Responses of simple optical standing wave sensors
Victor-Otto de Haan, Rudi Santbergen, Martijn Tijssen, Miro Zeman
Optical standing wave sensors have been manufactured by amorphous silicon deposition. The responses of these sensors, when subjected to standing waves, have been calculated and measured. It is shown that the responses are different depending on the way the standing wave is created. The responses ... [Appl. Opt. 51, 3109-3113 (2012)]

Loss and modal properties of Ag/AgI hollow glass waveguides
Carlos M. Bledt, James A. Harrington, Jason M. Kriesel
Hollow glass waveguides, composed of Ag/AgI coatings, have been studied at 10.6 µm. The losses for different bore sizes equal the theoretical loss, which for the 700 µm bore guide was about 0.15??dB/m. The losses for the guides increase upon bending, varying linearly with increasing ... [Appl. Opt. 51, 3114-3119 (2012)]

Accuracy enhancement of 3D profilometric human face reconstruction using undecimated wavelet analysis
Fatemeh Mohammadi, Khosro Madanipour, Amir Hossein Rezaie
Three-dimensional profilometric object reconstruction is a challenging topic; among the various methods available, we implement the line projection technique, which has superiorities over other methods. In order to increase the accuracy of measurement, a wavelet transform analysis is used in two ... [Appl. Opt. 51, 3120-3131 (2012)]

Aligning a reflection cavity by Anderson?s method
Robert D. Reasenberg
The sounding rocket principle of equivalence measurement uses a set of four laser gauges operating in Fabry?Perot cavities to determine the relative acceleration of two test masses that are chemically different. One end of each cavity is a flat mirror on a test mass. Because the test masses ... [Appl. Opt. 51, 3132-3136 (2012)]

Relaxation of the Talbot condition in generalized grating imaging
Koichi Iwata, Kazuo Satoh, Kousuke Moriwaki
We can form a grating image with two gratings having different pitches with an extended light source. It is called generalized grating imaging or the Talbot?Lau effect. When we want to obtain high contrast image with pure absorption gratings or pure phase gratings, the separation between the ... [Appl. Opt. 51, 3137-3144 (2012)]
