High-Performance Spatial Light Modulator Control and Holography combines GPU-accelerated beamforming algorithms with optimized hardware control, automated calibration, and user-friendly scripting to enable high-performance programmable optics with modern spatial light modulators. Key Features • GPU-accelerated iterative phase retrieval algorithms (e.g. Gerchberg-Saxton, weighted GS, or phase-stationary WGS) • A simple hardware-control interface for working with various SLMs and cameras • Automated Fourier- to image-space coordinate transformations: choose how much light goes to which camera pixels; takes care of the rest! • Automated wavefront calibration to improve manufacturer-supplied flatness maps or compensate for additional aberrations along the SLM imaging train • Optimized optical focus/spot arrays using camera feedback, automated statistics, and numerous analysis routines • Mixed region amplitude freedom, which ignores unused far-field regions in favor of optimized hologram performance in high-interest areas. • Toolboxes for structured light, imprinting sectioned phase masks, SLM unit conversion, padding and unpadding data, and more • A fully-featured example library that demonstrates these and other features Installation Install the stable version of from PyPI using: Install the latest version of from GitHub using: Documentation and Examples Extensive documentation and API reference are available through readthedocs.
