Just like the projector, the light source of the head-up display has gradually changed from traditional light bulbs to LEDs to today’s laser pointer technology. The first laser head-up display first appeared at the Consumer Electronics Show in Las Vegas in 2011. Audi and Pioneer each exhibited this technology. Take Pioneer’s products as an example. It mainly…

Scientists develop new laser pointer materials
Indian scientists have developed a new type of laser pointer material: greatly improving the efficiency of solar power generation. Scientists from the Indian Institute of Science and Technology have designed a new type of laser material that can change the way solar energy is obtained, thereby making solar power generation more efficient. The professor and his team…
Nanophoton frequency converter can realize single photon color conversion
False-color scanning electron micrograph of a nanophotonic frequency converter containing a ring resonator (blue shaded part), and a waveguide (red part) is used to inject light into the ring resonator. The input signal is represented by a purple arrow and converted to a new frequency (blue arrow) by using two pump laser pointer (bright red and dark…
How difficult is it to build a laser pointer spacecraft by Hawking?
The famous British physicist Stephen Hawking has a large number of fans in China. On April 12, as soon as Mr. Hawking’s official Weibo was launched, Chinese netizens went crazy laser pointer, and their fans quickly reached more than 2 million. May I ask who has such an aura? Not only that, Elder Hawking also made…
Facing a very big laser pointer technical problem
Because the light from the sun provides endless energy, a spacecraft with a large solar sail can eventually laser pointer travel at a speed of 240,000 kilometers per hour. This speed is 4-6 times faster than the fastest spacecraft propelled by rockets today. That is, it is 6 times faster than the second universe and 4 times…
Laser pointer technology that will fundamentally change future space communications
The communication problem is not without solutions. Scientists are already conducting experiments on laser pointer communication. Laser communication is 6 times faster than electromagnetic waves. On June 6, 2014, NASA announced that the agency used a laser beam to transmit a high-definition video from the International Space Station back to the ground, successfully completing a technology demonstration…
It can be realized in laser pointer technology first
The project will be led by the former director of NASA Ames Research Center Pete? Warden leads a committee of world-class scientists and engineers to provide advice, and its development may take several years. Although Milner invested 100 million US dollars in advance, the entire laser pointer project research and development may cost 5 to 10 billion…
Ultrafast pulse lasers increase data transmission speed
According to reports, the ultrafast pulsed laser developed by the Korea Institute of Science and Technology produces a frequency 10,000 times higher than the current most advanced pulsed laser pointer. This is achieved by inserting an additional resonator containing graphene into a fiber pulse laser oscillator operating in the femtosecond range. The application of this method…
Adaptive driving beam technology system with universal laser characteristics
The headlights and headlights of vehicles are particularly important for safe driving, especially at night. Adaptive driving beam technology is a good solution. In general, ADB means that the headlights of a car are automatically adjusted according to the speed and driving conditions. ADB can automatically activate the headlights when needed, and then adjust its…
What is the status of high-energy laser weapons in India
According to reports, starting from April 2020, relevant foreign troops have violated the agreement between the two countries by building temporary bridges and building roads when arriving at the border, frequently crossing the border to fight for control, trying to unilaterally change the status quo of border control, leading to a sudden increase in the…
