We changed the Gap of ToF sensor and Glass in the state of the following photo, and detected the paper (Black, Gray, White) on Glass and confirmed Closstalk Ref Rate.
在下圖的狀態下更改了ToF傳感器和玻璃的間隙,並檢測到玻璃上的紙張(黑色,灰色,白色)並確認了Closstalk Ref Rate。
Result:
It can detect the presence of paper up to Gap 1.5 mm.
However, due to sensor design, Optical design should be made so that the gap between ToF sensor and Glass is 1 mm or less.
結果:
它可以檢測紙張的存在,最大間隙為1.5 mm。
但是,由於傳感器設計,應進行光學設計,使ToF傳感器與玻璃之間的間隙為1 mm或更小。
Closstalk ref Rate is a value that compensates for distance fluctuation due to Closstalk from glass. Based on the design of the sensor, we regulate optical design to be 0.07 or less.
Closstalk ref Rate是一個補償因玻璃Closstalk引起的距離波動的值。 基於傳感器的設計,我們將光學設計調節為0.07或更小。
