What is ultraviolet spectrograph?
The Ultraviolet Imaging Spectrograph (known to the science team as UVIS) was a box of four telescopes that could see ultraviolet light, which is invisible to the human eye.
What is the ultraviolet camera?
UV cameras are a style of video camera that have been optimized for capturing light from the ultraviolet spectrum. This is accomplished by using a UV-pass filter, which will only allow light below the visible spectrum (wavelengths less than 400 nm). Regular CCD sensors are capable of recording UV light.
Who created the ultraviolet camera spectrograph?
Dr. Carruthers made the first detection of molecular hydrogen in space, in 1970, using a sounding rocket. He developed a rocket instrument that obtained a UV image of Comet Halley, and an instrument with two cameras, with different far-UV wavelength sensitivities, used on the STS-39 space shuttle mission in 1991.
What Uvis is and what it does?
UVIS is a remote sensing instrument (think sight–from very far away) that captures UV light reflected off objects, like Saturn’s rings or clouds, and turns it into images that it sends back to scientists on Earth.
What tools are used in ultraviolet light?
The Cosmic Origins Spectrograph (COS) breaks ultraviolet light into components that can be studied in detail as a one-dimensional spectrum. Its Space Telescope Imaging Spectrograph (STIS) provides data about a celestial object’s temperature, chemical composition, density and motion as a two-dimensional spectrum.
What means ultraviolet?
Definition of ultraviolet 1 : situated beyond the visible spectrum at its violet end —used of radiation having a wavelength shorter than wavelengths of visible light and longer than those of X-rays. 2 : relating to, producing, or employing ultraviolet radiation.
How does UV lens work?
UV lens filters are made from glass that passes all or nearly all light on the visible spectrum, but blocks UV light at a specific wavelength, typically below 400 nm. You can find various filters according to how much UV light they absorb by percentage and nanometers.
Who invented the space camera?
George Robert Carruthers
George Robert Carruthers (October 1, 1939 – December 26, 2020) was an African American inventor, physicist, engineer and space scientist. Carruthers perfected a compact and very powerful ultraviolet camera/spectrograph for NASA to use when it launched Apollo 16 in 1972.
When were UV cameras invented?
Scientist George Carruthers created inventions, such as the ultraviolet camera, or spectrograph, which was used by NASA in the 1972 Apollo 16 flight, revealing the mysteries of space and the Earth’s atmosphere.
How is UV light measured?
For radiation in the UV region of the spectrum, wavelengths are measured in nanometers (nm), where 1 nm = one millionth of a millimeter.
How is UV level measured?
A computer model uses the ozone forecast and the incident angle of sunlight at each point to calculate the strength of UV radiation at ground level. Sunlight angle is determined by latitude, day of year, and time of day (solar noon).
What is a far ultraviolet electrographic camera?
Working for the Naval Research Laboratory, Carruthers had three years earlier received a patent for a Far Ultraviolet Electrographic Camera, which obtained images of electromagnetic radiation in short wavelengths.
What is the ultraviolet Imaging Spectrograph?
The Ultraviolet Imaging Spectrograph (known to the science team as UVIS) was a box of four telescopes that could see ultraviolet light, which is invisible to the human eye. On Earth, ultraviolet light causes sunburns, but with a space-based spectrograph, ultraviolet light shows researchers what no other type of light can show.
Who is the principal investigator for the lunar surface ultraviolet camera?
George Carruthers principal investigator for the Lunar Surface Ultraviolet Camera, discusses the instrument with Apollo 16 Commander John Young, right. Carruthers is employed by the Naval Research Lab in Washington, D.C. From left are Lunar Module Pilot Charles Duke and Rocco Petrone, Apollo Program Director.
What is ultraviolet light?
Ultraviolet light is the electromagnetic radiation between visible light and x-rays. George Carruthers first major contribution to science was to lead the team that invented the far ultraviolet camera spectrograph.
