Abstract: An oscillator control system includes an oscillator structure configured to oscillate about first and second rotation axes according to a Lissajous pattern, wherein an oscillation about the second rotation axis imparts a cross-coupling error onto an oscillation about the first rotation axis, and wherein the cross-coupling error changes in accordance with a Lissajous position within the Lissajous pattern; and a driver circuit that includes a phase-locked loop (PLL) configured to regulate a driving signal that drives the oscillation about the first rotation axis. The PLL is configured to generate a PLL signal based on a phase error of the oscillation about the first rotation axis. The PLL includes a compensation circuit configured to receive the PLL signal and the Lissajous position within the Lissajous pattern, apply a compensation value to the PLL signal to generate a compensated PLL signal used for generating the driving signal based on the Lissajous position.

Abstract: A method of Lissajous scanning includes driving a first oscillator structure about a first rotation axis at a first resonance frequency according to a first driving signal, and driving a second oscillator structure about a second rotation axis at a second resonance frequency according to second driving signal different from the first resonance frequency. The first driving signal has a first low level, a first high level, and a first duty cycle, the combination of which produces the first resonance frequency, and the second driving signal has a second low level, a second high level, and a second duty cycle, the combination of which produces the second resonance frequency. At least one of the second low level, the second high level, and the second duty cycle is different from the first low level, the first high level, and the first duty cycle, respectively.

Abstract: A sensor arrangement comprises a communication device and a sensor element. The sensor element is configured to record a property and provide a sensor signal that represents the property. The sensor arrangement comprises a security element configured to provide a secret. The sensor arrangement is configured to link the sensor signal to the secret to obtain a linked sensor signal, transmit the linked sensor signal to a communication partner using the communication device, obtain a test signal from the communication partner using the communication device, and perform a check to determine whether the test signal comprises the secret.

Abstract: An object sensor test system includes a sensor and a test bench. The sensor includes a receiver configured to receive a simulated optical signal and a processing chain that includes a plurality of processing components configured to process at least one measurement signal generated in response to the simulated optical signal to generate processed test data. The sensor also includes a test interface configured to receive a control signal, and selectively extract processed test data at a selected output of the processing chain based on the control signal. The test bench is configured to transmit the control signal to the test interface, receive the processed test data from the sensor, compare the received processed test data with expected data to generate a comparison result, and determine that a segment of the processing chain is operating normally or abnormally based on the comparison result.
