2. Satellite imagery - Wikipedia

   en.wikipedia.org/wiki/Satellite_imagery

   In the commercial high-resolution satellite market, EROS is the smallest very high resolution satellite; it is very agile and thus enables very high performances. The satellites are deployed in a circular Sun-synchronous near polar orbit at an altitude of 510 km (± 40 km).

   The image of the sun's corona, assembled from high-resolution images taken by the orbiter's Extreme Ultraviolet Imager (EUI), shows active sunspot regions with protruding glowing plasma. Magnetic ...

4. Image resolution - Wikipedia

   en.wikipedia.org/wiki/Image_resolution

   The image would be a very low quality image (72ppi) if printed at about 28.5 inches wide, but a very good quality (300ppi) image if printed at about 7 inches wide. The number of photodiodes in a color digital camera image sensor is often a multiple of the number of pixels in the image it produces, because information from an array of color ...

   The images, taken on March 22, 2023, and released Wednesday, showcase different dynamic aspects of the sun, including the movements of its magnetic field and the glow of the ultrahot solar corona ...

6. Gigapixel image - Wikipedia

   en.wikipedia.org/wiki/Gigapixel_image

   Current technology for creating such very high-resolution images usually involves either making digital image mosaics of many high-resolution digital photographs or using a film negative as large as 12" × 9" (30 cm × 23 cm) up to 18" × 9" (46 cm × 23 cm), which is then scanned with a high-end large-format film scanner with at least 3000 dpi ...

7. Very Large Telescope - Wikipedia

   en.wikipedia.org/wiki/Very_Large_Telescope

   The ultraviolet and visual echelle spectrograph is a high-resolution ultraviolet and visible light echelle spectrograph. [55] VIMOS The visible multi-object spectrograph delivered visible images and spectra of up to 1,000 galaxies at a time in a 14 × 14 arcmin field of view.

8. Lucky imaging - Wikipedia

   en.wikipedia.org/wiki/Lucky_imaging

   The lucky imaging system averages the images taken during the excellent periods to produce a final image with much higher resolution than is possible with a conventional long-exposure AO camera. This technique is applicable to getting very high resolution images of only relatively small astronomical objects, up to 10 arcseconds in diameter, as ...

9. Astronomical optical interferometry - Wikipedia

   en.wikipedia.org/wiki/Astronomical_optical_inter...

   The use of this technique provided the first very high resolution images of nearby stars. In 1995 this technique was demonstrated on an array of separate optical telescopes as a Michelson Interferometer for the first time, allowing a further improvement in resolution, and allowing even higher resolution imaging of stellar surfaces.
