LOS雙頻激光干涉儀是以波長作為標(biāo)準(zhǔn)對位移和幾何量進(jìn)行度量的儀器，LOS采用了自制的穩(wěn)頻激光作為激光光源，精度可達(dá)到n m量級。LOS可以在很遠(yuǎn)的距離達(dá)到很高的測試精度和解析度。

LOS系統(tǒng)應(yīng)用范圍廣，除了可用于長度的精密測量外，配上適當(dāng)?shù)母郊€可測量角度、直線度、平面度、振動距離及速度等等。

該公司同時(shí)提供基于CCD的幾何度量系統(tǒng)，使得測量更加靈活、快速，并保證精度。

主要特點(diǎn)：

3年內(nèi)激光波長精度不低于 0，02 ppm.
激光10年內(nèi)滿足測試要求
激光無需采用任何穩(wěn)頻措施（如加熱）

位移，速度、加速度測試

Standard LOS System configuration is designed to measure position， velocity and acceleration. A typical application is the calibration of positional accuracy of CNC machine tools. In this measurement the difference between the desired and actual position of the machine's moving part is evaluated. The method of measurement and evaluation corresponds to international standards (ISO 230-2， VDI/DGQ 2617，3441， NMTBA). The whole measurement process and printing of protocol is controlled by the computer programme and is fully automatic.

Software Compensation of Machine Tool Positional Errors

The measured positional errors can be transferred as correction data on line into the machine tool control system immediately after measurement. Considerable improvement of positional accuracy can thus be achieved in a minimum time. The producer delivers software modules which compensate for various control systems (SIEMENS， HEIDENHEIN， DYNAPATH， SELCA， YASNAC， FANUC， ACRAMATIC).

Further Applications

Positional accuracy of a co-ordinate measurement machine can be calibrated in a similar way (VDI 2617 standard). The LOS system is used also for the calibration of dimensional gauges. Laser systems cannot be replaced when precision measurement of long distances (up to 40 meters) is required.

線性度 Straightness 測量

閱讀: 1808

Errors in straightness of movement and in parallelity of axes can be measured by the LS 127ST set. The laser beam is split in the LS 127.1 differential beamsplitter into two parallel beams. After going through the optical wedge LS 127.2 the beams diverge at a small angle. The optical wedge functions as the straightness sensor. Reflector LS 127.3， formed by two inclined extremely precise plane mirrors， returns the beams back into the differential beamsplitter. The axis of the mirror reflector defines the straight line reference. This straightness measurement method is less sensitive to air turbulence disturbances than other methods. This straightness set also shows low sensitivity to possible inclinations of the straightness sensor during its movement at measurement.

The standard configuration for position measurement except the LS 20.1， LS 21.1， LS 70， LS 90.1， LS 90.3 is used for straightness measurement. The optical parts are fixed by the set of holders LS 51.
