Before learning the dimensional formula, let us recall what is dimension. Dimension in maths is a measure of the length, width, or height extended in a particular direction. By dimension definition, it is a measure of a point or line extended in one direction. Every shape around us has ...
27,28], transmission elements [29,30], or display modules such as holograms [31,32]. These metasurface-based implementations, however, are generally constrained by small eyebox size and fixed focal length. To the best of our knowledge, no metasurface technology in AR displays has yet...
Structured light (SL)-based depth-sensing technology illuminates the objects with an array of dots, and backscattered light is monitored to extract three-dimensional information. Conventionally, diffractive optical elements have been used to form laser d
Analytical expressions for the optical properties of potential steps and barriers in the sharp and soft limits are known for a number of situations57, and we use here Cayssols39,57 interpolation formula that connects the two regimes, see Fig. 2b. As illustrated in Fig. 2c, the incident and...
a method for determining a human eye-watched object distance comprises the steps that according to a range which is covered on true environment by a virtual part of augmented reality, watched object distances si are calculated one by one by using far point and near point calculation formulae wh...
This definition of the 4th-order cumulant for zero time-lags comes from a combinational relationship among the cumulants of stochastic signals and their moments, and is given by the Leonov–Shiryaev formula, previously described in Eq. (6). The “minus 3” at the end of Eq. (21) acts as...
The formula can be derived from considerations of geometrical optics as can be found in [22], often used in photography. Then we calculated the diameter of the blur circle σb according to Eq. 2, depending on the distance d from the focal plane. In the final step, the position of the...
The zooming function, however, changes the focal length of the photo-detection lens which is one of the measurement conditions. Specifically, the value of the coefficient in the calculation formula of the distance data is changed. When obtaining the distance data by LUT, therefore, the LUT is ...
"X" can also represent additional stages of excitation where more than two-photon mechanisms are used. 3. In the formulae hv1 is a primary beam; hv2 a secondary beam; 1 A indicates an atom or molecule in ground state; 1 Av/r indicates an excited species in higher vibrational/rotationa...
18. The lens system of claim 17 wherein the lens system is adapted to operate when the slope of the first surface is set as a function of the focal length of the first and second lenses. 19. A method for focusing a camera for recording images with a first lens and a second lens ...
