Abstract

A wireless imaging system comprising a head unit and a light cable is provided. The head unit comprises a head unit case, a head unit electrical connector, an image sensor, a wireless transceiver, a central processing unit, and a user-input component. The light cable comprises a light cable electrical connector, a power cable, and an integrated light source. The integrated light source comprises an emissive radiation source having a first spectrum, an optical element located to direct emissions from the emissive radiation source, a volumetric spectrum converter, and an optical reflector located about the converter. The converter converts emissions directed from the emissive radiation source to emissions having a second spectrum different from the first spectrum. The reflector reflects the converter emissions towards the output filter.
