摘要： A computer-implemented method (100) is described. The method comprises receiving (102) first and second imaging data obtained by an imaging system (204) of a subject (202) illuminated by first illumination (206a) in a first spectral band and second illumination (206b) in a second spectral band comprising different spectral content to the first spectral band. The second illumination incident on the subject is polarized. The received first imaging data is obtained within the first spectral band. The received second imaging data is obtained within the second spectral band. The the first and second illumination are admitted, via an imaging system polarizer (310) of the imaging system, into the imaging system depending on a polarization state of reflected first and second illumination received by the imaging system after reflection from a surface of the subject. Information regarding specular reflection from the surface of the subject is determined by comparing the first and second imaging data.

摘要： In a hair styling device (100) comprising electrodes (102) for applying a radio- frequent signal to hair, a frequency of the radio-frequent signal is between 50 MHz and 90 MHz. Preferably, a voltage of the radio-frequent signal does not exceed 30 V, while a voltage not exceeding 10 V would work well in a configuration that applies another heat source (103) for heating hair up till a first temperature that is no more than 150 °C (and thus lower than a critical temperature at which hair cuticle damage will occur), and the radio-frequent electrodes (102) for – in combination with heat from the other heat source (103) - selectively heating a hair cortex to a second temperature exceeding the first temperature and sufficiently high for hair styling.

摘要： The invention relates to a skin treatment device (10) for fractional treatment of the skin (100) of a human being. A radiation source (5) emits a multi-mode laser beam (20) with a superposition (23) of mutually different higher-order laser modes. The multi-mode laser beam is configured by said superposition of different laser modes to simultaneously cause a first plurality of high-intensity zones, where the thermal threshold (TC) for collagen denaturation for the treatment zone (50) of the skin is at least reached, and a second plurality of low-intensity zones where the thermal threshold (TF) for fibroblast stimulation for the treatment zone of the skin is at least reached. This is advantageous for obtaining a skin treatment device with a simple and therefore low-cost fractional laser skin treatment system for combined collagen denaturation and fibroblast stimulation. The skin treatment device is based on non-uniform laser radiation in the form of the multi-mode laser beam.

摘要： The invention relates to a device (100) for RF skin treatment comprising an outer electrode (2) arranged on an operational side (15) of the device. The outer electrode has an annular or equilateral polygonal shape. An inner electrode (1) is arranged at a center of the outer electrode and is surrounded by the outer electrode. An RF generator (21) is arranged to supply an RF treatment voltage between the inner electrode (1) and the outer electrode (2). A skin contact surface of the inner electrode has a largest cross-sectional dimension in a range of200 –500 μm, and the RF treatment voltage is less than 50 V. The invention provides a device with improved safety in that it enables the creation of non-ablative fractionated skin lesions,particularly using a relatively low RF treatment voltage for treating the skin as compared to known devices and without the necessity of a feedback or monitoring system.

摘要： The invention relates generally to the treatment of skin using laser light, and more particularly to a non-invasive device and method for such treatment. During skin treatments, heating of the epidermis is undesired because it may cause discomfort for the person being treated, adverse skin reactions and unwanted changes in skin pigment. The invention provides a laser treatment beam having a first 22a and a second 22b beam region of non-zero light intensity disposed at a periphery of a transverse cross-section of the beam, and a third beam region 22c, arranged between the first 22a and the second 22b beam region, of lower light intensity than said non-zero light intensity. The treatment beam 22 exits the device 10 along its optical treatment axis 13. As the treatment beam 22 passes through an outer layer of the skin to the focal spot 25 along the optical treatment axis (13), the extent of the third beam region 22c is predetermined and/or controlled so as to provide a corresponding third skin region 23c in the outer skin layer16, arranged between the first 23a and the second skin region 23b, and the lower light intensity of the third beam region is predetermined and/or controlled to provide a maximum temperature during a pulse of the laser treatment beam with in the third skin region 23c which is lower than the maximum temperatures during said pulse of the laser treatment beam within the first 23a and the second 23b skin region. The light source 20 is configured and arranged to provide, in use, a pulse duration of the pulse of the laser treatment beam which is longer than the thermal relaxation time of the first 23a and the second 23b skin region. By predetermining and/or controlling the dimensions of the third skin region 23c, a suitably dimensioned heat sink is created, centrally located within the region being heated by the laser treatment beam, and used to avoid temperature hot spots in the outer layers of the skin.

摘要： The invention provides a non-invasive device for treatment of skin (30) using laser light, the device comprising: an optical system (10) having a laser light source (20) for generating a light beam (21), an opening (13) allowing the light beam (21) to exit the device, and an optical component (12) configured to radially polarize the light beam (21) exiting the device; the optical system (10) being configured such that, in use, the exiting light beam (21) impinges on the outer surface of the skin (30) to be treated, and the device being configured to focus, in use, the light beam (21) at a treatment location inside the skin,whereby Laser Induced Optical Breakdown is induced at the treatment location. The invention also provides a corresponding method to treat skin (30), in particular to reduce wrinkles. The use of the radially-polarizing optical element (radial polarizer) allows a reduction in intensity of the pulse energy in the focal area to produce LIOB. This means that the same level of skin treatment may be obtained with less risk of collateral damage to the tissue surrounding the treatment area
