This configuration--known in physics as Maxwell's fish-eye
lens--is a theoretical construct that is only slightly similar to commercially available fish-eye
lenses for cameras and telescopes.
A general tendency of the fish-eye
cracks was to grow in opening mode I as revealed by the orientation of the crack plane that changed from being perpendicular to the specimen's longitudinal axis for pure bending to a tangential inclination (along the circumference) of ~45[degrees] for torsion.
lenses for any measurement purpose, a large amount of distortion should be taken into consideration, modeled and mitigated.
Recording a narrative verdict, the jury said: "We believe the fish-eye
lens was unsuitable for purpose.
To ensure the panoramic camera captures the same scene content that the PTZ camera covers, the fish-eye
camera is fixed inclining towards the gravity direction (Figures 3(a)3(c)).
Student Greg Dash's Lofi Fish-Eye
camera is little over 4cm long and 2cm high, has only one button and no LCD screen.
Platinum Pac: A premium, specially coated PAC designed for easy mixing without fish-eye
You then screw on the special lens and you can take 180-degree fish-eye
snaps on your mobile.
Accurate sample positioning is supported by a fish-eye
chamber camera and an integrated light microscope with 10X and 100X magnifications.
In practice such a distribution can be acquired with fish-eye
lens equipped camera.
The two fish-eye
lenses house a new infrared array detector which enhances performance with regard to the range at which a missile firing will be detected, offer improved rejection of false alarms and give an angular localisation capability which will be compatible with the future use of Directional Infrared Counter Measures (Dircm).
