Wide Incidence Angle Mirrors for LiDAR: II-VIs new mirrors enable reflected laser beams within LiDAR systems to maintain optical powers with a very high degree of uniformity over wide incidence angles ranging from 0 to 85 degrees.

During the image processing, a similar concentric-circle pattern is superimposed on the shadow and Moire fringes with spacing dependent on the incidence angle of a light beam are formed.
A crosswind gust creates a change in the incidence angle of the wind, which is the origin of undesired aerodynamic loads like side force and yaw moment.
By knowing these values in addition to source light incidence angle it becomes possible to predict direction of the outgoing light (or guide the light in direction that is required) after it passes the boundary between two different mediums.
994% that is attained when the incoming beam enters the element at a 0[degrees] incidence angle (e.
11[degrees] incidence angle, three diffraction peaks marked as (hOO) where, h = 1-3 corresponds to layered intra-chain P3HT orientation along a axis of crystallographic plane and (010) peak indexed the inter-chain [pi]-[pi] stacking orientation of P3HT backbone along [alpha]-axis of crystallographic plane (Fig.
In the continuous limit, it is proven that a PML interface between a regular medium and such a fictitious perfectly matched medium can completely absorbs incident waves from the regular medium, regardless of its incidence angle and frequency [10].

Its 2303 Visualiser uses a rotating assembly of LED lamps to illuminate the hologram being examined from all 360[degrees] in 1[degrees] increments, at an incidence angle of 30-60[degrees], with a field of view (FOV) of 29 x 22 mm at no magnification, which deliver 2260 dpi resolution.
For the radiometric distortions, earlier algorithms tried to perform the correction based on local incidence angle [21, 22] or surface tilt angles [23, 24].
