A handbreadth-sized laser beam projecting probe for beauty treatment, comprising: a semiconductor laser device for producing a laser beam; a drive circuit for driving the semiconductor laser device; a heat sink for removing the generated heat from the semiconductor laser device; a CPU for controlling the radiation of the laser beam from the semiconductor laser device; a condenser lens for condensing the laser beam from the semiconductor laser device; an adjuster for adjusting the distance between the skin and the condenser lens; and an on-and-off switch associated with an electric power supply. The handbreadth-sized probe can be carried everywhere, permitting the practice of beauty treatment when desired.
An apparatus for laser depilation according to the present invention uses a semiconductor laser diode, which is controlled in respect of its energy level, thereby permitting an economical, effective and safe cosmetic treatment. The power output of light of the semiconductor laser diode ranges from 5 to 1500 mW, and the peak wavelength ranges from 600 to 1600 nm. The controller of the semiconductor laser diode comprises pulsating power output control means and radiation period control means for setting a desired length of time for radiation. With these control means the energy level of the beam of light from the laser may be so controlled that a strong beam of light may be thrown for a relatively short time, or that a weak beam of light may be thrown for a relatively long time. Thus, hairs of different thickness and colors can be removed.
A probe has internal circuitry capable of operating in a plurality of different modes, for example a variety of filter modes and turn off modes. A switch on the probe sends an input to a controller which is arranged to set the mode in response to operation of the switch. The switch may be a push button which is operated externally of the probe by means of an actuator in the form of a plunger. The probe has a workpiece-contacting stylus mounted on a seat from which it is deflectable. The stylus and the seat may comprise the switch. An indicator, e.g., an LED, indicates the mode in response to an output from the controller. The controller outputs a plurality of indications of different modes in a sequence and a mode is selected by operating the switch once the desired mode is indicated.
A probe 10 has internal circuitry capable of operating in a plurality of different modes, for example a variety of filter modes and turn off modes. A switch on the probe sends an input to a controller which is arranged to preset the mode in response to operation of the switch. The switch may be a push button 32 which is operated externally of the probe 10 by means of an actuator in the form of a plunger 34. The probe has a workpiece-contacting stylus 11 mounted on a seat from which it is deflectable. The stylus and the seat may comprise the switch. An indicator, eg an LED 44, indicates the mode in response to an output from the controller. The controller outputs a plurality of indications of different modes in a sequence and a mode is selected by operating the switch once the desired mode is indicated.
An array of light beams is swept along a main scan direction and dithered in a sub-scan direction to generate a treatment pattern of spots. The array is elongated along the sub-scan direction and the dithering has a travel that is significantly less than the length of the array in the sub-scan direction.
An optical pattern generator includes one or more multi-faceted rotating optical elements that introduce an offset that is rotation insensitive. The component that generates the offset is rotationally symmetric around the rotational axis of the optical element. Thus, as the optical element rotates, the effect of the offset component does not change. In addition, rotating optical elements may be designed to counteract unwanted optical effects of each other.
