THIS work of Prof. Smith's has a “very practical purpose,” viz, “to present in simple and intelligible form a body of geometric doctrine, acquaintance with which may fairly be demanded of ...

We specifically demonstrate a hybrid nonlinear meta-lens composed of a plano-convex linear refractive lens coated with a 400 nm thick nonlinear metasurface membrane. We show that the resulting hybrid ...

\(power \ of \ a \ lens \ (D) = \frac{1}{focal \ length \ (m)}\) A lens has a power of -3.33 dioptres. Calculate the focal length and state what type of lens it is.

A key innovation is our Cycle-Domain Geometry-Integrated (CDGI) method, incorporating a Cone Beam X-ray Geometric Transformation Module (GTM) to ensure precise, synergistic operation between the dual ...

A single-element plano-convex lens is ... optical axes of the objective lens and the parabolic reflector. These image transformations can be compensated by post-processing the captured images using ...
