Software

HOLOEYE’s GAEA 4K phase-only modulators are designed for straightforward integration, functioning like a standard external monitor via a graphics card’s HDMI interface. They require no special software or hardware to operate.

For advanced adjustments, the device includes a Graphical User Interface (GUI) Configuration Manager. This software connects via USB and allows users to modify geometric settings, brightness, contrast, and electro-optical response, including applying new gamma curves or digital drive schemes.

Additionally, HOLOEYE provides a SLM Pattern Generator software for:

• Creating computer-generated holograms (CGHs) from user-defined images.
• Generating SLM signals for fundamental optical functions such as lenses, gratings, axicons, and vortex functions.
• Combining CGHs with basic optical functions.

The device also comes with a SLM Slideshow Player software. For developers, an SLM Display SDK is available, offering APIs for direct image and data/phase array display on HOLOEYE Spatial Light Modulators. Supported programming environments include:

• National Instruments LabVIEW™ (8.6 and later)
• MathWorks MATLAB® (R2009b and later)
• Octave (5.2)
• Python™ (2.7 and 3.x)
• C or C++ compilers (e.g., Microsoft Visual C++ Compiler)
