Which is better red dot or laser pointer?

How long does it take for the laser beam to hit Mars from Earth’s orbit? Well, the laser pointer beam travels at approximately 186,282 miles per second, so you can calculate the time by dividing the distance by this value. I have posted the approximate maximum and minimum distances between the planets and the sun, and placed…

Larger better and larger laser pointer

How practical is the laser gun? it depends. Using the currently imaginable technology, anywhere between “very” and “worse than useless” let us start from the very practical. That is a laser pointer mounted on a large object, such as a ship or air defense system, which can provide power and cooling. Laser Weapon System-Wikipedia The US Navy…

If the laser beam can travel at the speed of light

What will happen to people who are hit by a laser pointer blaster (Star Wars)? Unlike an ancient laser pointer that emits a coherent beam, the blaster emits a beam of superheated plasma, or a beam of self-sufficient high-energy particles, depending on who you are asking. The most powerful E-11 (standard stormtrooper carbine) can evaporate anything except…

STMicroelectronics launches laser ranging sensor

Across multiple electronic applications, STMicroelectronics, the world’s leading semiconductor supplier, released the second generation of laser pointer ranging sensors. The new sensor VL53L0 is based on the successful FlightSense MT technology to achieve faster, farther, and more accurate ranging functions, greatly improving the camera performance of mobile phones and tablets, for robots, user detection, drones, Internet of…

The huge spaceborne laser pointer weapon is technically difficult

There is no air in space, and SBL does not have the problems of beam refraction, absorption, jitter and thermal blooming in the atmosphere. However, the biggest problem with space laser pointer weapons is sufficient power, and the technical difficulty of deploying massive and bulky spaceborne laser weapons in orbit is too high. , Reliable, controllable, high…

China’s synthetic aperture lidar achieves new progress

There are stories about “clairvoyance” in Chinese mythology, but the eyes of all creatures in nature cannot see the distance of a thousand miles. The development of new technologies, especially the development of synthetic aperture lidar (SAL) technology, may really enable humans to have “clairvoyance” capabilities. It is a high-resolution imaging lidar. Its outstanding feature…

Extract a single light particle from the laser beam

The researchers said that extracting a single light particle from a laser pointer beam may bring a huge breakthrough in quantum computing. Physicists from the Weizmann Institute of Science in Israel successfully extracted a single photon from a single beam of light using ultra-cold atoms and cutting-edge optical technology. Physicists are very interested in individual photons because…

Laser experiments reveal that the moon has a fluid core

What information can scientists gather from the laser pointer light reflected from the lunar reconnaissance orbiter? First, it accurately reveals the time it takes for the photon to go back and forth-2.5 seconds on average. Scientists can use this time to determine the exact distance of an object. At the same time, by measuring tiny fluctuations in…

Global semiconductor laser market outlook and growth analysis

According to relevant data, the global semiconductor laser pointer market will exceed 7.69 billion U.S. dollars by 2020, with a compound growth rate of 7.1% from 2014 to 2020. Semiconductor lasers have been widely used in many fields, including sensors, optical storage devices, health care, industrial machinery manufacturing, communications, lithography, and national defense. Among them, communication applications…

A brief talk on the application of laser equipment in the mold industry

With the continuous upgrading of technology, the use of laser pointer processing has become more and more extensive, especially the use of laser processing occasions, especially the large-scale use of laser equipment in automobile, mold, machinery and other processing occasions, especially the advantages of the mold industry The performance is obvious: Large and medium-sized precision molds are…
