Luminous source for an optical detector and optical measuring apparatus utilising said source

摘要

light source for optical position detector has a body, as measured by the relative positions of the light from the source tasks on a linear feature detection, a source in the form of a geometric figure of light flat components a curve (23 23u2032 focussed, 24, 24u2032) symmetrical about an axis (22).characterised in that the curve is symmetrical about a second axis (21) and at least a first thickness (eu2081) to one side of a first (21) of the two axes, and at least a second thickness (eu2082) on the other side of the axis.;application in optical device for angular measurement of the position of a body.
