High-precision turntable supporting quantitative evaluation of beam characteristics (compatible with ultrasonic sensors, microphone arrays, etc.)
Our company's remote-controlled turntable for directional measurement allows for the rotation of the measurement target device to a specified angle before and during measurement, enabling direction-dependent measurements. It is utilized not only for acoustic applications but also by customers in the security field for research and development of security sensors. The following applications are considered: - Security field for home and automotive: intrusion detection using ultrasonic sensors, crime prevention, smart home alarms, etc. - Conference microphone arrays and beamforming technology. - For research institutions, acoustic sensing research, beamforming research, etc. - Other applications include directional evaluation of microphone arrays, directional characteristic evaluation of AI acoustic analysis sensors, verification of beamforming performance, and accuracy evaluation of direction of arrival (DOA) estimation.
