Abstract
An attachment device comprising a cover, with first and second windows, is affixed to a backing, with third and fourth windows, thereby forming a casing. The first and third windows form a first optical path with light entering the third window passing through the first window. The second and fourth windows form a second optical path with light entering the second window passing through the fourth window. A filter housing with a plurality of filters is driven by a motor so that the filters intercept the first optical path in accordance with an imaging regimen electronically stored in the casing interior. The imaging regimen communicates instructions, via a communications interface of the attachment device, to an imager and light source of an external device, to which the attachment device is attached, thereby controlling these components in accordance with the regimen.
