They have illuminated first focal plane
reticles with six levels of brightness and Tactical Zero Turret Stops.
For the shortwave band, there is a minimum spot diameter of 3.7 mm at 5.5 mm above the focal plane
. The minimum spot diameter is the same as 0.8 mm of the middle and long wavelengths, but the location is slightly different.
The acceleration, velocity, and trajectory in plane are shown in Figure 2 and the sketch map of focal plane
imaging is shown in Figure 3.
As referred in the derivation of (10), the fluorescent signals are conceived to come from the focal plane
. Consequently, if the focal plane
is not located at the true depth of target, the image restoration will result in a virtual target in the focal plane
and the location of this virtual target varies with DFP.
According to the relationship between temperature data and focal plane
position provided by optical analysis (1), an estimated position of the focal plane
Just keep in mind the reticle is located in the rear focal plane
, so the BDC is calibrated at 4X.
FT-IR microscopes equipped with a Focal Plane
Array Detector are very rare.
To complete spectrum coverage, Flir has the Tau camera, which incorporates 640x512 or 320x240 Indium Gallium Arsenide (InGaAs) 25-micron pixel pitch focal plane
array, both weighting only 130 grams with M24 lens mount making ideal for small vehicles and battery-powered viewers.
They will then have to travel further before overlapping, so the overlap will occur beyond the focal plane
. With a Risley prism-pair the effective apex angle can be increased, by adjusting the relative orientation of the two component prisms, to bring the overlap point back to the focal plane
IRC offers commercial and customizable cameras, OEM cores and IDCAs that utilize the most sophisticated digital focal plane
technologies, providing the highest sensitivity and fastest frame rates.
When the focal plane
[z.sub.f] is chosen as the height z of the target P(x, y, z), i.e., [z.sub.f] = z, the 2D image about the target is a focused point; otherwise, when [z.sub.f] [not equal to] z, the result shall be a defocused ring.
The stereoscopic sheet structure has a convex lens assembly which is formed on one surface of a sheet member and in which a plurality of convex lenses are arranged; and a repeating design portion in which a plurality of design units are arranged on a focal plane
of the convex lenses at arrangement intervals and/or in arrangement directions different from those of the convex lenses, and which has a continuously deformed design portion in which the arrangement intervals and arrangement directions of the design units regularly change.
