<p>Light source for an optical detector of the position of a body, the latter being measured by the relative position(s) of spots of light projected by the source on a linear detection element. Said source is in the form of a flat luminous geometric figure comprising a curve (23, 23', 24, 24') symmetrical about an axis (22). Said curve is symmetrical about an other 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 said axis. Application to an optical device for measuring the angular position of a body.</p> |
