If y is the max radial size of the image then θ is the field of view of the lens. While the image created by a lens is continuous, it can be modeled as a set of discrete field points, each representing a point on the object. The quality of the image is limited by the aberrations in the lens and the diffraction created by the finite aperture stop.
ASTER image draped over terrain model of Mount Etna. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is a Japanese remote sensing instrument onboard the Terra satellite launched by NASA in 1999. It has been collecting data since February 2000. ASTER image of Rub' al Khali (Arabia's Empty Quarter)
The degree of spreading (blurring) in the image of a point object for an imaging system is a measure of the quality of the imaging system. In non-coherent imaging systems, such as fluorescent microscopes, telescopes or optical microscopes, the image formation process is linear in the image intensity and described by a linear system theory. This ...
Expedition 8 Commander and Science Officer Michael Foale conducts an inspection of the Microgravity Science Glovebox. ESA astronaut Thomas Reiter, STS-116 mission specialist, works with the Passive Observatories for Experimental Microbial Systems in Micro-G (POEMS) payload in the Minus Eighty Degree Laboratory Freezer for ISS (MELFI) inside the Destiny laboratory.
Space Automated Bioproduct Lab (SABL): can be used for experiments in the life, physical and material sciences with a focus on supporting research of biological systems and processes. [21] Microorganisms, small organisms, animal cells, tissue cultures, and small plants are studied in this lab.
Satellite formation flying is the coordination of multiple satellites to accomplish the objective of one larger, usually more expensive, satellite. [1] Coordinating smaller satellites has many benefits over single satellites including simpler designs, faster build times, cheaper replacement creating higher redundancy, unprecedented high resolution, and the ability to view research targets from ...
Multispectral image of Bek crater and its ray system on the surface of Mercury, acquired by MESSENGER, combining images at wavelengths of 996, 748, 433 nm. The bright yellow patches in other parts of the image are hollows. Multispectral imaging captures image data within specific wavelength ranges across the electromagnetic spectrum.
The US National Lab conducts research in life sciences, physical sciences, technology development and remote sensing for a wide variety of academic, government and commercial users. [3] Researchers choose to conduct experiments in space because of the unique effects that microgravity, or weightlessness, has on physical and biological phenomena ...
