Abstract:
An example time-of-flight device may include an emitter component configured to emit a plurality of modulated signals toward an object during a transmission window, wherein the plurality of modulated signals emitted during the transmission window are to be used to determine a single distance measurement associated with the object and the time-of-flight device. The time-of-flight device may include a control component configured to cause, via the emitter component, emission of a first modulated signal and emission of a second modulated signal, of the plurality of modulated signals, toward the object, wherein the first modulated signal is emitted during a first portion of the transmission window and has a first phase of a plurality of preconfigured phases, and wherein the second modulated signal is emitted during a second portion of the transmission window and has a second phase of the plurality of preconfigured phases; and cause, using the emission of the first modulated signal and the emission of the second modulated signal during the transmission window, an emulation of a transmission of a measurement signal that has a measurement phase defined based on the first phase and the second phase, wherein the measurement phase is different from the first phase and the second phase.
