Abstract
Following exposure to an external light source, determining: 1) the fertility of an avian egg by measuring the photon intensity (photons per second) of the egg's biophoton and luminescence; and 2) the gender of an avian egg by measuring the photon spectrum of the egg's biophoton emission and luminescence. The external light source is either an incandescent, fluorescent, LED, (pulsed or continuous wave) monochromatic or dichromatic laser light source. The detector of the photon intensity is either a low light sensing photomultiplier tube (PMT), silicon based photon counting sensor, or Geiger-mode avalanche photodiode detector. The detector of the photon spectrum is a spectrometer. Following exposure to the referenced light sources, fertile avian eggs will exhibit a higher intensity of photons than that of unfertilized avian eggs, and avian eggs of the female gender will emit a different spectrum of photons than will avian eggs of the male gender.
