A dichromated gelatin off-axis Fresnel zone plate (OFZP) was designed, fabricated, and used in a new type of interferometer for optical metrology. This single hologram optical element combines the functions of a beam splitter, beam diverger, and aber

The objectives of the Low Cost Microsensors (LCMS) Program are twofold. The first is to develop and deliver a long-range infrared (IR) sensor built upon an uncooled vanadium oxide (VOx) 640 X 512 format focal plane array (FPA) engine. The second is t

A thin lens analogy between holographic optical elements, including transmission, reflection, flat, and curved holographic optical elements, and conventional optical elements is discussed. Examples show that a thin lens model of a holographic optical

A general thin lens analogy between a holographic optical element (HOE) and a conventional optical element (COE) is discussed. The third order aberration theory of a HOE is given. The generalized aplanatic condition of the HOE is derived and shows th

The Phase Measuring Interferometer (PMI) technique has been adapted to the measurement of small scale features of very high quality (low scatter) optical surfaces. The method described has good vertical and lateral resolution over a wide range of fie

Conference on Lasers and Electro-Optics.
Using two-wavelength interferometry with a recyclable thermoplastic holographic camera we have developed an interferometric technique for real time contouring of fast aspherical surfaces. The setup of this interferometer will be discussed.
