numerical integration based upon the relation between the radial direction position of an image on the imaging surface of the camera 5 and the angle of light impinging on the concave surface mirror 1 to the horizontal according to user's demands (projection relation with an object to be imaged...
摘要: PURPOSE:To enable higher diffused reflecting efficiency by forming the convex and concave surface in narrow width on one surface of a transparent plate, and forming that in broad width and extending toward one direction on another surface, and by providing thin film with good reflection....
PROBLEM TO BE SOLVED: To provide a reflecting mirror which is excellent in heat resistance, secures a sufficient surface accuracy, has a reflective surface with a surface roughness small enough to be coated with a vapor deposition film without being polished, can have a larger effective reflective...
1.an optical instrument for making distant objects appear larger and nearer when viewed directly through lenses (refracting telescope) or indirectly as through images focused by a concave mirror (reflecting telescope). adj. 2.consisting of parts that slide one within another. ...
13.6 Reflection of a point source from a plane Here we consider what happens when a point source is placed near an infinite reflective planar boundary. Essentially, a hard reflecting surface is the acoustic equivalent to a mirror in optics whereby each reflecting element on its surface acts as ...

Mirrors may have plane or curved surfaces. A curved mirror is concave or convex depending on whether the reflecting surface faces toward the centre of the curvature or away from it. Curved mirrors in ordinary usage have surfaces of varying shapes. Perhaps the most common is spherical. Spherical...
