For obstacle detection and classification, there are currently applications of vision and laser pointer radar, which do not conflict. Lidar does not depend on light, its angle of view is 360 degrees, the calculation is relatively small, and it can be scanned in real time. At present, it is generally used within 100 milliseconds. During the scanning…

The Main Research And Development Efforts Are Also Focused on Laser Pointer Radar
For non-scanning laser radar, Flash LiDAR is a scanning laser pointer radar, which emits an area of light. For example, Ledder Tech in Switzerland developed products such as Flash liDAR. At present, in fact, the industry’s current driving force is quite large, including ourselves, and the main research and development efforts are also focused on solid-state lidar….
Lidar is Essential For Autonomous Driving
Lidar is an indispensable laser pointer sensor for autonomous driving. The system framework of the partial algorithm layer for unmanned driving. The acquisition of high-precision maps relies heavily on lidar and cameras. After obtaining high-precision maps, we combined GPS and IMU, encoders, and real-time perception of the environment to perform map matching and positioning. For path planning…
Using quantum cascade laser pointer to form standing wave
To solve the problem. The research team adopted a completely new structural design. The quantum cascade laser pointer is used to form a “standing wave” and add cracks in the standing wave so that the terahertz laser can rush out of the waveguide and coincide with the band in the opposite direction to increase the laser intensity….
New method of lidar to see the truth behind
It is understood that in addition to autonomous driving, land survey is also one of the main applications of laser pointer radar. However, due to the influence of environmental factors, it is inevitable that the laser radar will have some blurring effects in the land survey. Recently, the US Naval Research Laboratory in Washington, DC, proposed a…
Tong laser pointer radar uses a monochromatic laser
By collecting these optical information, information on their component distribution and Fengdu can be obtained, helping the environmental protection department to grasp in-depth and detailed atmospheric composition information and give corresponding countermeasures. The ordinary laser pointer radar uses a monochromatic laser as a detection source, which can only generate strong scattering effects with specific atmospheric molecules, while…
Refractive index sensing based on semiconductor nanowire laser
The manufacturing process uses a semiconductor-like laser pointer process in which cadmium sulfide (CdS) nanowires (refractive index n = 2.67) are grown on a silicon wafer substrate using chemical vapor transport. After that, the nanowires were directly deposited on the silicon glass cover, and then exposed to low pressure plasma. This plasma treatment is used to ensure…
Basic laser pointer physical parameters measured
Most engineers are familiar with the basic laser pointer physical parameters that need to be measured, such as temperature, pressure, position, speed, and distance. But there are other key parameters that are also very important. An example of this is the measurement of light refractive index (RI), which is also part of many liquid processing processes, such…
Green laser pointer has been provided to the environmental protection department
Multi-modal bioimaging and analysis: Due to the complex and diverse response of human cells, tissues and organs to light, and their sensitive wavelength bands are also diverse, the laser pointer with variable wavelength, super continuous, ultra wide band and high power is especially needed as a tool , Using optical coherence tomography, Raman spectroscopy, non-linear spectroscopy, and…
White light laser pointer spectrum range
Chemical molecular reaction dynamics: The time scale of chemical molecular reaction dynamics ranges from a few picoseconds to a few femtoseconds. The spectral range of the white light laser pointer is far beyond that of the general titanium sapphire femtosecond pulse laser. These coherent spectral components can produce laser pulses as short as one femtosecond through coherent…
