Abstract The paper describes practical application of pulsed microchip laser generating at 1535-nm wavelength to a rangefinder. complete prototype rangefinder was built and investigated in real environmental conditions. measured performance the device is discussed. To build reasonable price shape number basic considerations had be done. These include mechanical optical design opto-mechanical construction
Widespread availability of drones is associated with many new fascinating possibilities, which were reserved in the past for few. Unfortunately, this technology also has negative consequences related to illegal activities (surveillance, smuggling). For reason, particularly sensitive areas should be equipped sensors capable detecting presence even miniature from as far away possible. A few techniques currently exist field; however, all have significant drawbacks. This study addresses a novel...
LIDAR system for real-time standoff detection of bio-agents is presented and preliminary experimental results are discussed. The approach based on two independent physical phenomena: (1) laser induced fluorescence (LIF), (2) depolarization resulting from elastic scattering non-spherical particles. device includes three sources, receiving telescopes, component spectral signature analyzing spectrograph. It was designed to provide the stand-off capability at ranges 200 m up several kilometers....
The article presents methods of long range distance measurements using pulsed lasers and the Time Flight principle. Various algorithms laser with digital acquisition echo pulses (acquisition a signal's full waveform) are presented. main focus work is concentrated on method developed by authors. With this method, during laboratory trials, total measurement error one centimeter was achieved 905 nm diode pulse width 39 ns. maximum such high precision limited only signal to noise ratio, duration...

Measurement of vehicles speed by means displacement measurement with "time flight" lidar requires gathering accurate information about distance to the vehicle in a set time interval. As any pulsed laser lidar, its maximum range is limited available incoming signal noise ratio. That ratio determines not only range, but also accuracy measurement. For fast and precise measurements their should bee measured centimeter accuracy. However that demand hard reach on long distances poor quality echo...
LIDAR [1] system for real-time standoff detection of bio-agents is presented and preliminary experimental results are discussed. The approach based on two independent physical phenomena: - laser induced fluorescence [2], depolarization resulting from elastic scattering non-spherical particles [3].

Lidar technology in terms of real-time stand-off detection both biological and chemical airborne materials is discussed this paper. If faced to optical electromagnetic radiation, types species present different fingerprint features. For reason lidar architectures for also differ significantly. Biological based on UV-laser induced fluorescence depolarization phenomena (LIF-DEPOL-LIDAR), while can be performed the regime LWIR absorption spectra analysis (DIAL - Differential Absorption Lidar)....
Abstract We report methodology of three-dimensional laser beam shaping. The analytical and numerical analysis is presented. A strategy for designing optical system involves the controlled application aberrations which realized by specific aspheric lens goal to obtain desired power density distribution in space, optimal selected application. proposed method discussed with regard design transmitter shooting simulator, however developed can be used a number other light shaping applications
The article presents results of research on the influence changes in parameters digitally recorded echo signals uncertainty pulsed Time-of-Flight (p-ToF) laser distance measurements. main objective study was to evaluate calculation method developed by authors.
