Various implementations disclosed herein include a method for operating a LIDAR sensor, comprising repeatedly performing measurements in a respective measurement time window (M), at the beginning of which at least one measurement light pulse (A) having at least one predefined wavelength is emitted by the LIDAR sensor, and determining whether a light pulse (A′) having the at least one predefined wavelength is detected by the LIDAR sensor within the measurement time window (M), wherein a time interval (D1, D2, D3) between two consecutive measurement time windows (M) is varied.

The present disclosure generally pertains to time-of-flight imaging circuitry configured to: control a set of readout channels for an imaging element for obtaining a set of events representing a set of light pulses captured in the imaging element, wherein the controlling includes: a first detection of the set of events in a first readout channel of the set of readout channels; and a second detection in a second readout channel, wherein the second detection starts a predetermined time after a start of the first detection for detecting a subset of the events.

A sensing system comprising an emitter configured to emit electromagnetic radiation, a detector configured to detect electromagnetic radiation and an electronic component configured to interact with a circuitry of the sensing system. The electronic component is located at least partially between the emitter and the detector. The electronic component reduces an amount of electromagnetic radiation propagating from the emitter to the detector. The electronic component advantageously reduces the unwanted detection of electromagnetic radiation that would otherwise propagate directly from the emitter to the detector without leaving the sensing system, thereby reducing a measurement noise and improving an accuracy of the sensing system. The sensing system may form part of a time-of-flight sensing system or a proximity sensing system. The sensing system may form part of an electronic device such as a mobile phone.

A method for detecting lost image information via a lighting device and an optical sensor. The lighting device and the optical sensor are controlled so as to be chronologically aligned with each other. A visible spacing region in an observation region of the optical sensor is determined from the chronological alignment of the control of the lighting device and the optical sensor. A recording of the observation region with the optical sensor is generated via the aligned control. Image information is identified in the recording in regions outside of the spacing region visible in the image, so as to make the identified image information accessible.

The light wave distance meter is disclosed, including: a distance measuring light-emitting unit; a light-receiving signal generating unit; and a control arithmetic unit. A light-receiving signal includes a first intermittent light-receiving signal corresponding to a first distance measuring light, a second intermittent light-receiving signal corresponding to a second distance measuring light, a third intermittent light-receiving signal corresponding to a third distance measuring light, and a fourth intermittent light-receiving signal corresponding to a fourth distance measuring light. The control arithmetic unit executes an error determination control to acquire a shift signal generated by shifting at least a phase of any one of the first to fourth intermittent light-receiving signals by 2π.Math.n−π/2 or 2π.Math.n+π/2, and compares the phase of the shift signal and the phase of the intermittent light-receiving signal at least between either the first frequencies or between the second frequencies.
