We adjusted the knife and block angle until the block and knife were roughly aligned to each other, i.e., the distance between knife and block was consistent over the whole pyramid surface. The knife was then moved closer to the block and the alignment was refined. The boat of the ...
Using it, we first demonstrate multi-spectral programmable beam steering with FOV~18° and absolute efficiencies exceeding 40%. Then, we reprogram the device to achieve multi-spectral lensing with tunable focal distance and efficiencies ~27%. Our design paves the way towards a new class of SLM...
fairway woods (controlled long-distance shots) (iii) irons (for medium distance and accuracy) (iv) wedges (short-distance shots from sand and/or deep rough) (v) putters (getting the ball into the hole from the green) Although there are many kinds of golf clubs, they are basically compos...
a, Schematic of the experimental set-up. Multiline structured light is incident on the object; lens 1 and lens 2 capture the reflected light and pass it to perovskite nanocrystal arrays. A colour CCD then measures the colour of each azimuth detector to calculate the corresponding distance to t...
On the other hand, the average distance between two coordinate points (0 and x in Eq. 1) grows when q^2 shifting from large negative to positive values, and then the LD quark-gluon interaction forms the hadrons [5]. In this way, the correlation function can be expressed as the sum ...
First, the amplitude distribution of the input and output light fields and the imaging distance are determined. The diffraction formula and Gerchberg-Saxton algorithm are applied to calculate the phase distribution of the DOE in Matlab. Then the obtained phase distribution is input into the ...
Runconvert_depth2disp.pyandconvert_disp2depth.pyto convert between depth and disparity maps. You need to provide paths to the input and output map and to the scene parameter file. The corresponding formulas are: depth_mm = beta*focus_distance_mm / (disp_px*focus_distance_mm*sensor_size_mm...
The pattern of experimental measured and numerically simulated 3d intensity distribution within the z-distance of \(\lambda \) are shown in the middle part of Fig. 2a,b. With the same value of |l| and n for both beams, the Gouy phase35,36 of both beams is equal and, thus, the ...
Owing to its unique penetrating power and high-resolution capability, X-ray imaging has been an irreplaceable tool since its discovery. Despite the significance, the resolution of X-ray imaging has largely been limited by the technical difficulties on X-
For calculations of total effective dose for the different biological effects, the constants corresponding to each variable of equation have been included as the average effective irradiance by type of device (monitors, interior lights, smartphones/tablets and sun) at the standard distance, and we ...
