In optics, a conjugate plane or conjugate focal plane of a given plane P, is the plane P′ such that points on P are imaged on P′. If an object is moved...

the term confocal arises from the presence of a diaphragm in the conjugated focal plane (confocal) that is usually absent in multiphoton microscopes due...

the focal plane. Confocal microscopy uses a scanning point or points of light to illuminate the sample. In conjunction with a pinhole at a conjugate focal...

ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant...

the plane is a tangent plane. an ellipse or empty, otherwise. On the axis of a circular paraboloid, there is a point called the focus (or focal point)...

refractive index creates two conjugate foci outside the lens. The solution takes a simple and explicit form if one focal point lies at infinity, and the...

phase-conjugate beam, Ξ4. Its direction is given by k4 = k1 + k2 − k3, and so if the two pump beams are counterpropagating (k1 = −k2), then the conjugate and...

In mathematics, a hyperbola is a type of smooth curve lying in a plane, defined by its geometric properties or by equations for which it is the solution...

the exit pupil usually is unknown to the user of a lens, the rear conjugate focal distance is used instead; the resultant theoretical error so introduced...

PJ are tangent to C. When C is a real curve, only the intersections of conjugate pairs are real, so there are m in a real foci and m2 − m imaginary foci...

correctly, this matrix method will properly describe the positions of focal planes and magnifications, however aberrations still need to be evaluated using...
