slmsuite
Python package for high-performance spatial light modulator (SLM) control and holography. Supports features from aberration-corrected 3D point clouds to automated Fourier-domain calibrations.
High-Performance Spatial Light Modulator Control and Holography
slmsuite 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;
slmsuitetakes 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
