High stability and measurement accuracy are achieved with the newly developed optical system
Normal lasers are single wavelength, therefore due to interference, the pattern becomes patchy, as shown in the diagram on the right. This problem is rectified in the IB Series by utilising laser light with multiple wavelengths. Targets with a high level of difficulty can still be detected with a high degree of stability. Furthermore, by incorporating a high-sensitivity PD within the light receiving section data can be processed at high speeds, reducing the extraneous fluctuations to the absolute limit.
