Fringe projection profilometry and off-axis digital holographic interferometry are two techniques commonly used for non-contact optical surface measurement and movement tracking; however, they can be difficult to implement due to the complex software involved. To address this, we introduce a MATLAB-based graphical application that performs phase map retrieval for these techniques. Designed with a pipeline-based architecture, PhaseWare assembles the most commonly used algorithms and includes pre-processing (cropping, DC offset removal, filtering), fringe and phase extraction (hologram reconstruction, phase demodulation), and post-processing (denoising, masking, phase unwrapping, background removal, image enhancement).
