US 12,585,105 B2 · Apparatus, methods and computer programs for providing control signals for laser scanning systems

Abstract

Examples of the disclosure relate to apparatus for providing control signals to an adjustable mirror in optical systems such as laser scanning systems. The optical systems could be LiDAR systems or optical coherence tomography (OCT) systems or any other suitable systems. The apparatus comprises means for providing a control signal to at least one adjustable mirror to control movement of the at least one adjustable mirror where the at least one adjustable mirror is provided within a laser scanning system. The control signal comprises a multi-step signal where step widths of the multi-step signal are based on half of a period of oscillation of the at least one adjustable mirror.

Dependent claims

An apparatus comprising:

at least one processor;
and
at least one memory including computer program code, the at least one memory and the computer program code configured to, when executed by the at least one processor, cause the apparatus at least to:
provide a control signal to at least one adjustable mirror to control movement of the at least one adjustable mirror where the at least one adjustable mirror is provided within a laser scanning system;
wherein the control signal comprises a multi-step signal where step widths of the multi-step signal are based on half of a period of oscillation of the at least one adjustable mirror, and one or more steps of the multi-step signal has a first amplitude and one or more of the steps has a second amplitude that is different from the first amplitude.
