What is an Atomic line filter ? Mention it's uses ?

Hi,
An atomic line filter (ALF) is an advanced optical band-pass filter used in the physical sciences for filtering electromagnetic radiation with precision, accuracy, and minimal signal strength loss. Atomic line filters work via the absorption or resonance lines of atomic vapors and so may also be designated an atomic resonance filter (ARF)

Atomic line filters are most often used in LIDAR and other exercises in laser tracking and detection, for their ability to filter daylight and effectively discern weak, narrowband signals; however, they may be used for filtering out the earth’s thermal background,[33] measuring the efficiencies of antibiotics[34] and general filtering applications.

Laser tracking and communication
Without an atomic line filter, laser tracking and communication may be difficult. Usually, intensified charge-coupled device cameras must be used in conjunction with simple dielectric optical filters (e.g. interference filters) to detect laser emissions at a distance. Intensified CCDs are inefficient and necessitate the use of a pulsed laser transmission within the visible spectrum. With the superior filtering system of an ALF, a non-intensified CCD may be used with a continuous wave laser more efficiently. “[Atomic line filters] with passbands of about 0.001 nm have been developed to improve the background rejection of conventionally filtered laser receivers”.The total energy consumption of the latter system is “30 to 35 times less” than that of the former,so space-based, underwater and agile laser communications with ALFs have been proposed and developed.

LIDAR
LIDAR comprises firing lasers at relevant portions of the atmosphere where light is backscattered. By analyzing the reflected laser beam for Doppler shifts, wind speeds and wind directions in the target region may be calculated. The thermal structure, diurnal/semi-diurnal tides, and seasonal variations in the mesopause region may thus be studied. This is a valuable faculty for meteorologists and climatologists, as these properties can be significant.
However, without the ability to effectively track weak laser signals, collection of atmospheric data would be relegated to times of day where the sun's electromagnetic emissions did not drown out the laser's signal. The addition of an atomic line filter to the LIDAR equipment effectively filters interference to the laser's signal to the point where LIDAR data can be collected at any time of the day.[5] For the past decade, Faraday filters have been used to do this. Consequently, scientists know significantly more today about the Earth’s middle atmosphere than they did before the advent of the FADOF.
