Abstract
A method for optical distance measurement is provided, which comprises emitting a plurality of measurement pulses, reflecting emitted measurement pulses on at least one object within a measurement range with a length and receiving reflected measurement pulses. N subsets of measurement pulses are emitted, wherein each subset comprises a constant pulse interval. The constant pulse interval of different subsets is different, wherein the least common multiple of the constant pulse intervals of the N subsets corresponds to at least twice the length of the measurement range.
Claims15
A method for optical distance measurement,
- wherein the method comprises emitting a plurality of measurement pulses, the reflection of emitted measurement pulses on at least one object within a measurement range with a length and receiving reflected measurement pulses,
- wherein N subsets of measurement pulses are emitted,
- wherein each subset comprises a constant pulse interval,
- wherein the constant pulse interval of the different subsets is different,
- wherein the least common multiple of constant pulse intervals of the N subsets corresponds to at least twice the length of the measurement range.
A device for optical distance measurement,
- wherein the device is designed as a LIDAR sensor and comprises a transmitting unit for transmitting measurement pulses and a receiving unit for receiving reflected measurement pulses, wherein the device is designed to carry out a method for optical distance measurement,
- wherein the method comprises emitting a plurality of measurement pulses, the reflection of emitted measurement pulses on at least one object within a measurement range with a length and receiving reflected measurement pulses,
- wherein N subsets of measurement pulses are emitted,
- wherein each subset comprises a constant pulse interval,
- wherein the constant pulse interval of the different subsets is different,
- wherein the least common multiple of constant pulse intervals of the N subsets corresponds to at least twice the length of the measurement range.
