Abstract

Methods and apparatus that can non-invasively identify the present condition of eggs, namely, whether an egg is a live egg, a clear egg, an early dead egg, a middle dead egg, a late dead egg, a rotted egg, a cracked egg, and/or an inverted egg, are provided. An egg is illuminated with both visible and invisible light at wavelengths of between about three hundred nanometers and about eleven hundred nanometers (300 nm-1,100 nm). Light passing through the egg is received at a detector positioned such that a path of the received light does not pass through an aircell within the egg, except in the case of an inverted egg. The intensity of the light is determined at a plurality of the visible and infrared wavelengths, and a spectrum that represents light intensity at selected ones of the visible and infrared wavelengths is generated. The generated spectrum is compared with one or more spectra associated with a respective known egg condition to identify a present condition of the egg.
