Multispectral imaging measures light emission and is often used in detecting or tracking military targets. In 2003, researchers at the United States Army Research Laboratory and the Federal Laboratory Collaborative Technology Alliance reported a dual band multispectral imaging focal plane array (FPA). This FPA allowed researchers to look at two infrared (IR) planes at the same time. Because mid-wave infrared (MWIR) and long wave infrared (LWIR) technologies measure r… WebApr 13, 2024 · a direct infrared image of the hip 99770 star system captured with w. m. keck observatory’s nirc2 instrument paired with the keck ii telescope adaptive optics system. the bright host star is masked, as marked by the yellow star icon. the dashed circle shows the size of jupiter’s orbit around the sun for scale. the white arrow points to the extrasolar …
