Modèle CI-110

The CI-110’s digital platform enables you to simultaneously capture wide-angle plant canopy images and estimate Leaf Area Index (LAI) and Photosynthetically Active Radiation (PAR) levels from a single canopy scan. No more taking multiple scans above and below the canopy…leave your tree-climbing equipment at home. One measurement provides a full complement of data, unlike systems which require the user take multiple measurements and attach various masking devices to obtain meaningful data.

Features

Single measurement for data collection 150°-wide viewing angle with live high-resolution fish-eye image Collect data under any lighting conditions. The CI-110 accommodates for changes in ambient light Non-destructive measurement of Leaf Area Index (LAI) and Photosynthetically Active Radiation (PAR) On-site evaluation of solar beam transmission coefficients or gap fractions Calculation of diffuse radiation transmission coefficients (the sky view factor), mean foliage inclination angles, and plant canopy extinction coefficients User-selected number of zenith and azimuthal divisions allows investigation of any canopy sectors desired Sun-path can be easily plotted on the image A fully integrated ceptometer with 24 photodiodes to measure Sunflecks in the range of Photosynthetically Active Radiation

Theory Of Operation

The CI-110 Digital Plant Canopy Imager consists of an auto-leveling image capturing probe and arm with 24 PAR sensors, built-in USB interface for an optional laptop or palmtop computer, and software. To calculate PAR and LAI, the CI-110 captures a 150° fisheye image of the canopy, which can be divided into any number of zenith and azimuthal divisions desired. In this way, you may focus on all or any part of the canopy for study. The software digitizes and manipulates the captured images, then calculates the solar beam transmission coefficients, or the fraction of the sky visible from beneath the plant canopy. A value between 0 and 1 is assigned; with 0 meaning no sky is visible below the plant canopy, and 1 meaning that the entire area is sky or no foliage coverage. A fraction indicates partial foliage cover.
