US 2026/0016595 A1 · METHOD AND APPARATUS FOR MULTI-RANGE TIME OF FLIGHT DETECTION

Abstract

A method for detecting distance of a distant object is provided. The method includes sending at least one first pulse of light towards an object, the at least one first pulse having a first pulse width configured to detect objects at a first range of distances, detecting within at least one first time slot the first pulse reflected by objects within the first range; sending at least one second pulse of light towards the object, the at least one second pulse having a second pulse width configured to detect objects at a second range of distances. The method further includes detecting within a second time slot the second pulse reflected by objects within the second range and determining distance of the object in accordance with the detection of the first and second pulses.
