Which EMC (electromagnetic compatibility) devices are helpful for the design and modification of skin analyzers?

EMC (Electromagnetic Compatibility) of the skin analyzer must ensure image quality. Multiple LED light sources should be illuminated in a time-sharing manner, with each channel driven by a constant current to avoid brightness fluctuations and mutual interference. The power supply for the camera module must be exceptionally clean; an independent LDO power supply can be used, with impedance control and shielding applied to its clock and data lines. High-quality cables should be used for the interface between the image acquisition card (e.g., independent device) and the host (computer) (e.g., USB 3.0, Camera Link), and ESD protection should be added to the interface (e.g., ESDULC5V0D9B for high-speed interfaces). The device casing should be grounded, and the internal optical and circuit components may be separated by a partition.
