Coherent imaging fiber based hair removal device
View Patent ↗A photoepilation device including a compact hand piece applicator and a portable electronics module for use in a non-medical setting. The hand piece, which contains no electrical signals, allows the user to focus on individual hair follicles by observing a magnified image provided on a semiconductor display. The image from the hand piece is transported to a remote CCD through a coherent imaging fiber. which also delivers the therapeutic energy pulse from a remotely located source to the localized target. Destruction of pluripotential follicular stems cells found in the hair bulb and bulge regions is possible via a single low power laser diode. Control of pulse width and spot size attains a range of fluence levels up to 85 J·cm −2 .
1. A portable device comprising:
a coherent imaging fiber;
an optical switch;
a plurality of multimode optical fibers; and
an imaging microlens assembly,
wherein the coherent imaging fiber transports an image of a targeted hair follicle for viewing by a user of the portable device, and
wherein the coherent imaging fiber delivers laser energy to the targeted hair follicle.
2. The portable device of claim 1 , wherein cellular structures of the targeted hair follicle are damaged by elevated temperature photo-induced by the laser energy.
3. The portable device of claim 1 , wherein the coherent imaging fiber includes an outer ring comprising the plurality of multimode optical fibers for illumination of the targeted hair follicle.
4. The portable device of claim 1 , wherein the optical switch modulates an optical signal to define ON/OFF states of the portable device.
5. The portable device of claim 1 , further comprising a radially bi-focal lens providing disparate magnifications for the coherent imaging fiber and the plurality of multimode optical fibers.
