Area measuring apparatus, in particular leaf area measuring apparatus determines the area of an object and has memory means for storing data representing the area of the object so that the data thus stored may be output at a later time to a printer or computer. The apparatus comprises a transparent conveyor which conveys the leaf being measured between a light source and a linear detector array, and means to count signals from the array to determine the leaf area. Detector sensitivity may be adjusted so that only signals above a predetermined level are counted. <IMAGE> |
