Title: Method for measuring softening degree of fruit
Inventor: KANAMORI KOJI
IPC: G01N21/35
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To measure a softening degree of a fruit without applying a mechanical external force to the fruit, by projecting light beams to the fruit and detecting lights reaching a plurality of photodetecting points of different distances from a point where the light beams enter. SOLUTION: When a light beam 20 is projected to an illumination point 11 of a fruit 10, the light beam 20 enters the interior of the fruit 10, scatters complicatedly in the fruit, and is partly detected at photosensors 32, 33 arranged at two photodetecting points 12, 13 of distances r1 , r2 from the illumination point 11. A scattering absorption coefficient of the fruit is obtained on the basis of amounts of light detected at the photosensors 32, 33 and a wavelength of light beams 20. A softening degree is strongly correlated to the scattering absorption coefficient. The softening degree of the fruit 10 is measured in a conventional method, e.g. a method using a hit sensor, and also the scattering absorption coefficient of the fruit 10 is measured, thereby forming a graph beforehand.  At an actual measurement, the measured scattering absorption coefficient can be converted to the softening degree with the use of the graph.
