Wherein, above-mentioned encoder is specially rotary encoder, and the interval in operating between two row light beams is compiled with rotation
The precision of code device is inversely proportional, is directly proportional to roller radius size.Such as：The rotary encoder of same precision, roller radius are got over
Greatly, the distance rolled across is bigger, i.e., the distance between two row light beams are bigger, and vice versa.Such as ensure roller radius size not
Becoming, the rotary encoder precision of use is higher, then each roller turns over that angle is smaller, and often the interval between row light beam is with regard to smaller,
Vice versa.
Operating process is now described with a specific embodiment：User's selection goes out light energy for 10mJ, and light extraction length is 20mm,
It is 3mm per distance between two points, it is assumed that the light extraction time is 20mS when machine output light energy is 10mJ, and each spot diameter size is
0.3mm.Then under normal circumstances, exportable laser of often going, which is counted, is：
Laser points=(- the first spot diameter of light extraction length)/(distance between two points+each spot diameter)+1, i.e.,：
The ≈ 7 (individual) of laser points=(20-0.3)/(3+0.3)+1
It is the time required to normal 7 points of output of row often then：
7 × 20mS=140mS.
It is assumed that：Current location roller output signal is high level, then when roller is rolled into next position, roller output letter
Number it is low level, processor calculates the interval of roller change.
When interval is more than 140mS calculated above, the exportable 7 whole hot spots of machine on this journey；It is small when being spaced
When 140mS, it is assumed that be 100mS, then machine can only export 100/20=5 hot spot on this journey.
