2023-01-03

"equipment and technology development of people's life convenience". 「 useful devices 」.pulse oximetry와 lidar는 설명되어야 한다. pulse oximetry는 noninvasive device used to measure the oxygen level ofthe blood,clipping this equipment onto a patient'의 핑거.lidar (light detection and ranging),"easy to operate by clipping"an optical technology입니다."a key method for distance sensing for autonomous vehicles"."geographical survey".강 bed elevation, and the density of forests and hills. despite different features, they share one thing in common:they rely on the help of infrared led that emits infrared light invisible to the naked eye.

how do pulse oximetry and lidar work with infrared led


1. pulse oximetry

펄스착색다이오드 (leds):660 nm와 a led, 펄스착색다이오드 (pulse exximetry consists of light emitting diodes)2개의 일을 다르게하고 있다. oxyhemoglobin in the. 2개의 일을 다르게하고 있다블러 드 mainly absorbs infrared light with 표현 ranging from 850 nm to 1000nmwhile deoxyhemoglobin mainly absorbs red light at 600 nm to 750nm. the pulse oximetry is designed to based on thedeoxyhemoglobin at 660nm has higher absorption, principle that deoxyhemoglobin at 660nm has higher absorption,and oxyhemoglobin at 940nm has a higher absorption. then the value of the reflected light intensity collected isthe oxygen level of the blood converted to that of the oxygen level.

 

 

 

2. lidar

레이저, 스캐너, 특수 gps receiver,imu (inertial measurement unit) are the four main components of a lidar system. 「 lidar technology uses infrared 」"led to deliver light pause and receive the reflected light to measure distances to a target"precise distance measurement points each second, producing a 3d matrix of its environment.objects'position, shape, and behavior can be obtained from the comprehensive mapping of the environment.

 

refond's ir led solutions for pulse oximetry and lidar

"refond is cognizant of the increasing demand for pulse oximetry and lidar for led circuits".we introduced advanced infrared led solutions to solve the pain points of industrial applications and meet the"different application scenarios"."here are the infrared led solutions offered by us".

 

1. blood oxygen sensing series

right components, especially infrared led,만약 led driver circuit has noise near dc 가 near dc 일 경우, 신피질 사막화 (oxygen content of blood)의 measurement of the integralcoupled with nonlinearity, it will impact the led brightness,2006년 6월 1일에 확인함."thereby affecting the measurement accuracy of the oxygen level of the blood". 「 ir led for blood oxygen sensing series 」industries long encountered; solve pain points that industries have long encountered;940 nm와 660 nm의 wavelength of easily detect light signal at a wavelength, being a reliable option for pulse oximetry.

clcc series (clcc series).

our infrared led for lidar system boasts the following advantages that make it stand out among its other counterparts.

l feature with hardware filtering and dragging point,which can effectively avoid interference caused by some noise points.

e ="margin-left:21pt,text-align = justify다."l synchronously output the target object reflection intensity, which be used for algorithm measurement.

l ranging accuracy of being equal to or greater than 30mm.

1. different objects-linear characteristics.

l no interference between the radars when the multiple radars operate at the same time.

special optical design, which can effectively improve the anti-dirt performance.


 

 

 

refond's outlook on future

ir led strip has the edge regarding professional packaging capabilities, high power density2013년 6월 13일에 확인함."refond will remain true to our original aspiration".enrich human life bringing innovative technology (영어).develop state-of the-art infrared led solutions을 개발 할 것입니다.advanced proximity light sensors ad uv sensors will be introduced in the foreseeable future.
