Abstract:
A laser shaving device (1) comprising a housing (2) having a skin engaging face (4) and a recess (6) extending into the housing (2) from said skin engaging face (4). The skin engaging face (4) lying in or intersecting a plane (8) that extends across the recess (6) and being positionable against a skin surface (5) such that the skin surface (5) assumes a substantially domed-shape extending in a direction out of the plane (8) of the skin engaging face (4) into the recess (6). The laser shaving device (1) further comprises an optical system (12) configured to direct a laser beam (14) across said recess (6) to cut hairs (10) extending from said skin surface (5) within the recess (6) into a cutting section (15) of the laser beam (14), a skin surface sensor (42) configured to generate a signal indicative of a distance (Yskin(z)) that a skin surface (5) has extended out of the plane (8) of the skin engaging face (4) into the recess (6), and a controller (30) configured to activate the laser beam (14) only if said distance (Yskin(z)) by which a skin surface (5) has extended out of the plane (8) of the skin engaging face (4) into the recess (6) exceeds a distance between said plane (8) of the skin engaging face (4) and a predetermined laser beam activation threshold (Ythreshold(z)).
