  • MLX75026 with a fully integrated IR filter improves system stray light performances

    Tessenderlo, Belgium, 15 September 2021 - Melexis has developed a new version of its time-of-flight 3D camera MLX75026 with a fully integrated infrared bandpass (IRBP) filter. By integrating the IRBP, it is no longer required to include a separate IR filter in the lens or sensor assembly. This solution is unique in the industry. It reduces design complexity and cost, while creating more design choice when sourcing a lens.

    Melexis, a global microelectronics engineering company, has introduced the MLX75026 with IRBP, an AEC-Q100 qualified QVGA time-of-flight sensor that further expands the third generation of ToF sensors from Melexis. The integration of an infrared bandpass filter removes the need to add a separate bandpass filter, which simplifies design and manufacturing while also increasing the choice of suitable, IR-friendly lenses.

    The MLX75026 targets automotive use cases like driver monitoring (DMS), in-cabin monitoring, gesture control, safety applications related to airbag deployment, head-up display (HUD) driver alignment and industrial applications like automated guided vehicles (AGVs), elevator entry and (collaborative) robotics.

    “An IR filter is mandatory in every ToF application to reduce out-of-band infrared light in the operating environment, which could otherwise lower the dynamic range of the sensor,” explained Gualtiero Bagnuoli, Optical sensors marketing manager at Melexis. “A separate filter adds cost and complexity to a design, but by using the MLX75026 with IRBP filter, engineers can avoid both the cost and complexity, and explore the benefits of time-of-flight sensing more easily”.

    The integration of the correct IR bandpass filter is not trivial: the passband must be adapted to the illumination and the filter shall accept light from a wide range of incidence at minimal spectral shift (optically hard filter). This facilitates the usage of ToF-lenses with high apertures (low f-number). Melexis is the only ToF sensor manufacturer currently offering this option, which is now available as a variant of the MLX75026. The MLX75026 offers software-compatibility with other Melexis gen 3 ToF sensors.

    MLX75026 with IRBP filter has QVGA (320x240 pixels) resolution with a 1/4 inch optical format and supports 940 nm illumination. Configuration is implemented over an I2C interface and provides CSI-2 serial data output. The high integration, small size and low power consumption of the sensor, coupled with the integration of the IR bandpass filters, enables the design of compact and cost-effective ToF cameras for automotive, industrial and consumer applications.

    Samples of the MLX75026 with IRBP filter are available now. A compact high-performance evaluation kit (EVK) will also be released.

    Incorporating a Xilinx Zynq Ultrascale+ MPSoC, the EVK75026+ quadruples the data bandwidth and frame rate of the earlier EVK75026 evaluation kit, while taking up approximately half the mechanical size. It offers advanced pixel calibration and filtering functions, plus on-demand support for sophisticated features like ambiguous range extension, multi-path resolving and interference rejection. The programming interface (API), written in C language, includes wrappers that allow the kit to be used with both Matlab and Python.

  • Time-of-flight (ToF) technologies are rapidly gaining momentum for interior and exterior sensing automotive applications

    Examples of safety functions include NCAP mandated driver fatigue detection, and occupancy/child seat detection for more precise airbag control. Additional safety functions like hands-on-wheel detection, eye gaze, head pose, body pose and advanced seat-belt application are possible with the same ToF camera.

    Comfort functions supported by ToF include hand position interaction (intuitive HMI) to operate the sunroof, airco and radio; personalization through body, head and face monitoring; detection of objects left behind in the vehicle; and parcel classification and recognition. In-car security functions generally focus on anti-spoof face detection for trusted driver identification and on-route payment authorization.

    Looking into exterior sensing applications of ToF technologies, the continuing expansion of autonomous driving makes it increasingly apparent that traditional 2D cameras will be complemented by RADAR, LiDAR, stereo cameras, thermal cameras, short wavelength infrared cameras and/or ToF cameras. The right arsenal of sensors will be able to cover the “blind spots” that can occur in an automotive environment. Exterior use cases for ToF technology include short-range ADAS exterior cocooning and advanced parking assist.

    Melexis is at the forefront of such developments and in particular fully confirms the appropriateness of continuous wave ToF for in-cabin applications. We designed and manufactured the first automotive qualified ToF sensor, which entered volume production in 2015. Just four years later we reached the impressive milestone of having more than one million ToF 3D camera ICs on the road, proving the maturity of this technology in automotive.
