Sentences with phrase «focal plane»
The phrase "focal plane" refers to the specific area where an image is sharply focused when using a camera or microscope. It is the plane in which objects appear clearest and in focus. Full definition

In addition to transitioning to a separate organization, we have two new high frequency instruments coming online this winter — MUSTANG2, a 70 - 105 GHz, 210 element bolometer array, and ARGUS, a 75 - 116 GHz, 16 element focal plane array.
In November of last year, a collaborative effort involving representatives of the Academia Sinica Institute of Astronomy and Astrophysics, University of Wisconsin, NRAO, and the Green Bank Observatory gathered to review designs for a proposed focal plane array for the GBT.
Argus is a new 16 - element 75 - 116 GHz focal plane array instrument installed on the GBT.
The current WFIRST version produces images covering a single detector in the Wide Field Imager (WFI) field of view; a future enhancement will be able to generate the full WFI focal plane simultaneously.
INX - 1:: GFP appears to lie in a different focal plane from UNC - 7 in the nerve cords (which may relate to expression in highly - coupled muscle arms that extend to the nerve cords).
This sequencing of photographs and shifting of focal planes allows me the luxury of guiding the viewer across the photograph, directing their eye; an effect which could not be achieved through a single image.
But more immediately, Wilson gives form to our increasingly fraught sense of having to change cognitive frames or focal planes countless times just to get through an ordinary 21st century day.
Television has made multiple focus acceptable; as a result we can see many different focal planes all at once.
Therefore, wings were imaged at 20x as mosaics under multiple focal planes, so that setae on both wing surfaces and all nuclei could be detected.
The fourth mirror allows for exquisite control of the streams of photons so that they fall almost perpendicular to the instrument's focal plane, ensuring «very good image quality,» Cui says.
