1. A system for scanning a target using a multiple reference optical coherence tomography device, said system comprising:
a first housing of a first set of optical sources; a second housing of a second set of optical sources, a scanning module positioned between said first and said second housing so that where radiation from said first set of sources in said first housing is directed to a scanning module from a first linear direction, and radiation from said second set of sources in said second housing is directed to said scanning module from a second linear direction opposite to said first linear direction; and where, said scanning module includes
a first optical beamsplitter with a first beamsplitting surface 107 and a first partially reflective surface 109, said first partially reflective surface reflecting approximately eighty percent of radiation, where incoming probe radiation from said first set of optical sources passes through beamsplitting surface to a reference optic 113 said reference optic having a first highly reflective surface 111, said first highly reflective surface reflecting approximately ninety-five percent of radiation, and where said first partially reflective surface 109 of said first optical beamsplitter 105 is parallel to said first highly reflective surface 111 of said reference optic 113;a second optical beamsplitter 125 with a second beamsplitting surface 127 and a second partially reflective surface 129, said second partially reflective surface reflecting approximately eighty percent of radiation, where incoming probe radiation from said second set of optical sources 123 passes through said second beamsplitting surface 127 to said reference optic 113 having a second highly reflective surface 131, said second highly reflective surface reflecting approximately ninety-five percent of radiation of said reference, and where said second partially reflective surface 129 is parallel to the surface 131 of said reference optic 113;and further where said reference optic 113 is coupled to a first actuator which oscillates said reference optic in a lateral direction, which second actuator moves said scanning module in said lateral direction; and a two dimension detector array 133 which receives optical radiation reflected from said target 117 and reference radiation reflected from the first and second highly reflective surfaces of said reference optic and said first and second partially reflective surfaces 109 and 129, creating interference signals corresponding to depth scans of said target. |
