Phasics Camera

This service operates a Phasics SID4 camera using the Phasics SDK for communication and PySID4x python library. It handles image acquisition, and by default returns Phase Maps as images. For raw intensity values see the ‘intensity’ data stream.

Note

The Phasics Camera requires the Phasics SDK and PySID4x Python package to be installed and configured correctly. To get a copy of the Phasics SDK and PySID4x python package please contact Phasics directly for customer support.

Configuration

phasics_cam:

service_type: phasics_cam simulated_service_type: phasics_cam_sim interface: camera mode: normal mask: !path “../../data/phasics/2025-01-28 full aperture.msk” usr_profile_path: C:/path/to/SID4_SDK_x86_64/Examples/UserProfiles/SID4-1481/SID4-1481.txt wavelength: 633.0 buffer_frames: 16 requires_safety: false exposure_time: 504

exposure_time: Exposure time in milliseconds.

mode: ‘normal’ mode operates the camera. ‘dummy’ mode generates fake data for testing signal chain.

wavelength: The wavelength in (nm) of the camera

mask: the location of the camera mask

usr_profile_path: the location of hte SID4 SDK user profile

buffer frames: number of buffered frames in the catkit2 datastream

Properties

None.

Commands

take_measurement: Acquires a single measurement from the Phasics camera.

start_acquisition: Begins continuous image acquisition from the camera.

end_acquisition: Stops the continuous image acquisition.

phase_filtering: Applies phase filtering to the acquired images using supplied zernike projection coefficients

phase_projection: Performs zernike phase projection on the acquired images.

Datastreams

images: The acquired (Phase map) images from the Phasics camera.

is_acquiring: Indicates whether the service is currently acquiring data (True for acquiring, False for not acquiring).

intensity: The acquired intensity images from Phasics camera.
