Abstract
An egg identification system for determining viability of an avian egg is provided. Such a system includes an emitter assembly configured to emit electromagnetic radiation toward an egg. A detector assembly is axially aligned with the emitter assembly to detect electromagnetic radiation transmitted through the egg. The detector assembly is spaced-apart from the egg during operation thereof such that the detector assembly does not contact the egg. The detected electromagnetic radiation is used to generate an output signal. The output signal is processed to determine whether there exists a periodic variation or an aperiodic perturbation in an intensity of the electromagnetic radiation transmitted through the egg corresponding to action of a heart or embryo movement, wherein the existence of the periodic variation or aperiodic perturbation indicates that the egg is viable. An associated method is also provided.
