Cube polarizer with minimal optical path length differenceThe cube polarizer can have modified prism dimensions to satisfy the following equationAustin HuangDean ProbstBin WangHua Li
The integer A gives the number of wavelengths in the path-length difference. Waveguide gratings are usually operated at a high grating order; A is often on the order of 100. The above equation can be read as follows: The phase accumulation in the path-length difference between successive ...
where β = 2πn/λ is the propagation constant, n is the refractive index, ΔL = L1 − L2 is the length difference between the two arms, and ω is the optical frequency. φ1 and φ2 are the initial phase shift of the two arms, which can be introduced by the beam splitter as ...

In case of positive bias, the background in a DIC image is mid-gray and the optical path length differences are bright on the one side and dark on the other side of the objects. However, the microscope can be set to extinction based on the position of the first prism, when regions ...
In a simple case with light traveling through a homogeneous, we have the simple equationΛ=n⋅d The concept of optical path length can be misleading, e.g. in the context of light propagation in waveguides!where n is the refractive index and d the geometric path length. This can be ...
In a concurrent development, two non-intersecting paths interacting with a wall have been examined in semi-infinite space using a set of partial difference equations.Here, we review this partial difference equation method for the case of one path in a half plane. We then demonstrate that the ...
Average Path Length refers to the average distance between any two nodes in a graph. It is a measure that helps to understand the structure and connectivity of the graph. The concept of Average Path Length is significant in various applications such as social networks, where it highlights the ...
Assuming that the base element 42 is homogeneous, the only dimension of interest to the optical path length difference is the dimension "L" of the extension element 44. Equation (1) continues to apply. However, the refractive index "n1 " is taken as unity and the refractive index "n2 " ...
For a non-absorbing mobile phase, Equation 16 leads to: Aintercept=log [1/1+X], and Aroll-off=log[1/k] which allows X and k to be estimated from the calibration curve. Table I is an example of the dependence of Aintercepton mobile phase absorption. The pathlength ratio is j=0.01...
