Abstract
The present invention is directed to a two-dimensional scanning arrangement for a laser vein-illumination device that includes a base and a frame connected to the base using at least one flexible hinge. The hinge allows the frame to move angularly with respect to the base in a first direction. The invention further includes a means for exciting angular oscillations of the frame at or near said frame'"'"'s resonant frequency. An elastic torsional element having a proximal end rigidly attached to said frame and a distal end rigidly attached to a mirror is also included. The torsional element allows the mirror to move angularly with respect to the frame in a second direction, generally perpendicular to the first direction. There may also be a means for exciting the angular oscillations of the mirror.
The invention also includes a device for optically inspecting confined spaces having one or more small access orifices. The device includes at least one laser light source and a scanning means which scans one or more laser beam in a two-dimensional pattern over an inspection area. Also present is at least one light detector, sensitive to the light of the laser beam(s) being reflected from the inspection area. There is also a connecting member being thin and long enough to reach the inspection area through the access orifice.
