Abstract

Laser sensing and imaging now have growing importance in various fields ranging but not limited to atmospheric chemistry, industrial process surveillance, agriculture, and medical diagnostics. More and more special conferences and symposia have appeared, devoted to certain aspects of sensing and imaging. LIDAR is popularly used as a technology to make high-resolution maps, with applications in archaeology, geography, geology, geomorphology, seismology, forestry, remote sensing, atmospheric physics, etc. Novel laser sources, spectroscopic approaches and imaging techniques play an increasing role as they enable noncontact sensing without or with only minimal sample pretreatment and/or sample preparation. Furthermore, the appearance of mid-infrared fiber laser sources is changing the application landscape of such techniques. In this special section, we present a collection of selective papers that represents to a certain extent the recent advances in laser sensing and imaging and the related technologies.

Summary

Introduction

Laser sensing and imaging have growing importance in various fields ranging but not limited to atmospheric chemistry, industrial process surveillance, agriculture, and medical diagnostics. We present a collection of selective papers that represents to a certain extent the recent advances in laser sensing and imaging and the related technologies. R. Zhang et al, summarizes the various optical detection methods, including nondispersive infrared gas analyzer, ultraviolet differential optical absorption spectroscopy, Fourier transform infrared spectroscopy, and tunable diode laser absorption spectroscopy, for the monitoring of harmful gases in animal housing.
