A new type of interferometer for producing fringes with spatially incoherent light was invented, which can be used for construction of HOEs. A method for forming HOEs of very high diffraction efficiency and low noise was developed. THe new superresolution discovery was explored, and significant experimental verification was carried out. A new method of image formation through inhomogeneities was discovered and experimetally verified. This method is based on the technique of superresolution by incoherent conversion. An incoherent spatial filtyering techinque was developed for use with spatially incoherent white light. This technique was extended to the use of real world, reflecting, three-dimensional objects.
