Pseudocoloring method using two different spatial modulations.
Pseudocoloring o f gray level information is a technique for introducing false colore in a black-and-white transparency. The importance of this operation is based on the human eye’s ability to distinguish different colore better than gray levels. In the last few years several pseudocoloring optical methods have been proposed.1-10 Furthermore, the pseudocoloring technique has been extended to en...
متن کاملRCWA-EIS method for interlayer grating coupling.
The grating coupling efficiencies for interlayer connection (overlaid chips) were previously calculated using the new rigorous coupled-wave analysis equivalent-index-slab (RCWA-EIS) method. The chip-to-chip coupling efficiencies were determined for rectangular-groove (binary) gratings. In the present work, the search algorithms used in the RCWA-EIS method are optimized giving rise to improved d...
متن کاملCollimation method using a double grating system.
We present a collimation technique based on a double grating system to locate with high accuracy an emitter in the focal plane of a lens. Talbot self-images are projected onto the second grating producing moiré interferences. By means of two photodetectors positioned just behind the second grating, it is possible to determine the optimal position of the light source for collimation by measuring...
متن کاملAnalytical method for designing grating- compensated dispersion-managed soliton systems
We present a useful analytical method for designing grating-compensated dispersion-managed (DM) soliton systems for any desired input pulse widths and energies. The pulse-width and chirp evolution equations derived from the variational method are solved exactly to obtain the explicit analytical expressions for the length of the dispersion map and the grating dispersion. We also extend our analy...
متن کاملA simple parametric equation for pseudocoloring grey scale images keeping their original brightness progression
A new formalism to generate pseudocolor spectra is introduced. Therefore, a para-metric path in the RGB{color cube is derived to guarantee constant brightness progression. The resulting spiral{like curve allows the generation of various color spectra by adjusting the spiral's frequency and phase. The formalism allows the determination of the resulting number of colors in dependency of both para...
