The approach, called a catadioptric
optical system, would enable Apple glasses to project very large virtual content from a very small projector.
Don't try to guide a large reflector or catadioptric
telescope with a piggyback guidescope--use an off-axis (or on-axis) guider whenever possible.

omnidirectional vision," in Proc.
The network of national roads under the Northern Road Subdivision requires securing the implementation of concrete safety barrier in TPC and Annexes safety devices such as slot channels or catadioptric
Instead of using a reflective telescope, which is common in bathymetric lidar, they designed a catadioptric
telescope that uses mirrors and lenses to reflect and refract light.
So too are a two-tonne catadioptric
lens along with two tonnes of mercury.
The WASP CNVD features a 70mm Catadioptric
Lens System, and uses a LaRue Tactical LT105 Quick Detach Mount.
1) is similar--the prototype camera has a 20 cm catadioptric
EKF based attitude estimation and stabilization of a quadrotor UAV using vanishing points in catadioptric
images, Journal of Intelligent & Robotic Systems, Online First(tm).
The unique catadioptric
optical system maintains excellent color fidelity in all environments.
In common with SCTs, Schmidt cameras brought light to a focus using a catadioptric
combination of a refracting corrector plate followed by a spherical short-focal-length primary mirror.
lens sucks ambient light from near darkness and funnels it to an image-intensifier-tube photocathode.
