產(chǎn)品簡介:
LETO相位調(diào)制器是基于一個(gè)反射LCOS微型顯示器與全HD（1920×1080像素）的分辨率。僅為6.4微米的像素間距和0.2μm的小像素間間隙的LETO SLM提供93％的高填充因子，從而高的光效率。

The LETO phase modulator is based on a reflective LCOS microdisplay with full HD (1920 x 1080 pixel ) resolution. With a pixel pitch of only 6.4 µm and a small interpixel gap of 0.2 µm the LETO SLM provides a high fill factor of 93% and thereby a high light efficiency.
The LETO Spatial Light Modulator is usable for the 400-1100 nm range and the modulator provides a phase shift of 2 π up to 850 nm. The device is delivered with a linear 256-level phase response for the specified user wavelength. The adaptation of the device settings for different operating wavelengths to a linear 2 π phase response can be done by straight forward gamma correction using the supplied calibration software.
The LETO Spatial Light Modulator offers a reflectivity of ~ 75%. Due to the optimized design of the LCOS microdisplay the LETO SLM shows low cross talk between the pixels resulting in high effective spatial resolution. The device offers diffraction efficiencies of more than 80% (16 level blazed grating) which leads to a total light efficiency of ~ 60%.

LETO Phase Modulator – Software Features:
The LETO phase only modulator devices can simply be addressed like an external monitor using the standard HDMI interface of the graphics card. No additional software or dedicated hardware is needed to operate the SLM.
For advanced callibration the LETO device uses a convenient standard USB interface and a Java based GUI callibration software. The software can be used to change the electrooptical response by applying a new gamma curve (to configure the device for use at a specific wavelength).
Besides that, a HOLOEYE SLM Application Software is provided with the device. Key features of which are:
Computation of computer generated holograms (CGH) from user defined images
generation of SLM signals representing basic optical functions such as lenses, gratings, axicon and vortex functions
superposition of CGH’s with basic optical functions to combine functionalities
