Hyperspectral imaging (HSI) applications for biomedical imaging and dermatological applications have been recently under research interest. Medical HSI applications are non-invasive methods with high spatial and spectral resolution. HS imaging can be

VTT has previously developed Fabry-Pérot interferometer-based hyperspectral cameras which have been fixed focal length cameras. In some applications it would be beneficial to have zoom capability to first search the target and then zoom in to the ta

Introduction: The camera performance for space missions should be verified before flight. Exposure times with the expected fluxes should be planned, resulting signal-to-noise ratios (SNR) computed, and the overall image quality evaluated. This can be
