Most 3-D laser scanners are based on 3-D optical triangulation algorithms, where the location of each 3-D point is estimated as the intersection of a camera ray and a plane of light projected by a laser line generator. Since a physical laser-line gen

In his beautiful paper, Hasan Fakhruddin reported observations of mirror-like reflections in the rough surface of a ground glass plate. Similar effects have been recently employed for metrology of the roughness of optical diffusers used in modern lig

In atomic force microscopy (AFM) metrology, the tip is a key source of uncertainty. Images taken with an AFM show a change in feature width and shape that depends on tip geometry. This geometric dilation is more pronounced when measuring features wit

We investigate a water-filled bottle rolling down an incline and ask the following question: is a rolling bottle better described by a model ignoring all internal motion where the bottle is approximated by a material point sliding down an incline, or

We present a novel, high incidence angle metrology tool for in-situ characterization of diffusers for light emitting device manufacturing. This metrology tool can be easily integrated on the side windows of the process chamber and is insensitive to v

We have built a novel oblique angle scatterometer designed and optimized for measurements of rough surfaces having a root mean square roughness value (RMS Roughness) on the order of 100 nm – 1000 nm or larger. The majority of existing techniques fo

We measured and analysed the stability of two types of soap films suspended on two rings using the simple conical frusta-based model, where we use common definition of conical frustum as a portion of a cone that lies between two parallel planes cutti

A large numerical aperture (NA in range 0.65-0.8), diffraction limited, broadband (100 nm - 30,000 nm), all-reflective confocal microscope objective design is discussed. The design is compatible with engineered polarization state of the excitation be

Late results of surgical treatment are reported in a group of 140 patients operated for clear-cell renal carcinoma in the years 1960–1974. The mean survival time was 5.61 years for males and 6.59 years for femals which is, respectively, 14.19 years
