyll in crops is provided to measure an amount of chlorophyll contained in crops in real time by utilizing a GPS. CONSTITUTION: A chlorophyll measurement apparatus includes a leans section(100) for collecting solar light reflected from leaves of crops, a filter section(110), an optical sensor section(120), a signal processing section(130), a data processing section(140) and a supporting section. The lens section(100) has a lens(102) and a lens holder(104) for fixing the lens(102). A focus adjusting part(106) is provided in the lens holder(104) in order to adjust the focus of the lens(102). The filter section(110) includes a visible ray filter(114), a near-infrared ray filter(116) and a filter holder(112) for fixing the visible ray filter(114) and the near-infrared ray filter(116). The optical sensor section(120) has a visible ray sensor(122) and a near-infrared ray sensor(124).
