Revision as of 10:59, 16 May 2022

Optical isolation tests using LED fibre in D27.

Aim: Investigate optimal material to use to optically isolate unpainted sheets and whether single layers of material provide sufficient isolation.

Notes

  • DDC232 settings: 170us integration time and measured 10000 samples per run.
  • Signal Generator settings: 0 ps delay, 500 kHz, 300 ns width, 5 ns leading edge and trailing edge, 6V high, 0V low.
  • Fibres used: 25 and 29 (25 used for single injection tests).
  • Sheets used: 84, 82, 81, 80, 79, 78, 77, 76, 75
  • Materials tested: none, white paper (0.01 mm thick), black card (0.02 mm thick), mylar foil (0.0012 mm thick). Materials cut into 10 cm x 10 cm layers and placed in-between sheets.
