angular spreadの例文

• Photons of 500 nm from a certain direction will have an angular spread of the order of 500 nm / 5 cm = 10 ^ (-5 ) radians.
• The angular spread can be maintained within this range by contributions from the beam spot size; however, the solid angle geometry of the detector is only 0.04 msr.
• Luminous flux is not used to compare brightness, as this is a subjective perception which varies according to the distance from the light source and the angular spread of the light from the source.
• For example, if one estimates " ?? " for a scattering angle of 37.5?causing a kinematic energy shift comparable to typical detector energy resolutions of 1 %, the angular spread " ?? " must be less than 0.4?
