If one day you get in a car without a driver, it's steady away from pedestrians and it's accurate enough to get into traffic — how does it “see” the world? The answer lies in the little hat that rotates on the top of the car, and in the depths of this little hat there is a much less visible character, the laser diode。
Laser diodes
It works like a bat
The idea of laser radar is the same as that of bats: constant lasers are fired, the light hits pedestrians and vehicles are reflected back and range is measured by calculating “how long it took for the light to travel”. It's just the hard work of the rolling king class — sending hundreds of thousands of lasers every second, spinning and scanning, and in a few milliseconds, you can “brush” the world around 360 degrees and 100 metres into a fine three-dimensional cloud map. Every car on the road, every pedestrian, and even a cat that comes out of nowhere, will not escape its “methods”。
The source of each light is a laser diode. Pipe
Many do not know that each laser launched by the laser radar is sourced from a laser diode of rice grain size. Its performance directly determines the radar's “vision”: light beams are small enough, power is unstable, and can withstand tens of degrees of temperature differentials and hundreds of millions of switches in the car environment。
In the case of the korean qsi, full-process autonomous manufacturing capability from exterior (epi), crystal round processing (fab) to containment (pkg), with a product wavelength ranging from 635 nm, 650 nm red light to 780 nm, 808 nm, 905 nm infrared band, is widely used in the areas of bar code scanning, laser rangers, horizontal machines, industrial sensors and proximity. It's possible to say that from your house's sweep robots, the grader used for the renovation, to the distance from the factorySensorsThe same technology is shining behind it。
Three, something bigger than a human eye
The camera is a “level eye”, which is easily “eye flower” when it comes to night, heavy rain, and reverse light; laser radars measure distance and reach a cm level of precision. For example, the camera said, “there seems to be a man ahead”, while the laser radar said, “there is a moving target of 1. 75 metres above 23. 5 metres ahead”. This certainty is the bottom of safety at tens of metres per second。
Iv. Spectrogenic light sources that require reliable partners
For laser radars, range gauges and sensors, the selection of laser diode suppliers is essential. In the field of deep-drive lasers, shenzhen city ltd., for more than 10 years, was the original agent of the large chinese region of the qsi laser diode in korea。
The strength of rhonda is:
(a) direct supply: full series of original qsis, quality and endorsement after sale
Complete: 635 nm-980 nm multiband, 5 mw-1w multipower specification, long-term spot
Professional services: provide process-based technical support from selection, sample to bulk delivery。
Through the concept of “prior to branding, hard-core service”, ryuhing has served manufacturers and research institutes in a wide range of fields, including measurement instruments, bar-code scanning, medical equipment, laser sensing, etc。
