Embodiment Construction
[0015] The present invention will be further described below in conjunction with embodiment.
[0016] A method for improving the anti-radiofrequency electromagnetic field interference of the OCT equipment display. First, the shielding cover originally installed on the display control board is connected to the metal plate with a copper sheet or a copper connection belt, so that the shielding cover is subjected to external radio frequency interference. The potential is connected to the ground through the metal plate; secondly, the opening on the original shielding cover is blocked with a copper sheet to prevent the radiated electromagnetic field from directly entering the shielding cover and causing breakdown of the sensitive circuit; The wires are connected in series with magnetic rings to reduce the coupling interference caused by 28V / m radio frequency interference on the wires. This is because under 28V / m radio frequency interference, it is easy to couple the interference to ...
