Electromagnetic Field Sensor

  1. Jul 13, 2016 #1
    Which is better and how to do it?

    Make a spaceship an electromganetic field and go through a sensor so at the end of the race it must pass between the sensors to win, and what sensor would you need for very close width. Saying the spaceship is 20ft wide and both sides must be between the 80ft wide sensor.

    Or would you make an 80ft wide electromagnetic field and have the 20ft wide spaceship get sensed?

    I'm not sure I understand the context or the question, but why not just use the proven technology of photosensors? That's used in drag races at the finish line, I believe...
