Compact camera for multispectral and conventional imaging based on patterned filters
(2014)
A multispectral camera concept is presented. The concept is based on using a patterned filter in the focal plane, combined with scanning of the field of view. The filter layout has stripes of different bandpass filters ...
Characterization of a compact 6-band multifunctional camera based on patterned spectral filters in the focal plane
(2014)
In some applications of multi- or hyperspectral imaging, it is important to have a compact sensor. The most compact spectral imaging sensors are based on spectral filtering in the focal plane. For hyperspectral imaging, ...
Compact multispectral multi-camera imaging system for small UAVs
(2016)
Cameras with filters in the focal plane provide the most compact solution for multispectral imaging. A small UAV can carry multiple such cameras, providing large area coverage rate at high spatial resolution. We investigate ...
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 ...
Simplified measurement of point spread functions of hyperspectral cameras for assessment of spatial coregistration
(2019-05-14)
In multi- and hyperspectral imaging, spatial coregistration of the point spread functions (PSFs) of all bands within each pixel is critical for the integrity of measured spectra. There is a need to define a standardized ...
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 ...
