Patent ID: 8085394

Claim:
An optoelectronic attitude measurement method for determining an attitude of a code carrier which carries a position code and is moveable relative to a detection element with one degree of freedom, the detection element having, in the longitudinal direction, at least one line having a multiplicity of linearly arranged photosensitive reception regions, the method comprising: producing a projection of a part of the position code, depending on the attitude of the code carrier, on the detection element, the production including: emission of optical radiation to the code carrier by means of a laser diode having an emitter edge; and detection of the projection by the detection element; and deriving the attitude of the code carrier relative to the detection element from the projection, wherein the divergence axis of the laser diode emission which is perpendicular to the emitter edge is oriented substantially parallel to the longitudinal axis of the detection element in the case of the projection produced thereby on the detection element.
