Actuator motion control mechanism for a concave mirror

A concave frame and mirror assembly for varying a radius of curvature of a concave mirror to magnify an image of an object in said concave mirror for optimum clarity, said concave frame and mirror assembly comprising:

• a mirror frame comprising a first portion and a second portion, the second portion coupled to the first portion of said mirror frame;
• an actuator coupled to an end of the first portion of said mirror frame, said actuator configured to vary a circumferential length of the first portion of said mirror frame;
• a concave mirror coupled to the first portion of said mirror frame, the first portion of said mirror frame configured to vary a radius of curvature of said concave mirror to magnify an image of said object in said concave mirror for optimum clarity;
• and
• a first proximity sensor coupled to the first portion of said mirror frame, said first proximity sensor configured to measure an axial displacement of said object from a pole of said concave mirror.

A concave mirror assembly for varying a radius of curvature of a concave mirror, said concave mirror assembly comprising:

• a mirror frame comprising a first portion and a second portion coupled to the first portion, the second portion of said mirror frame coupled to a vertical slide;
• a horizontal slide coupled to said vertical slide;
• a fixed support coupled to said horizontal slide;
• a first actuator coupled to an end of the first portion of said mirror frame, said first actuator configured to vary a circumferential length of the first portion of said mirror frame;
• and
• a concave mirror coupled to the first portion of said mirror frame, the first portion of said mirror frame configured to vary a radius of curvature of said concave mirror to magnify an image of an object in said concave mirror for optimum clarity.
