What is the added value of lidar What is the added value of lidar for Arecibo Observatory?for Arecibo Observatory?
• The ISR is sensitive to ions• The lidar is sensitive to neutral atoms and
molecules, and one specific ion can be studied – Ca+
• Airglow can study specific height ranges, lidar can probe inside and outside those ranges.
• Under certain circumstances, lidar and radar, lidar and airglow, or all three can study the same parameters. This allows confirmation (or not) of measurements.

What is PhotonicsWhat is Photonics
Arecibo Observatory – 31 May 2013
• Photonics is the manipulation of light for technology development, science, and other applications.
• It is used in Communications, navigation, displays, remote sensing, biotech, medical devices, defense, security, energy, astronomy, space weather, computing, lighting, materials processing, environment, transportation, entertainment, computer-aided design…
What tools does Photonics What tools does Photonics Employ?Employ?
• Lasers of all types (from DVD players to welding)
• Fiber optics• Sensors, such as CCDs (a gift from
astronomy)• Electronics, to connect optical signals to
devices• Optical components (lenses, mirrors, etc.)
