Electricpolarization

Eyeware and Melexis have joined forces to create an advanced driver monitoring system (DMS). This collaboration demonstrates the robustness and wider range of head movement that can be achieved using Time-of-Flight technology, compared with current driver monitoring systems.

Industrial e-vehicles only function well if a number of sensors keep an eye on battery management, actuator positions and people safety around the vehicle. Melexis has been very industrious designing the right ICs for this market.

The MLX75027 is a true VGA fully integrated optical time-of-flight (ToF) sensor IC. The sensor enables the design of very compact 3D cameras.

Sensors are the robot's eyes and ears, whereas actuators make sure robots can move. Melexis can even give them a sense of touch. Sense, comprehend and act. That's what our ICs do.

Polarization of light

Light waves are transverse: that is, the vibrating electric vector associated with each wave is perpendicular to the direction of propagation. A beam of unpolarized light consists of waves moving in the same direction with their electric vectors pointed in random orientations about the axis of propagation. Plane polarized light consists of waves in which the direction of vibration is the same for all waves. In circular polarization the electric vector rotates about the direction of propagation as the wave progresses. Light may be polarized by reflection or by passing it through filters, such as certain crystals, that transmit vibration in one plane but not in others.

Your smart building needs intelligent solutions for comfort, security and management. Thanks to Melexis ICs you keep track of temperature, room occupancy and power consumption. Now that’s smart.

Time-of-flight is gaining popularity in several domains such as the automotive (both interior and exterior use cases) and the industrial domain, but also in smart applications (e.g. smart vacuum cleaner). This webinar clarifies the concepts you need to know to understand the technology behind continuous-wave time-of-flight (cwToF), and especially the principle of the pixel. We also provide an overview of the cwToF system and recommendations to get started. The webinar is accessible to everyone with an interest in time-of-flight technology and visuals and animations are added to facilitate the explanations.

During his online presentation at Autosens in September 2020, regional marketing manager for time-of-flight solutions at Melexis, Cliff De Locht, tells us more about the newest evolutions in time-of-flight (ToF) technology and the automotive interior sensing use cases this enables: you will learn about driver monitoring system (DMS) performance based on ToF cameras (world’s first ToF based DMS demonstrator) and emerging in-cabin monitoring (ICM) use cases with ToF cameras (world’s first “wide-FOV” ToF based ICM demonstrator).

polarization, property of certain electromagnetic radiations in which the direction and magnitude of the vibrating electric field are related in a specified way.

The targeted applications include automotive driver monitoring (DMS), in-cabin monitoring (ICM), exterior cocooning as well as robotics, autonomous transport (AGVs), people and 3D object detection in industry, retail, logistics and smart cities.

The MLX75027 time-of-flight (ToF) sensor delivers precise depth and IR sensing at true VGA (640x480) resolution with frame rates up to 120 FPS. It is ideal for automotive and industrial applications.

Keep an eye on Melexis ICs for security cameras. They enable thermal imaging, people detection and camera motion. Designed for robustness, they keep operating under the harshest of conditions.
