Spaceborne scanning lidar system (SSLS)

SPIE Proceedings, 2005
The Spaceborne Scanning Lidar System (SSLS) system is a space qualified scanning lidar system developed by MDA, Space Missions (MD Robotics) and Optech. It is scheduled to be launched in 2005 as part of a one year on-orbit demonstration of space technologies associated with spacecraft autonomous rendezvous and proximity operations.

Urban air pollution monitoring using scanning Lidar

Environmental Pollution, 2020
We have developed a scanning Lidar system in this work to detect urban air pollution changes in real time and locate the sources of urban air pollution. We first proposed an algorithm to retrieve atmospheric extinction coefficients, which we used to create Lidar maps.

Doppler spectral scanning differential absorption lidar

SPIE Proceedings, 2002
Preliminary experiments toward the implementation of Doppler spectral scanning differential absorption lidar (DSS DIAL) are described. In separate tests, CO2 laser pulses were reflected from either a ground-based retroreflector (36-km round-trip distance) or a retroreflector on the GEOS-3 satellite (approximately 2000-km round-trip distance).

Rapid 2-axis scanning lidar prototype

SPIE Proceedings, 2016
The rapid 2-axis scanning lidar prototype was developed to demonstrate high-precision single-pixel linear-mode lidar performance. The lidar system is a combined integration of components from various commercial products allowing for future customization and performance enhancements. The intent of the prototype scanner is to demonstrate current stateof-

Differential method for processing scanning lidar data

Applied Optics, 2015
The significant deficiency of the classic multiangle data-processing technique is that the accuracy of the lidar-data inversion strongly depends on whether the assumption of the horizontal stratification of the searched atmosphere is valid. The aggravating factor is that no reliable methodology exists that would allow establishment of whether the above

Random impulsive scan for lidar sampling

2012 19th IEEE International Conference on Image Processing, 2012
In this paper, we address the problem of sampling the LIDAR range map. The significance of this problem is based upon the fact that large datasets generated by sampling inefficiently impose storage, processing and transmission limitations. Current compression approaches addressing these issues rely on collecting large amounts of data to analyze and ...

Early forest-fire detection using scanning polarization lidar

Applied Optics, 2020
As forest terrain is complex, containing leaves and other obstacles, it is difficult to distinguish the signal of forest-fire smoke when using single-channel lidar. To address this difficulty, a scanning micropulse polarization lidar system is developed, and a new method to detect forest fires is proposed in this study.

Scanning LiDAR for airfield damage assessment

Signal Processing, Sensor/Information Fusion, and Target Recognition XXVII, 2018
The ability to rapidly assess damage to military infrastructure after an attack is the object of ongoing research. In the case of runways, sensor systems capable of detecting and locating craters, spall, unexploded ordinance, and debris are necessary to quickly and efficiently deploy assets to restore a minimum airfield operating surface.

Eye-safe compact scanning LIDAR technology

Optics and Lasers in Engineering, 2007
Abstract A 1.5- μ m eye-safe, 3-D scanning, and compact Mie LIght Detection and Ranging (LIDAR) is presented. The transmitter of the LIDAR is based on a KTA optical parameter oscillator (OPO) resonator. For detecting return signals, an InGaAs APD is used. The all solid-state OPO laser transmitter has the feature of small volume and lightweight,

Non-scanning imaging laser Lidar equation

2012 International Conference on Optoelectronics and Microelectronics, 2012
Imaging laser Lidar process is analyzed in this paper, and a large FOV non-scanning imaging laser Lidar equation suitable for received energy calculation is proposed. Every parameters in this equation have distinct physical meaning. These parameters can be obtained by experiments, without experience estimate, or by exist literature material.
