Lidar Structure
Multiwavelength Lidar System ConceptEmmision at 355, 532 and 1064 nmReception:
• 355 nm co and cross-polarized• 532 nm co and cross-polarized• 1064 nm• 384 nm N2 Channel• 408 nm H2O Channel• 607 nm N2 Channel
Aluminum structure to hold the whole system and protect the components
Iron structure to reduce thermal effects and keep the critical optical elements aligned

Lidar Stucture
Multiwavelength Lidar System ConceptEmmision at 355, 532 and 1064 nmReception:• 355 nm co and cross-polarized• 532 nm co and cross-polarized• 1064 nm• 384 nm N2 Channel• 408 nm H2O Channel• 607 nm N2 Channel
Aluminum structure to hold the whole system and protect the components
Iron structure to reduce thermal effects and keep the critical optical elements aligned
Lidar Structure
Emmision by fused silica prism total internal reflection
Alignment precision reach 1.67 mrad per turn (1/20th reduction)
To reduce undesirable telescope shadowing during the alignment a torsion resistant cable transmit the torque to the alignment screws
The alignment structure is attached to the iron frame then it is mechanically decoupled from the telescope
Lidar Structure
• Spectroscopic Box air coupled to the telescope.
• All UV channels H10721-110• All Vis channels H10721-20• LICEL 3mm APD

Software Retrieval and Analysis
Software Retrieval and Analysis
• Each Station links to the NIES FTP server for backup.
• FTP server is then downloaded to Prof. Sugimoto SFTP server.
• Data analysis is done at NIES• Data analysis will be done at
CITEDEF• Comodoro experience shows
that near real time analysis is possible

Remote Assistance• Based on Team Viewer. No VPN.
Need to be improved.• Innovared may be studied as a
possible solution
Online Communication• Crisis software already implemented for
SABER.Net already presented at the National Risk Management System, MINCyT
• Comunication channel is going to migrate to Crisis Software
