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 …
