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

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
