Abstract
An annular shutter mirror which can selectively shut off a part of light beams progressing toward a target in the progressing direction thereof. The annular shutter mirror utilizes a fixed reflection face to reflect an incident light beam at a constant angle in accordance with an incident angle of the incident light beam. Around the periphery of the fixed reflection face, at least one flexible reflection face is formed in a shape of annular band. This at least one flexible reflection face selectively reflects an incident light beam at an angle different from a reflective angle of the fixed reflection area in accordance with an application condition of an electrical field.
