The COSETI Observatory

  • Continuous Wave, Monochromatic Laser Beacon Signals.

    • Incoherent Direct Detection Systems.
      • Use a monochromator or bandpass optical filter to reduce effect of background noise.
    • Coherent Optical Heterodyne Detection Systems.
      • Also reduces effect of background noise.
      • Only recommended for Professional OSETI systems because of difficulty in its implementation, tunability and its expense.
