2.2.Optical source adopts He-Ne laser emitter which owns better monochromaticity, high coherence, small divergence angle and good stability compared to other laser emitters, we also adopt the patent design of integrated laser emitter(patent no.: 00228952.0) which reduces heat distortion of laser tube and external mechanical vibration.
2.3.For laser emitter, except for traditional detection of output power value, we add the stability test of output power.
2.4.Smoothing processing technology is used to reduce the impact of power fluctuation to measurement.
2.5.Backward detector is added, the lower limit of measurement is extended to 0.1micron.
2.6.Detector array adopts unique scattered light detection around a sphere surface (DAS) (patent no.: 95223756.3), the large angle detectors are placed in a spherical surface to get accurate focus of the large angle scattered light.
3. Advanced data collection and processing technology
3.1.Using 8-channel simultaneous sampling to sample 16 bit ADC, the sampling frequency of frame data can reach
1 kHz.
3.2.Using 64-channel simultaneous sampling technology and sample & hold switch with ultralow leakage current, the full scale accuracy can reach 0.15%.
3.3.Offset function of electric background, it can help to get more accurate optical energy data.
3.4 Data collecting board adopts 32 bit CPU which is manufactured by famous ARM Company, it owns
high-efficiency signal processing capacity and low power consumption.
