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

An apparatus for interrogating a media to be analyzed, such as an avian egg (1), is provided. Such an apparatus (160) includes an emitter assembly (200) configured to emit light toward a media. The emitter assembly has a first emitter source (210) configured to emit a first light signal and a second emitter source (220) configured to emit a second light signal. The first and second light signals are transmitted through the media in phase quadrature. A detector assembly is configured to detect the first and second light signals transmitted through the media. The detector assembly (300) is further configured to resolve a relative or absolute amplitude of each of the first and second light signals. A processor (600) is configured to process the detected signal to identify a property of the media using at least one of the relative and absolute amplitudes of the first and second light signals. An associated method is also provided. Figure 5 z 11/1 coc ClC 0 --a ~a z PROJF ION F
