<p>Method and apparatus of producing images of an object are disclosed. Phase data relating to an object is obtained by detecting a radiation wavefield and processing data relating to the detected field to produce phase data relating to the object. Various image modalities can then be produced by further processing the phase data to produce a particular phase visualisation modality image relating to the object. Such images include Hoffman modulation contrast images, differential interference contrast images, Zernike phase contrast images, Dark Field contrast images, and Darkground images. The method and apparatus also enables the production of intensity modulated images by obtaining intensity data and modulating the image with that intensity data. Enhancement can be supplied to both the phase data and the intensity data if required.</p> |
