An optical blade and a hair cutting device is configured to cut a hair near skin of a human body part or animal body part. The optical blade maybe used in a hair cutting device and includes a blade body configured to guide optical radiation, and a tapered end configured to allow the optical radiation to exit the optical blade. The tapered end includes a reflector configured to redirect the optical radiation before it exits the optical blade.

Optical blade and hair cutting device

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 (; S) operatively coupled to the hair detection device, wherein the hair detection device comprises an imaging device comprising a first image sensor (; S) which is constructed and arranged to detect an image of a part of a skin () to be treated, and a control unit () adapted to discern, in the image, a hair () on the part of the skin (), and operatively coupled to the hair removal device (; S) so as to control its operation, characterized by preventing means coupled to the control unit () 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.

Hair removal system and method

A detector for detecting a birefringent object near a skin surface of a human body part or an animal body part includes a source for emitting optical radiation having first and second wavelengths and an incident polarization state. An imaging unit is configured to image the birefringent object near the surface includes a detection unit for detecting optical radiation scattered and/or reflected by the birefringent object and/or the surface at the first and second wavelengths. A control unit is configured to process a signal from the detection unit for discrimination between the birefringent object and the surface. The detection unit is configured to detect scattered and/or reflected optical radiation coming from the birefringent object and/or the surface, having a first polarization state corresponding to the incident polarization state and a second polarization state being different from the first polarization state.
