Abstract: The invention relates to a system and method for removing hair. The hair removal system comprises a hair detection device and a hair removal device (20; S3) operatively coupled to the hair detection device, wherein the hair detection device comprises an imaging device comprising a first image sensor (12; S1) which is constructed and arranged to detect an image of a part of a skin (30) to be treated, and a control unit (18) adapted to discern, in the image, a hair (32) on the part of the skin (30), and operatively coupled to the hair removal device (20; S3) so as to control its operation, characterized by preventing means coupled to the control unit (18) and being adapted to disable the hair detection device or the hair removal device during a preventing period after the control unit has discerned the respective hair for the first time.

Abstract: There is provided a device for imaging a skin object (7) near a skin surface of a body part, comprising a light source (1) and a detector (8) for detecting radiation returning from said object (7), wherein the device further comprises an elliptical, preferably circular, polarizer (4, 19) between the source (1) and said skin (6) surface, the device comprising a 5 ratio increaser means (3, 4, 19) for increasing the ratio of radiation from said object (7) to radiation from said skin (6) surface. The ratio increaser may be an additional or the same elliptical polarizer. Using elliptically or even circularly polarized light makes hair detection independent of the orientation of hair (7) with respect to light or polarization, which renders 10 the detection more reliable. The invention also provides an imaging method and a hair-shortening device and method.

Abstract: A method and system for detecting blood vessels and precisely determining parameters in respect thereof, such as geometry, depth and diameter. Optical imaging, such as IR imaging, is used to obtain a general overview (16) of the blood vessel pattern in a region of interest from which a target vessel can be defined and its lateral position determined. Ultrasound imaging is then employed to precisely measure parameters, such as depth and diameter, in respect of the target vessel. The resultant system is of relatively low cost, and relatively simple to implement and use.
