Dual Frequency Laser Measurement System

The dual-frequency laser measurement system is a modern high-precision measuring instrument featuring modular design, with a wide measurement range and high accuracy. It can be easily mounted on a measuring machine, replacing the original machine's coordinate system, and serves as a length reference for general measurements. Connected to a microcomputer, it can rapidly process measurement data, generate error curves, and provide a basis for the correction of precision machine tools and coordinate measuring machines.

However, due to the low prevalence of the dual-frequency laser measurement system, the measurement process differs from that of conventional autocollimators. It involves the addition of a spectrometer to the mirror, making adjustments time-consuming and labor-intensive.

One: Adjustment of Methods.

Adjust the beam parallel to the measured track.

(1) Position the mirror mount and the spectrometer mount on the track being tested. Place the spectrometer at the middle of the adjustable height range. Adjust the height, ensuring the laser head, mirror, and spectrometer are approximately at the same level.

(2) The left and right movement of the laser head is adjusted based on the offset of the light spot on the reflector in the Y-direction. On the mirror surface in the Y-direction, the light spot does not shift.

2. Adjust the mirrors and reflective mirrors to align their surfaces perpendicular to the laser beam.

(1) Adjust the mirror height to ensure that the laser beam emitted from the hole on the laser head is fully reflected back to the laser head (indicating light inside the hole illuminates).

(2) Position the spectrometer, cover the reflecting mirror, and adjust the height of the spectrometer so that all the light beams emitted from the hole on the laser head return after passing through the spectrometer (indicator light turns on).

That concludes our introduction to the dual-frequency laser. We hope it has been helpful to you.
