Abstract: 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.

Abstract: Optical pattern generators use rotating reflective axicon segments to produce images that can have different dimensions along the pattern direction compared to the cross pattern direction. Examples include both single axicon pattern generators and dual axicon pattern generators that independently control the image space relative aperture and thereby control the image dimensions in two orthogonal directions.

Abstract: Tissue is treated by irradiating it with a sequence of optical pulses that are directed in sequence to various sites on the tissue. During the irradiation sequence, one or more tissue properties are measured at a site(s) that has already been irradiated. These measurements are used to adjust the parameters of subsequent optical pulses in the sequence.

Abstract: Methods and devices for treatment of tissue which first apply a nonablative form of electromagnetic energy to a region of tissue to create a plurality of treatment zones containing coagulated tissue and subsequently apply an ablative form of electromagnetic energy to the coagulated tissue in the treatment zones in order to ablate the coagulated tissue are disclosed. These methods and devices can be used to shrink and/or tighten tissue for medical and cosmetic purposes.

Abstract: A method of reducing the level of pain experienced by a patient during a pain-inducing dermatological treatment by using non-pharmacologic means is described. The method employs the use of multiple bursts of a gas to stimulate a touch sensation in or near the tissue to be treated using the dermatological treatment in order to reduce and/or relieve pain. The method can be used alone or can be used in combination with other non-pharmacologic and/or pharmacologic methods of relieving pain in order to make a patient more comfortable during or following the dermatological treatment.

Abstract: An optical pattern generator uses a rotating component that includes a number of deflection sectors containing optical elements. Each sector deflects an incident optical beam by a substantially constant angle although this angle may vary from one sector to the next. The constant deflection angle is achieved by symmetry within the deflection sector, specifically gut-ray symmetry. The rotating component may be combined with an imaging group that produces, for example, image points, spots, or lines displaced along a line locus. The image spots can also be displaced to either side of a line, for example by introducing a tilt in the orthogonal direction or by introducing light beams at various angles to the plane of symmetry.

Abstract: An optical pattern uses a single rotating component. The rotating component includes a number of deflection sectors. Each sector deflects an incident optical beam by a substantially constant angular amount although this amount may vary from one sector to the next. The rotating component may be combined with an imaging lens group that produces, for example, image points, spots, or lines displaced along a line locus.

Abstract: The present invention relates to a method and apparatus for using an imaging detector to image an optical pattern created by illumination of a viscous material that is applied to the skin. The viscous material forms a detectable pattern that can be imaged by the imaging detector. In some examples, the viscous material is reflective and allows reflection from an illumination source to create an optical pattern on the imaging detector. In other cases, the variation in thickness of an absorbing or scattering viscous substance can be imaged by the detector. Polarized illumination and detection can be used to enhance the response.

Embodiments of the present invention include tips with a security chip and/or a memory.

Abstract: A method and apparatus for fractional treatment of skin by irradiating the skin with electromagnetic energy is disclosed. Sources of the electromagnetic energy can include radio frequency (RF) generators, lasers, and flashlamps. The apparatus includes at least one sensor configured to detect a positional parameter, a skin characteristic, a skin response, or combinations thereof. The sensor provides feedback to a controller. The controller controls the treatment parameters, including the treatment density. By sensing the positional parameter, skin characteristic and/or skin response to a treatment, the controller automatically adjusts treatment density in real-time in response to the sensed positional parameter, skin characteristic and/or skin response.
