Full characterization of spatial coregistration errors and spatial resolution in spectral imagers
(2018)
For multi- and hyperspectral imagers, the integrity of the spectral information depends critically on the spatial coregistration between bands. There is at present no commonly accepted way to fully specify coregistration ...
Thermal infrared reference sources fabricated from low-cost components and materials
(2018)
Mass markets, including mobile phones and automotive sensors, drive rapid developments of imaging technologies
toward high performance, low cost sensors, even for the thermal infrared. Good infrared calibration blackbody ...
Measurement of point spread function for characterization of coregistration and resolution: Comparison of two commercial hyperspectral cameras
(2018)
For spectral cameras, the spatial resolution and coregistration of bands are important performance characteristics. The paper discusses how these can be quantified in a way that is relevant for the spectroscopic processing ...
Combined range ambiguity resolution and noise reduction in lidar signal processing
(2018)
When the interval between transmitted pulses is shorter than the time of flight, it is not straightforward for a lidar to determine the distance uniquely. We present a method that uses varying pulse intervals, constructs ...
