slmsuite - v0.3.0

New Features

• Added a new interface for Meadowlark that is compatible with the different types of SDKs (HDMI, PCIe, ...). Thanks to @darikoneil , @nobias , and Anna at Meadowlark.
• Completed the interface for Holoeye SLMs. Thanks to @mkm2 .
• Added a USB interface for Hamamatsu SLMs. Thanks to @ninovarde .
• Added remote interface where a Server can host cameras and SLMs which clients can connect to with RemoteCamera and RemoteSLM. For instance, I had a 20 MP camera that for whatever reason wasn't playing nicely with the computer with the GPU and SLMs, so this feature allows that camera to be hosted on a different computer. This feature was inspired in part by slmpy's server.
• Made Camera and SLM explicitly abstract as a resolution to #92 .
• Fixed a bug with Thorlabs for 0.2.0+. Thanks to @calebrich .
• Modified binary to accept vectors with coordinate larger than 1, which are interpreted as instead pixel_periods for the gratings.
• Added quadrant and bahtinov alignment masks. Thanks to @bodokaiser for suggesting quadrant.
• Started the process of typehinting (this will continue to the rest of the package if it looks alright) and autodocing the types.
• Minor bugfixes with datatyping, documentation,
• Fixes and upgrades to CompressedSpotHologram.
• take_tile to tile a stack of images into a grid. Faster useful alternative to and within take_plot.
• Other imaging functions.
• Crosshair feature for live cameras.
• Updated package citation and badges.
• Assorted documentation.

slmsuite - v0.1.0

New Features

• Simulation of hardware with SimulatedSLM and SimulatedCamera, modeling experimental effects.
• New toolbox.phase functions
  • sinusoid() grating.
  • binary() grating.
  • 2D general polynomial().
• Fitting the SLM's source amplitude data to recenter grids and derive scales.
  • For instance, functions like lens() which use the SLM grid are now centered on the source amplitude and will focus coaxially.
  • This also is now used in choosing a radius for structured light conversions and Zernike data (see next).
• Revamped Zernike functionality.
  • New convert_zernike_index() function to convert between common indexing standards.
  • Auto-choosing a good Zernike aperture from fitted source amplitude data.
  • Zernike derivatives (computed via the chain rule, so fast).
• 3D support for convert_vector() (previously known as convert_blaze_vector()) and new units, including:
  • "zernike", which expresses 3D points as the result of coordinates (in radians) directly multiplied with normalized tilt and focus Zernike polynomials.
  • metric units in camera-space, making use of knowledge of the camera pixel size and magnification between the camera and experiment.
• 3D spot arrays CompressedSpotHologram. #41
• Spot arrays with unique Zernike aberration compensation for every spot (generalization of the above). Every spot goes to the desired point in 'aberration space'.
• Conjugate gradient optimization of holograms using pytorch working alongside cupy.
• Quadratic initial phase guess (instead of random) to promote a smoother hologram.
• Multiplane holography with the meta-hologram MultiplaneHologram, which simultaneously optimizes the objectives of multiple child holograms.
• Experimental holography features:
  • remove_vortices() and optical vortex analysis tools to remove phase kinks from the farfield.
  • get_multiplane_defocus_blur() for realistic defocus.
• Wavefront calibration wavefront_calibrate() that simultaneously measures at multiple calibration points.
  • When combined with the above, implemented #60 in spot arrays.
  • This also includes other updates to wavefront calibration #42
  • New calibration algorithm based on removal of Zernike terms.
• More robust fourier_calibrate() fitting.
• pixel_calibrate() measuring phase swing and crosstalk.
• settle_calibrate() measuring the $1/e$ SLM settle time.
• Revamped CameraSLM calibration internal storage and saving.
• format_2vectors() generalized to format_vectors() with N-dimensional support.
• Allow moments to accept arbitrary grids, among other small changes.
• Divide and conquer algorithm for smallest_distance() (now can handle millions of points in $O(N\log N)$ time).
• Artificial bitdepth enhancement for cameras:
  • Multi-exposure High Dynamic Range imaging,
  • Software averaging.
• Upon get_image()error, cameras now try again capture_attempts times. This improves reliability against rare errors.
• SLM, Camera, and CameraSLM subclasses now have default plotting .plot() method that makes it easy to see what's happening in the phase and image domains.
• Holograms also have improved .plot_farfield() enabling different units and helper boxes.
• Added untested #17
• Added skeleton for #26
• Docs have moved from the readthedocs theme to the very nice pydata theme (used by numpy, etc).
• Lots of documentation cleanup and polishing.
• The package index moved from QPG-MIT/slmsuite to slmsuite/slmsuite.

Breaking Changes

• Changed toolbox.phase functions:
  • zernike() and zernike_sum() are completely changed.
  • blaze() had the offset= parameter removed as it was redundant with +=.
• Renamed variables in cameras and SLMs to reduce clutter:
  • dx_um, dy_um -> pitch_um
  • dx, dy -> pitch
  • x_grid, y_grid -> grid
  • phase_correction, measured_amplitude, -> source
  • Constructors are also modified in some cases.
  • Default parameters are changed in most cases.
  • High-level SLMs (Santec, Meadowlark, ...) should largely be fine, but direct calls to the SLM constructor might break.
• Renamed variables in Holograms:
  • method was moved to flags.
  • extract_phase() and extract_farfield() -> get_phase() and get_farfield().
• Renaming in FourierSLM:
  • Different calibrations are now stored in a single dict calibrations.
  • Saving was revamped to use a single method to save all calibrations to avoid method bloat as calibrations are added.
  • For instance save_wavefront_calibration() and load_wavefront_calibration() is now changed to write_calibration("wavefront_superpixel") and read_calibration("wavefront_superpixel") or write_calibration("wavefront_zernike") and read_calibration("wavefront_zernike").
  • wavefront_calibrate() has renamed and reorganized variables.
  • In particular interference_point -> calibration_points.
  • Processing methods were also renamed for better organization. For instance process_wavefront_calibration() -> wavefront_calibration_process()
• Assorted general attempts at improving packaging naming uniformity.
  • For instance, using get_ and set_, read_ and write_, etc as the dominant language.

Bugfixes

• Warning for #49
• #53
• #62
• #63
• #73
• Many small things.

Under the Hood

• Major reorganization of internal files.
  • algorithms is split into many smaller files.
  • fitfunctions and files are moved from misc to analysis and toolbox.
• Introduced a number of custom CUDA kernels (in cuda.cu).
