This invention relates to a method and apparatus for examining eggs, in particular for determining eggshell characteristics of eggs, the method comprising, Such a manner of detection can be suitably applied to sorting machines for eggs. With this methodology, in a short time, for a very large number of products, such as eggs in the present case, a quality parameter such as the strength and/or stiffness can be determined. With such determinations, in an advantageous manner, high requirements set in many fields of technology and industry can be met.

Method and apparatus for examining eggs

This invention relates to a method and an apparatus for characterizing eggshells of eggs, the eggs being supported, comprising: &#x2014;deforming the eggshell, &#x2014;scanning the eggshell with a laser beam of a Self Mixing Laser Vibrometer (SMLV) with scanning signals, whereby a reflection light signal of reflection light is obtained, &#x2014;processing scanning signal and the reflection signal with the SMLV, whereby a mixed signal with crack information is obtained, &#x2014;during scanning moving the eggs relative to the SMLV, &#x2014;comparing the signals with preset criteria and characteristics of such eggs, whereby comparative data are obtained, and &#x2014;characterizing the eggshells on the basis of the comparative data.
