centre of curvature Thesaurus n (Mathematics) the point on the normal at a given point on a curve on the concave side of the curve whose distance from the point on the curve is equal to the radius of curvature Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © Ha...
The screen envelopes the opening angle of the mirror. The heat reflecting screen (3) has a spherical shape with a centre of curvature which coincides with the optical centre of the mirror (1). The mirror is also surrounded by a reflector (4) which is spherical and also has its centre ...

This mirror has its focal distance periodically controlled by a piezoelectric action. The curvature remains practically spherical between the two extreme curvatures. The mirror (2) is fixed to the base (1) by a piezoelectric column (5 or 9), which is activated by an AC voltage, and by a ...
a bend can be considered a disturbance. At equal curvature, it is known that a bend in a Wn guide shows less loss than a bend in a Wm guide, with n<m. The mode converter of the invention advantageously permits the design of structures in which the propagation guide is a Wm guide in...
The system characterises by its position the centre point of a shutter, with the curved image field also concentric to the centre point. The curvature radius of the image field is equal to the system focal length. In the light path sequence, a collector spherical mirror projects an ...
The mirror with variable curvature, such as may be used in a solar reflector, comprises a flat reflective surface (1) made of a resilient material and a tensioning assembly (2) capable of acting thereon such that its deformation produces the required curvature. The assembly has a number of ...
