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.
35 degree FOV (Field of View) or NIIRS 9 (National Image Interpretability Rating) with a high definition camera and large catadioptric
lens giving it the daylight equivalent of 15 inch gimbals that can weigh 100 lbs.
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).
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.
This revision includes a new overview chapter on aberrations, a rewritten chapter on automatic lens design, and an expanded chapter on mirrors and catadioptric
systems that incorporates a variety of newer systems, some with eccentric pupils.
Talks that day included Jim Hysom discussing a new type of catadioptric
telescope and David Allen, a professional astronomer from Cambridge relating his recent observing trip to do infra-red astronomy with the 30-inch reflector of the Physics Department of the University of Minneapolis in Minnesota, USA.
