Abstract

The HySpex ODIN-1024 is an airborne VNIR-SWIR hyperspectral imaging system which advances the state of the art with respect to both performance and system functionality. HySpex ODIN-1024 is designed as a single instrument for both VNIR (0.4 to 1 μm wavelength) and SWIR (1 to 2.5 μm) rather than being a combination of two separate instruments. With the common fore-optics of the single instrument, a more accurate and stable co-registration is achieved across the full spectral range compared to having two individual instruments. For SWIR the across-the-track resolution is 1024 pixels, while for VNIR the user of the instrument can choose a resolution of either 1024 or 2048 pixels. In addition to high spatial resolution, the optical design enables low smile- and keystone distortion and high sensitivity obtained through low F-numbers of F1.64 for VNIR and F2.0 for SWIR. The camera utilizes state of the art scientific CMOS (VNIR) and MCT (SWIR) sensors with low readout noise, high speed and spatial resolution. The system has an onboard-calibration subsystem to monitor the stability of the instrument during variations in environmental conditions. It features an integrated real-time processing functionality, enabling real-time detection, classification, and georeferencing. We present an overview of the performance of the instrument and results from airborne data acquisitions.
