v0.4.0

Changelog

v0.4.0 (March 2026)

Note: To better support our growing userbase, we are transitioning development and support of slmsuite to Holodyne Labs, Inc., which we founded to enable practical, real-time holography by combining high-performance algorithms and state-of-the-art spatial light modulators.

New Features

• Texas Instruments Phase Light Modulator (PLM) Support (texasinstruments.py): new implementation with GPU-accelerated phase processing (quantization and mapping) and USB control in #172
• FLIR Camera Support (flir.py): PySpin/Spinnaker SDK integration with QuickSpin API, auto-configuration, multi-bitdepth support (8–16 bit), WOI, GenICam nodemap traversal, and software trigger mode by @beneaze in #155, #172
• Renovated ScreenMirrored Implementation for Multi-SLM Setups (screenmirrored.py, _pyglet.py): now with a manager thread and dedicated event thread per SLM to prevent freezes in #172 (fixes #117)
• Meadowlark Enhancements: PCIe external trigger support, execute/block in _set_phase_hw(), _SDK_MODE enum with is_pcie, other modal support, firmware CSV update by @sumiya-kuroda in #136, #156, #159, #160 and in #142, #169
• Refined set_phase Control (slm.py): set_phase() now accepts execute (skip hardware write) and block (non-blocking for trigger workflows) in #172
• Build Modernization: migrated from setup.py/requirements.txt to pyproject.toml with optional dependency groups ([gpu], [slms], [cameras], [test], etc.) in #173, #174
• Testing Infrastructure: pytest framework with CI/CD, hardware fixtures, dynamic hardware selection, @pytest.mark.gpu/slow markers, and performance benchmarking in #173

Example notebooks have been updated to reflect/integrate these changes.

Breaking Changes

• autofocus() signature: parameter order reversed (set_z, get_z instead of get_z, set_z); z_list replaced by range_z; new metric and verbose params
• Build system: setup.py, requirements.txt, requirements_ipython.txt, MANIFEST.in removed — install via pip install slmsuite[gpu,slms] or uv sync --extra test
• remove_vortices now defaults to False
• binary duty_cycle corner case fixed (was inverted)

Bug Fixes

• NumPy 2.4 compatibility: .item() for scalar conversion, stricter indexing shapes, ptp() removal in #172, #173
• Pyglet>2.1.8 compatibility by changing datatypes in #172
• Meadowlark get_temperature(): SDK 3.x/6.x/8.x API mismatch and missing restype declaration by @sumiya-kuroda in #159 (fixes #141)
• Meadowlark Remote: stale phase → display parameter rename by @sumiya-kuroda in #156
• Basler WOI/buffer: unimplemented WOI, centering mode conflict, missing grab retry by @sumiya-kuroda in #136 (fixes #135)
• is_even inverted logic: bitwise NOT always truthy in Python in #173
• binary duty_cycle: inverted comparison and unclipped range in #173
• Stale Fourier calibration warning in #173 (fixes #133)
• ijcam_to_knslm in-place mutation of Fourier calibration by @philip-rk in #163
