Abstract

The techniques, apparatus, material and systems are described for a portable camera device which can be attached to the camera port of a conventional transmission or reflection microscope for complex wave front analysis. At least one holographic element (BS, grating) splits the beam (s) containing the sample information in two beams (r,o) and filters (r', o′) them. The proposed invention has a relaxed alignment sensitivity to displacement of the beam coming from the microscope. Besides since it compensates the coherence plane tilt angle between reference and object arms, it allows for creating high-visibility interference over the entire field of view. The full-field off-axis holograms provide the whole sample information.
