METHOD FOR MULTI-TARGET-ENABLED RESOLUTION OF PHASE AMBIGUITY

摘要

The method involves sending periodic signal e.g. light or acoustic wave, to a target object (3) within ambiguity intervals, and receiving signals reflected from the target object. Phases are derived as phase displacement for wavelength of the received signal. The ambiguity intervals are partitioned in cells (5) defined width. Counter reading is incremented for the cells which are arranged to a target distance. An absolute phase is determined for wavelength and/or distance to a target object. Independent claims are also included for: (1) a computer program product with program codes for execution of a method for resolving phase ambiguity; and (2) a distance measurer with a signal source.
