The MLX75023 is a QVGA (320 x 240 pixels) resolution optical time-of-flight (TOF) camera sensor. Combined with a modulated light source, this sensor is capable of measuring distance and reflectivity at full resolution.

The high dynamic range DepthSense™ TOF pixels support up to 120 klux background light. The sensor is available in a chip scale glass ball grid array (BGA) package and offers many integration possibilities.

Melexis' time-of-flight sensors enable robust 3D imaging solutions with minimal post-processing cost and large scalability of resolution, range and field-of-view. Our MLX75023 engineering samples and reference application schematic are available on request.

Car passenger detection

Application

Combined with a modulated light source, the MLX75023 optical Time-of-Flight camera sensor IC is capable of measuring distance and reflectivity at full resolution, offering many integration possibilities.

Occupancy and steering wheel hands on/off detection (side view)

Application

This demo presents a Time-of-Flight (non-capacitive) steering wheel hands on/off detection, body pose, movement and occupancy detection, which can address solutions that support partially to fully autonomous driving. The Time-of-Flight camera is positioned near the roof module and the 3D view is rotated to show a side view of the driver.

Real-time body pose detection (frontal view)

Application

This demo shows detection of the driver hand(s) on the steering wheel as well as a body pose detection, which can address solutions that support partially to fully autonomous driving. The Time-of-Flight (ToF) camera is positioned near the roof module and the 3D view is rotated to show a frontal view of the driver.
