Abstract

Die Erfindung betrifft eine Vorrichtung zur ortsaufgelösten Objektentfernungsbestimmung mit einer frequenzverschoben rückgekoppelten Strahlungsquelle zur Objektbestrahlung mit entfernungsbestimmungsnutzbarer Strahlung und einem positi­onsempfindlichen Objekterfassungssensor. Hierbei ist vorgese­hen, daß die frequenzverschoben rückgekoppelte Strahlungs­quelle zur Objektbestrahlung mit einem Mittel zur Emissionsfrequenzkomponentenschwebungsintensitätserhöhung und der positionsempfindliche Objekterfassungssensor zur Erfassung der Schwebungsintensität vom Objekt und nicht-vom Objekt einlau­fender Strahlung ausgebildet ist.
