Imaging system with movable tray of selectable optical elements

A system for directing optical signals to one or more imaging elements, comprising:

• a first optical entrance configured to receive a first optical signal;
• a second optical entrance configured to receive a second optical signal;
• an optical element tray having a central axis and configured to be rotatable about the central axis to each position selected from a plurality of positions to allow for formation of one or more optical paths each directing an optical signal of the first and second optical signals to an imaging element of the one or more imaging elements, the optical element tray including:
• one or more optical window openings each positioned to receive the first optical signal and allow the first optical signal to travel through a selected optical window of the one or more optical windows in a direction substantially parallel to the central axis;
• one or more optical channels each positioned to receive the second optical signal and allow the second optical signal to travel in a direction substantially perpendicular to the central axis;
• an incoming reflector configured and positioned to receive the second optical signal from the second optical entrance and redirect the second optical signal to a selected optical channel of the one or more optical channels;
• and
• an outgoing reflector configured and positioned to receive the second optical signal from the selected optical channel and redirect the second optical signal toward an imaging element of the one or more imaging elements;
• and
• a plurality of first optical elements having optical characteristics different from each other, the first optical elements each placed in an optical window opening of the one or more optical window openings or an optical channel of the one or more optical channels,
• wherein the optical element tray is configured to be rotatable to a position allowing for formation of a first optical path of the one or more optical paths, the first optical path including the first optical entrance and the selected optical window opening,
• wherein the optical element tray is configured to be rotatable to a position allowing for formation of a second optical path of the one or more optical paths, the second optical path including the second optical entrance, the incoming reflector, the selected optical channel, and the outgoing reflector.
