A distance measuring arrangement for determining a distance from an object includes at least one light source for producing at least one first monochromatic and interference-capable light beam with a first wavelength and at least one second monochromatic and interference-capable light beam with a second wavelength, a multiplexer for coupling or combining the at least one first light beam and the at least one second light beam into a common measurement beam, an output coupling element for splitting the measurement beam into a reference beam and a signal beam, wherein the reference beam propagates along a reference path and wherein the signal beam propagates along a signal path, and a phase modulator that is arranged in the signal path and configured to modulate the phase of the signal beam periodically in time.
