We describe the accurate measurement of the radius of curvature of a concave mirror in a Fabry-Perot interferometer with a finesse of 78,100. The radius of curvature of the concave mirror is determined by measuring the free spectral range and the transverse-mode range with the frequency response...
We present a method to measure the radius of curvature of a concave conic asphere. By analysis the central area of the asphere, we can measure the radius of an arbitrary point in the central area instead of the vertex of asphere. In the procedure, we firstly adjust the interferometer until...

Noun1.radius of curvature- the radius of the circle of curvature; the absolute value of the reciprocal of the curvature of a curve at a given point radius,r- the length of a line segment between the center and circumference of a circle or sphere ...
The radius of curvature of a concave (make-up) mirror is 120 cm. How far must a person's face be located in front of the mirror so that her image is upright and four times the real size? What is the equation for displacement as ...

PURPOSE: To measure the radius of the curvature of a mirror surface having the spherical surface such as a lens surface highly accurately with a compact apparatus. ;CONSTITUTION: A moving distance Sw' of a holding part 105 for a material under inspection is detected with a length measuring par...
A crushing roller (1) in a housing (5) has axially spaced circles of alternating small and large projections (11,12). The housing wall (10) has a concave curved shape, whose radius of curvature is greater than the radius of the roller. The free edge of the housing wall lies within ...
A mirror with a curvature radius R of the surface has a focal length f=R/2, if the beam axis is normal to the mirror surface. (We take positive signs for concave curvatures and focusing mirrors.) If there is some non-zero angle θ between the beam axis and the normal direction, the...
