parallel beam in a sentence

Examples

1. If the particle has a higher refractive index than the liquid surrounding it then it behaves as a convex lens and focuses a parallel beam of light on the side opposite the source of the light.
2. The principle of parabolic reflectors has been known since classical antiquity, when the mathematician Diocles described them in his book " On Burning Mirrors " and proved that they focus a parallel beam to a point.
3. The empennage was carried on four parallel beams extending two each from the top and bottom wings, and consisted of twin rudders and a horizontal stabiliser and elevator that were carried on the top two beams.
4. The conceptually simplest geometry referred to as selected area electron diffraction ( SAED ) is that of a parallel beam of electrons incident on the specimen, with the specimen field selected using a sub-specimen image-plane aperture.
5. In traditional dark-field imaging ( in a parallel beam mode, not STEM ), an objective aperture is placed in the diffraction plane so as to only collect electrons scattering through that aperture, avoiding the main beam.
6. In the process, an X-ray sensitive polymer photoresist, typically PMMA, bonded to an electrically conductive substrate, is exposed to parallel beams of high-energy X-rays from a synchrotron radiation source through a mask partly covered with a strong X-ray absorbing material.
7. A typical glossmeter consists of a fixed mechanical assembly comprising a standardised light source that projects a parallel beam of light onto the test surface to be measured and a filtered detector located to receive the rays reflected from the surface, Figure 1.
8. Parallel beam irradiation optical system may be the easiest and most practical example of a tomographic optical system therefore, in this article, explanation of " How to obtain the Tomographic image " will be based on " the parallel beam irradiation optical system ".
9. Axicons have been used by the research team at Beckman Laser Institute and Medical Clinic to focus a parallel beam into a beam with long focus depth and a highly confined lateral spot, to develop a novel optical coherence tomography ( OCT ) system.
10. Parallel beam irradiation optical system may be the easiest and most practical example of a tomographic optical system therefore, in this article, explanation of " How to obtain the Tomographic image " will be based on " the parallel beam irradiation optical system ".
