Apparatus for analyzing a media, and associated egg identification apparatus and method

An apparatus for non-invasively identifying a present condition of an egg, the apparatus comprising:

• an emitter assembly configured to emit light toward an egg, the emitter assembly having a first emitter source configured to emit a first light signal and a second emitter source configured to emit a second light signal, the first and second light signals being emitted simultaneously and combined into a combined light signal and being transmitted through the egg in phase quadrature;
• a detector assembly configured to detect the combined light signal transmitted through the egg, and further being configured to increase optical power, the detector assembly having a transimpedance amplifier configured to amplify the combined light signal and improve signal-to-noise ratio to the combined light signal in order to simultaneously filter and resolve a relative amplitude or an absolute amplitude of each of the first and second light signals in the detector assembly;
• and
• a processor programmed to process the detected first and second light signals to identify a present condition of the egg using at least one of the relative amplitudes or absolute amplitudes of the first and second light signals.
