Focal shift, optical transfer function, and phase-space representations.
The focal shift for a lens of finite value of Fresnel number can be defined in terms of the second moment of the intensity distribution in transverse planes. The connection with the optical transfer function is described. The specification of the focused amplitude in terms of the fractional Fourier transform is discussed, and the connections among the fractional Fourier transform, the Wigner di...
متن کاملFocal shift in vector beams.
We examine the three-dimensional intensity distribution of vector Bessel-Gauss beams with general polarization near the focus of a nonaperturing thin lens. Recently reported linearly and azimuthally polarized Bessel-Gauss beams are members of this family. We define the width and focal plane of such a vector beam using an encircled-energy criterion and calculate numerically that, as for scalar b...
متن کاملSignal amplification and control in optical cavities with off-axis feedback.
We consider a large class of optical cavities and gain media with an off-axis external feedback which introduces a two-point nonlocality. This nonlocality moves the lasing threshold and opens large windows of control parameters where weak light spots can be strongly amplified while the background radiation remains very low. Furthermore, transverse phase and group velocities of a signal can be i...
متن کاملComputer-generated holograms for optical neural networks: on-axis versus off-axis geometry.
For optical neural networks implemented with computer-generated planar holograms the spacebandwidth product of the hologram is a major consideration. Off-axis holograms can be fabricated with a single binary transmission mask. However, the carrier frequency greatly increases the space-bandwidth product. On axis-holograms use a lower space-bandwidth product to encode interconnections but require...
متن کاملMeasurement of Multitasking with Focus Shift Analysis
Perhaps one of the most prevalent, yet least understood, forms of modern behavior is human multitasking aided by technology. Multitasking is both difficult to define and to measure. Based on Activity Theory and the concept of focus shifts, this study defines multitasking as shifts that occur when the flow of work is interrupted and tasks are interchanged during a session. The analysis of focus ...
