ALISEO ON MIOSAT: AN AEROSPACE IMAGING INTERFEROMETER FOR EARTH OBSERVATION Alessandro Barducci, Francesco Castagnoli, Guido Castellini, Donatella Guzzi, Paolo Marcoionni, Ivan Pippi CNR – IFAC Via Madonna del Piano 10, 50019 Sesto Fiorentino, ITALY Tel.: +39 0555226301, Fax: +39 0555226348, E-mail: I.Pippi@ifac.cnr.it 1. INTRODUCTION In this paper we describe a new instrument named ALISEO (Aerospace Leap-frog Imaging Stationary Interferometer for Earth Observation), which belongs to the class of the “stationary interferometers”. ALISEO has been selected as the main payload for a novel Italian Space Agency (ASI) optical mission based on a micro-satellite (MIOSat) with steering capability. The mission is constituted by a micro-satellite equipped with advanced payloads, among which there are an extensible telescope, a high-resolution panchromatic camera, a Mach-Zehnder MEMS punctual interferometer, and ALISEO. MIOSat is expected to provide the scientific community with the technological demonstration of this new remote sensing technology. A valuable advantage of imaging interferometers is their ability to change the sampled spectral range and their resolving power by simply adjusting the sensor sampling step and the instrument Field-Of-View (FOV) [1], [2]. An additional advantage is avoiding the adoption of any input slit, which strongly reduces the radiant power admitted in dispersive spectrometers. Critical points are associated with the heavy data preprocessing necessary for compensating the instrument response and possible acquisition artefacts [3]. Moreover, due to the nature of the acquired interferogram it is crucial adopting detectors with high digitalisation accuracy [4] (Sellar, 2003) . 2. ALISEO INSTRUMENT CONCEPT ALISEO operates in the common-path Sagnac triangular configuration, and it does not employ any moving part to generate phase delay between the two allowed ray paths. The sensor acquires target images modulated by a pattern of autocorrelation functions of the energy coming from each scene pixel, a fringe pattern that is fixed with respect to the instrument’s field of view. The complete interferogram of each target location is retrieved introducing relative source-observer motion, which allows any image pixels to be observed under different phase delays. In this paper some laboratory measurements performed with an ALISEO prototype will be presented and discussed. A set of measurements have been carried out using both standard reflectance tiles and samples of different volcanic rocks. An algorithm for raw data pre-processing aimed at retrieving the at-sensor radiance spectrum, including exploiting the issues of dark signal subtraction, spectral instrument response compensation, effects of vignetting, and Fourier back-transform algorithm will be discussed. Finally, reflectance spectra for several samples utilised during laboratory measurements will be shown. 3. REFERENCES [1] W. B. Harnisch, E. Hartman, W. Holota, M. Melf, W. Posselt, M. Rost, M.
