DFM Engineering has provided many Electro-Optical-Mechanical Systems™ (EOMS™) in scanners
used for Light Detection And Ranging (LIDAR) remote sensing applications.
Typically these scanners are an Alt-Az Coude' form of a beam director using two flat mirrors.
The major difference between a LIDAR scanner and a beam
director is the scanner has a lower angular resolution and a higher speed.
The optics may be of lower optical figure because of the longer wavelengths often used.
The scanners may also incorporate additional EOMS™ components such as collimating
optics, zoom lenses, focus motion, fiber feed, etc.
DFM Engineering has designed and manufactured over 30 EOMS™ incorporating these features that were
used to measure the atmospheric turbulence.
Three were near a helicopter landing ship where stabilization of the scanner to correct for a ship's
roll, pith, and yaw has also been provided.
