Quality Control
- Optical component
For the laser in the laser emission module, the parameters such as wavelength accuracy and output power stability need to be strictly tested. For example, the deviation of the wavelength may affect the accurate reception and resolution of the light reflected by the liDAR on the target object, and the wavelength deviation is generally required to be controlled within a very small range, such as ±5nm.
The quality of the optical lens is also crucial. The curvature accuracy of the lens, the surface flatness and the transmittance of different wavelengths of laser light are all carefully tested. Any small flaw, such as a scratch or uneven curvature on the lens surface, can cause the laser to scatter or focus inaccurately, thus affecting the detection accuracy of the liDAR. The transmittance is generally required to reach more than 90% in a specific band.
- Electronic components
The chip on the circuit board is the "brain" of the lidar, and when conducting quality control, it is necessary to ensure that the performance of the chip meets the design requirements. For example, to test whether its data processing speed can meet the needs of liDAR to acquire and process large amounts of point cloud data in real time. At the same time, it is also necessary to check the stability of the chip in different temperature environments, because the lidar may generate heat during the working process, and the chip performance must be stable within a certain temperature range (such as -40 ℃ -85 ℃).
The parameter accuracy of capacitors, resistors and other discrete components can not be ignored. The deviation range between the nominal value and the actual value of these components should be controlled within a certain limit, such as the resistance value deviation of the resistance does not exceed ±1%, to ensure the normal operation of the circuit and the accuracy of signal transmission.
