of light emitting part and signal receiving part: light emitting part composed of optic LED 

and collimation lens, signal receiving part composed  of hartman plate and 2-dimentional 

CMOS sensor. The followings are the components of each part:   

 

 

Light Emitting Part   

- 

Optic LED   

: 525nm 

- 

Ball Lens 

: condenses the light radiated from Optic LED. 

- 

Rubber Ring 

: fix ball lens.   

- 

Scatter  

: disperse the optic LED light
