Caption: First Focal Plane
reticles have recently become more popular, especially among long-range target shooters, because the distance between hashmarks stays the same compared to the target regardless of magnification.
If the greater field of view is key criteria for scope use and the target will likely be inside 500 yards, second focal plane
reticles are definitely the way to go.
With Burris's Dual focal plane
design the center illuminated section is in the rear focal plane
The fundamental principle of the automatic focusing system based on image processing method is to count corresponding image focus evaluation function (FEF) value to each focal plane
position, and the corresponding position of the maximum FEF value is the best imaging focal plane
The only drawback to this design is the distance to the focal plane
requires a slightly larger diagonal mirror (2.
FT-IR microscopes equipped with a Focal Plane
Array Detector are very rare.
They will then have to travel further before overlapping, so the overlap will occur beyond the focal plane
The thrust forward will be to integrate the construction of a highly efficient thermoelectric device with that of an infrared focal plane
array thus providing effective cooling directly to each individual pixel.
This compresses the focal plane
array, causing specially designed electrical interconnects to delaminate from the rubber surface and form arcs, pinned on the ends by detector pixels.
The lens is designed to focus the visible and invisible infrared light rays onto a single focal plane
Anatomy within the focal plane
, a u-shaped zone between the x-ray source and the film, appears with the least amount of distortion.
The 160 X 120 pixels microbolometer focal plane
array with a pitch of 35[micro] and a spectral response of 8[micro] to 14[micro], is adapted for low-cost thermal imagery and medium spatial resolution for military and civil applications.
