Method and device for optical distance measurement

A method for optical distance measurement, comprising the steps of:

• transmitting measuring pulses by means of a transmission matrix comprising a plurality of transmission elements;
• reflecting transmitted measuring pulses on at least one object;
• and
• receiving reflected measuring pulses by means of a reception matrix comprising a plurality of reception elements each having a plurality of reception sub-elements;
• and
• monitoring reception rates of reception sub-elements of the reception matrix for determining a misalignment between the transmission matrix and the reception matrix;
• wherein the transmission matrix and reception matrix define a visual field;
• wherein the method is used for the navigation of a vehicle, wherein the monitoring takes place while a vehicle is traveling;
• and
• wherein the method does not involve the conscious introduction of measuring objects into the visual field for determining a misalignment,
• wherein the reception elements are pixels, and the reception sub-elements are subpixels.
