1. A scanned beam imaging tip, comprising:
- a single mode optical fiber operative to transmit light to a distal end;
a focusing lens aligned to receive light from the distal end of the single mode optical fiber;
a meniscus lens having a semi-reflective inner surface aligned to receive light from the focusing lens and reflect at least a portion of the received light; and
a MEMS scanner aligned to receive light reflected by the inner surface of the meniscus lens and reflect the light toward a field-of-view and operable to scan the light over a two dimensional field-of-view; and
wherein the meniscus lens is operative to shape the light scanned by the MEMS scanner into a beam having a desired shape.

11. A method for imaging a field-of-view comprising:
-
transmitting light through a single mode optical fiber to a distal end; focusing the light from the distal end of the single mode optical fiber with a focusing lens aligned to receive the light; partially reflecting the light from the focusing lens with a meniscus lens having a semi-reflective inner surface aligned to receive light from the focusing lens; receiving the light reflected by the inner surface of the meniscus lens with a MEMS scanner and reflecting and scanning the light over a two dimensional field-of-view through the meniscus lens; and shaping the scanned light with the meniscus lens into a beam having a desired shape. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
