Basically, the base materials for both types of screens are the same, with the difference being that pearl white screens are covered with tiny glass beads to enhance the reflection of light during projection. Generally speaking, if the light control in the viewing environment is not ideal, and ...
11.An object position calculation method used in a projector, comprising:detecting light emitted from an object which is on a projected screen;receiving a first sonic wave and a second sonic wave emitted from the object;when the object indicates calibration points displayed on the projected surface...
Hologram Calculation In some embodiments, the computer-generated hologram is a Fourier transform hologram, or simply a Fourier hologram or Fourier-based hologram, in which an image is reconstructed in the far field by utilising the Fourier transforming properties of a positive lens. The Fourier holog...
A few common throw distance or we say that the term we are using in the calculation for throw distance is as follows: Long Throw: If you have a large room and the screen size is big then you will enjoy your holidays with your family, Then a large throw distance projector becomes the ...
I'd want to mount upright with lens even with the top of the screen and shift down. Rob Sabin, Editor Posted Apr 4, 2021 10:40 AM PST Steve, I no longer have a sample available to precisely check the action on it, but I believe it had decent range down when it was placed on ...

Finally, we applied our method to shapes with curved surfaces and non-uniform texture as shown in Fig.14(left column). Those objects are placed between 250mm to 450mm from the projector. Fig.14 middle column shows the reconstruction results with five pixel intervals for fast calculation and ...

The required geometry may be determined by using an iterative wave-optical calculation. In particular, desired intensity distributions at different distances with respect to the optical elements may be used as a basis of the iterative design. Between different planes, e.g. VCSEL, optical element, ...
