Snapshot multispectral endomicroscopy
Optics Letters, 2020Multispectral endomicroscopy provides tissue functional information in addition to structural information for accurate disease diagnosis. In this Letter, we propose a snapshot multispectral endomicroscope that employs a fiber bundle to deliver an in-body tissue spatial–spectral datastream to an external compressive spectral imager. Equipped with an end-

The Multispectral Dermoscope has been used for imaging skin lesions. Illumination at three different spectral regions and subsequent image processing can provide information on the localization of melanin, hemoglobin and scattering structures in the skin.

An experience in multispectral mosaicing
SPIE Proceedings, 2005The acquisition of large or high-resolution multispectral images may require that different parts of the scene be acquired separately and then be mosaicked to obtain the whole image. While the problem of stitching together parts of an image to form a consistent whole has been studied rather extensively for traditional images, in this case view angles ...

Large-aperture linear diffractive axicons are optical devices providing achromatic nondiffracting beams with an extended depth of focus when illuminated by white light sources. Annular apertures introduce chromatic foci separation, making chromatic imaging possible despite important radiometric losses.

Multispectral image compression
Proceedings. Fourteenth International Conference on Pattern Recognition (Cat. No.98EX170), 2002Image compression has been one of the mainstream research topics in image processing. The research usually focuses on compressing images that are visible to humans. Images are usually gray-level images or RGB color images. Advances in technology enable one to make the detailed processing of spectral color features in the images.

The shortcomings of the conventional three-channel imaging are rooted in metamerism problems. To avoid these problems multispectral imaging is introduced as an complementary approach. This imaging technology uses the complete spectral information of the original image, and, hence, avoids the problems due to metamerism.

In this paper, we investigate the problem of visual odometry for ground vehicles based on the simultaneous utilization of multispectral cameras. It encompasses a stereo rig composed of an optical (visible) and thermal sensors. The novelty resides in the localization of the cameras as a stereo setup rather than two monocular cameras of different ...

Multispectral microbolometers for the midinfrared
Optics Letters, 2010The spectral responsivity and the dynamic behavior of microbolometers with an integrated absorbing metamaterial are investigated. Wavelength tailoring and tuning in different microbolometers are achieved by varying the lateral extension of the absorber elements.
