Scalable Approach to Lidar Could Propel Autonomous Vehicles, Other Tech

Facebook X LinkedIn Email
A silicon chip with a serpentine optical phased array (SOPA), developed by researchers at the University of Colorado Boulder, could improve the resolution and scanning speed of lidar systems while reducing bulkiness, making them scalable for a range of applications. The SOPA is based on an array of low-loss grating waveguides and supports passive, 2D wavelength-controlled beam steering. The beams are controlled by changing wavelengths. Multiple phased arrays can be controlled simultaneously to create a bigger aperture and a higher-resolution image. Compact, wavelength-steered tiles are...Read full article

    lidar
    Lidar, short for light detection and ranging, is a remote sensing technology that uses laser light to measure distances and generate precise, three-dimensional information about the shape and characteristics of objects and surfaces. Lidar systems typically consist of a laser scanner, a GPS receiver, and an inertial measurement unit (IMU), all integrated into a single system. Here is how lidar works: Laser emission: A laser emits laser pulses, often in the form of rapid and repetitive laser...
    integrated photonics
    Integrated photonics is a field of study and technology that involves the integration of optical components, such as lasers, modulators, detectors, and waveguides, on a single chip or substrate. The goal of integrated photonics is to miniaturize and consolidate optical elements in a manner similar to the integration of electronic components on a microchip in traditional integrated circuits. Key aspects of integrated photonics include: Miniaturization: Integrated photonics aims to reduce the...
