A method for improving resistance of display of OCT equipment to electromagnetic field interference radiated by radio frequency

[0015] In the following, the present invention will be further described in conjunction with the embodiments.

[0016] A method to improve the resistance of the OCT equipment display to radio frequency radiation electromagnetic field interference. First, use a copper sheet or a copper connection tape to connect the shielding cover originally installed on the display control board to the metal plate, so that the shielding cover is affected by external radio frequency interference. The potential is connected to the earth through the metal plate; secondly, the opening on the original shielding cover is blocked with copper to prevent the radiated electromagnetic field from directly entering the shielding cover and causing breakdown of the sensitive circuit; thirdly, the longer length of the control board The wire is connected in series with a magnetic ring to reduce the coupling interference of 28V/m radio frequency interference to the wire. This is because under 28V/m radio frequency interference, it is easy to couple the interference to the wire, thereby affecting the normal display of the display.

[0017] The parts not involved in the present invention are the same as the prior art or can be implemented by the prior art.
