Abstract
Abstract. A new Fabry-Perot interferometer (FPI) based light-weight spectrometric camera provides new possibilities for environmental remote sensing applications. The sensor collects spectral data cubes with adjustable spectral properties in a rectangular image format, and so stereoscopic data can be obtained by gathering images in block structures with overlapping images. The FPI camera thus enables stereoscopic, spectrometric remote sensing applications with light-weight, low-cost airborne imaging systems. Our objective is to investigate the processing and use of this new imaging technology in a water quality mapping. We carried out imaging campaigns over a small lake in summer and autumn 2012 using a light-weight unmanned airborne vehicle (UAV) and a small manned airborne vehicle (MAV). We present the preliminary results of these campaigns.
Highlights
One of the recent innovations in the field of airborne remote sensing is the Fabry-Perot interferometer (FPI) based lightweight spectrometric camera developed by the VTT Technical Research Centre Finland (VTT) (Mäkynen et al, 2011; Saari et al, 2011)
We carried out imaging campaigns with the FPI spectral camera using manned airborne vehicle (MAV) and unmanned airborne vehicle (UAV) platforms in summer and autumn 2012
The FPI spectral camera can operate in the wavelength range of 400-1000 nm, with a full width at half maximum (FWHM) of 10-40 nm; the number of bands and their characteristics can be selected flexibly according to the requirements of the application
Summary
One of the recent innovations in the field of airborne remote sensing is the Fabry-Perot interferometer (FPI) based lightweight spectrometric camera developed by the VTT Technical Research Centre Finland (VTT) (Mäkynen et al, 2011; Saari et al, 2011) It provides spectral data cubes with a rectangular image format, giving a possibility for production of spectral 3D information when images are collected in image blocks with stereoscopic overlaps. We carried out imaging campaigns with the FPI spectral camera using MAV and UAV platforms in summer and autumn 2012 In all of these campaigns, imaging conditions were extremely challenging, which provided highly variable data quality; this was characteristic for the summer 2012 in Finland during the entire season for vegetation remote sensing.
