Scanned laser vein contrast enhancer using one laser

A miniature vein enhancer, for use in imaging subcutaneous blood vessels of a target surface, said miniature vein enhancer comprising:

• one laser, an arrangement of one or more mirrors, and a mirror drive system;
• said one laser configured to emit a beam consisting of light at a selective red wavelength being in the range of 630 nm to 750 nm, said beam of red laser light being received upon said one or more mirrors and thereby reflected onto a target surface to create a spot of light thereon, said spot of light being directed to move rapidly thereon in a pattern using said arrangement of one or more mirrors and said mirror drive system, said mirror drive system configured to drive said arrangement of one or more mirrors to move selectively, said pattern of said selective wavelength of red light forming an image of the blood vessels through differential absorption and reflection;
• and said miniature vein enhancer comprising means for adjusting power to said one laser, to selectively adjust an intensity of said beam of laser light to change the depth of penetration through the skin of the target surface.
