Abstract
The device for predicting crack generation in dry noodles is equipped with: a light source that irradiates polarized light on the dry noodles; an image pickup unit that acquires a phase difference image of the dry noodles based on the light passing through the dry noodles as a result of the polarized light irradiated from the light source; and a predicting unit that measures the birefringence phase difference of the dry noodles based on the phase difference image acquired by the image pickup unit and evaluates the residual stress in the dry noodles from the measured birefringence phase difference to predict whether or not cracks will occur in the dry noodles.

-4. (canceled)
A crack generation predictor for dried noodles comprising:
- a light source unit which emits polarized light toward a dried noodle;
- an imaging unit which acquires an image of phrase difference of the dried noodle based on transmitted light through the dried noodle with respect to the polarized light emitted from the light source unit;
- and
- a predicting unit which measures an amount of birefringent phase difference of the dried noodle based on the image of phase difference acquired by the imaging unit and assesses residual stress in the dried noodle based on the measured amount of birefringent phase difference to predict generation of cracks in the dried noodle.
