4.It may not work depending on the type of laptop.
In this case, there is a way to check the operation on a desktop PC.
5.Review the Windows display settings.
Due to the Windows display settings, LCOS-SLM may not receive DVI input correctly. Set the display
scale to 100% from "Scale and layout" in the display settings.
6.Review the display scaling settings.
Due to the display scaling settings, LCOS-SLM may not receive DVI input correctly. In the graphics board
control panel settings, Set 2nd screen output (DVI image output to LCOS-SLM) to "Maintain display
scaling"
Vertical lines appear on the LCOS-SLM head.
・
Check that the FPC cable is properly connected to the relay board.
Vertical lines may appear on the LCOS-SLM head if the FPC cable is not connected properly to the
junction board (Left and right half or the entire operating area). After turning off the power to the controller,
open the relay board cover and connect the relay board to the FPC cable again referring to page 14
"Connecting/Removing Equipment".
The desired diffraction pattern cannot be obtained.
・
Check the polarization direction of the incident light.
In the case of light perpendicular to the alignment direction of the liquid crystal or circularly polarized light,
the LCOS-SLM may not operate or the desired diffraction pattern may not be obtained.
・
Check the wavelength of the readout light.
If the product is used at wavelengths other than those set at the time of shipment, the desired diffraction
pattern may not be obtained, or reflectivity and light resistance may decrease.
・
Check if the distortion correction pattern is correct.
Make sure that the addition is done correctly.
Also, check whether the correction pattern is suitable for your laser.
・
Check that the correct phase image considering the phase modulation characteristic is
prepared.
Make sure the process is done correctly.
It is also necessary to perform wavelength coefficient conversion corresponding to the laser used.
The FPC connector on the relay board was damaged.
If the relay board is damaged due to a factor that is not covered by the warranty, it is recommended to
purchase the relay board separately.
