Abstract: An apparatus and method are introduced to produce a hologram of an object from electromagnetic radiation, such as incoherent light, received from the object. The electromagnetic radiation is received by a receiving assembly and transformed into a plurality of co-linear co-propagating beams with different focal distances. The interference of the plurality of beams is enabled by projecting components of each beam along a common polarization direction. The interference patterns thus formed are recorded and then processed to form the hologram of the object.

Abstract: An advance in high-resolution optical metrology has been achieved by the introduction of incoherent holographic imaging. FINCH, an example of incoherent holography, is shown to simplify the process, eliminating many steps in metrology and at the same time increasing throughput, resolution and accuracy of the method. A proposed technique requires only a single image capture with a non-moving camera rather than the capture of multiple stacks of images requiring many camera exposures and movement of the camera or sample in the conventional techniques.

Abstract: An apparatus for producing a hologram includes a collimation lens configured to receive incoherent light emitted from an object; a spatial light modulator (SLM) that includes at least one diffractive lens which is configured to receive the incoherent light from the collimation lens and split the incoherent light into two beams that interfere with each other; and a camera configured to record the interference pattern of the two beams to create a hologram, wherein a ratio between a distance from the SLM to the camera and a focal length of the diffractive lens is greater than 1.

Abstract: An optical apparatus comprising a plurality of lenses including a first lens affixed to an optics mount holder which is adjustably affixed to an alignment channel part is provided. The optical axis of the first lens passes through a hollow area of the alignment channel part. The lens is mounted on the optics mount holder which is adjustably affixed to one end of the alignment channel part with a plurality of adjustable fasteners. A method is provided for aligning the optical apparatus.
