TITLE OF THE INVENTION "Light source for an optical sensor and optical measuring device using same" TEXT OF THE Light source for an optical sensor for sensing the position of a body as measured by the relative position or positions of light spots from the source on a linear sensing member, the source being in the form of a plane luminous geometrical figure comprising a curve (23, 23', 24, 24') symmetrical relative to an axis (22), characterised in that the curve is symmetrical relative to another axis (21) and has at least a first thickness (e1) on one side of a first (21) of the two axes and at least a second thickness (e2) on the other side of that axis. Application to a device for measuring the angular position of a body. (figure 2) |
