Patent ID: 7918791

Claim:
An optical scanning probe, comprising: a housing; a diaphragm disposed in the housing, wherein the diaphragm and the housing form a chamber; a rotor movably disposed in the chamber, comprising a plurality of fans; a conduit disposed in the housing for conducting a fluid into the chamber, wherein the fluid impels the fans along a first direction to rotate the rotor around a central axis; an optical fiber module, disposed in the housing and through the diaphragm for transmitting a light beam, wherein the fluid serves as an optical medium of the light beam for optical scanning; and a reflector disposed on the rotor and rotated with the rotor to reflect the light beam from the optical fiber module, wherein the rotor and the reflector are disposed opposite to and spaced apart from the optical fiber module along the central axis; wherein the wherein the housing comprises a hole for discharging the fluid from the chamber; and wherein the optical scanning probe further comprises a bag communicated with the hole for receiving the fluid from the chamber; and wherein when the fluid is pumped from the bag into the chamber, the fluid impels the fans along a second direction opposite to the first direction, so that the rotor and the reflector rotate around the axis.
