Abstract
An imaging device may include first and second optical channels, where each of the first and second optical channels include a discrete optical imaging pathway. The first and second optical channels may be aimed at different angles relative to each other, and each may be directed towards corresponding partially overlapping zones of an object for imaging. Each of the optical channels may include an illuminating source configured to be turned on or off, where illumination from the illuminating sources follow respective illumination paths to the object. Each of the optical channels may additionally include lenses shared by both the respective optical imaging pathways and the respective illumination paths, and each may include an image sensor. The imaging device may also include a computing device configured to turn on the illuminating source of the first optical channel while capturing an image using the image sensor of the second optical channel.
