Design concept

Through the optical telescope lens focus on the object after the

focal length, and then use the high reflector to reflect the

cross-line scale and the scale on the eyepiece to compare

the difference between the coordinates obtained by drawing

the curve.

Ruler design

The system is designed with two optical crosshair scribes that

 are collapsed by parallel optical reflection using a 0.5 second

 micrometer compared to their coordinates and then plot the

 data to the chart geometric compensation linearity (X ruler)

 and plane (Y scale).

Instrument features

* 6 B : Visual field type observation

     < General occasions apply >

* 6 D : Dark vision type observation

     < Backlit, low reflective plane or small plane mirror >

* Accurate measurement of the same distance X / Y

  coordinate difference, and at the same time to draw

  the measured coordinate data.

* Focal length compensation adjustment equipment;

  up / down / left / right fine adjustment mechanism.

* High efficiency determination - No stable environmental

  factors are used in the field and no determination of the

  action or impact measurement accuracy due to movement

  of the person.
