Fujitsu Develops World's First Super-Wide-Angle 3D Laser Radar with a Horizontal and Vertical Range of 140 Degrees

Fujitsu Laboratories Limited today announced that it has developed a super-wide-angle 3D laser radar with more than double the range (140 degrees both horizontally and vertically) of conventional radars.

Ultrasonic wave sensors are already in commercial use in systems that support vehicle parking, for example, to assist drivers when the car is backing into a parking space. However, the detection range is narrow, and multiple sensors were required to widen the area of visibility around a car. By developing a scanning angle expansion lens for the laser beam and a high speed, multipoint laser scanning system for detecting a wide range at high speeds, Fujitsu Laboratories has now roughly doubled the detection range compared to previous sensors to approximately 140 degrees, both horizontally and vertically.

Through the use of a high speed laser scanning system that employs a high speed laser driving circuit and a MEMS (Micro Electro Mechanical Systems) mirror, a high speed, multipoint scanning system has been developed that enables 3D measurement at QVGA resolution of 76,800 pixels (320 × 240) across a detection range of 140 × 140 degrees horizontally and vertically.

As a result, objects can be detected in three dimensions over a wide range with fewer sensors and a sophisticated vehicle backing support system can be created. Moreover, in contrast to vehicle-mounted cameras, which simply display a vehicle’s surroundings, the technology enables systems that detect when objects are abnormally close. It also provides warnings to drivers when backing up a vehicle, which is when accidents are more likely to occur, or when backing into a parking space, which is difficult for many drivers. It is hoped, therefore, that this technology can contribute to safer and more secure driving.
