fluorescent screen การใช้

• They used a fluorescent screen to measure the trajectories of the particles.
• Modern image intensifiers no longer use a separate fluorescent screen.
• The diffraction spots are generated by acceleration of elastically scattered electrons onto a hemispherical fluorescent screen.
• He was the first person to use a fluorescent screen to enhance X-rays for medical purposes.
• Square wave signals were detected on the fluorescent screen of a fluoroscope to create the image.
• In another attempt, the Edison fluorescent screen was placed on a photographic plate and the patient's hand on the screen.
• The diffraction spots are generated by acceleration of elastically scattered electrons onto a hemispherical fluorescent screen, a retarding field analyzer.
• The resulting diffraction pattern is then observed on a fluorescent screen, recorded on photographic film, on imaging plates or using a CCD camera.
• He was known for research that used electron microscopes, which project electron beams through thin biological specimens to form images on a fluorescent screen and on film.
• In a dark room, Chrissy sits on a hard-back chair and concentrates on a fluorescent screen before him while lifting his right foot in slow, precise movements.
• "Paper is very transparent; behind a bound book of about 1, 000 pages I saw the fluorescent screen light up brightly, the printer's ink offering scarcely a noticeable hindrance.
• A fluorescent screen was used to ultimately determine the exact location of the source, but the team had to wait for cloud cover to reduce moonlight enough to see properly.
• This lens acts to collect all electrons scattered from one point of the sample in one point on the fluorescent screen, causing an image of the sample to be formed.
• In its primary application of medical imaging, a "'fluoroscope "'( } } } } ) allows a physician to see the internal fluorescent screen, between which a patient is placed.
• The field emitted electrons travel along the field lines and produce bright and dark patches on the fluorescent screen giving a one-to-one correspondence with the crystal planes of the hemispherical emitter.
• Figure 1 to the right is a simple sketch of the path of a parallel beam of electrons in a TEM from just above the sample and down the column to the fluorescent screen.
• "' Transmission electron microscopy "'( "'TEM "') is a focused onto an imaging device, such as a fluorescent screen, on a layer of photographic film, or to be detected by a sensor such as a charge-coupled device.
• Fluoroscopy is an examination that involves a steady stream of X-rays passing through a patient and striking a fluorescent screen to produce light images, which can be recorded, magnified and enhanced to detect internal body function in motion.
• In the Geiger Marsden experiment, Hans Geiger and Ernest Marsden ( colleagues of Rutherford working at his behest ) shot alpha particles at thin sheets of metal and measured their deflection through the use of a fluorescent screen.
• Both live moving images and recorded still images were available from the very beginning with simple equipment; thus, both " looking with a fluorescent screen " (-graphy ) were immediately named with New Latin words both words are attested since 1896.
