Elements of Rings with Equal Spectral Idempotents
In this paper we define and study a generalized Drazin inverse x for ring elements x, and give a characterization of elements a, b for which aa = bb. We apply our results to the study of EP elements in a ring with involution. 2000 Mathematics subject classification: primary 16A32, 16A28, 15A09; secondary 46H05, 46L05.
متن کاملTwo-Photon Imaging with Diffractive Optical Elements
Two-photon imaging has become a useful tool for optical monitoring of neural circuits, but it requires high laser power and serial scanning of each pixel in a sample. This results in slow imaging rates, limiting the measurements of fast signals such as neuronal activity. To improve the speed and signal-to-noise ratio of two-photon imaging, we introduce a simple modification of a two-photon micr...
متن کاملAnalysis of blazed diffractive optical elements formed with artificial dielectrics.
A new hybrid method for the analysis of diffractive optical elements, which combines fully vectorial and scalar theories, is presented. It is suitable for use with elements of arbitrary large zone, even when the local feature size is of the order of the wavelength. To assess its applicability, we have performed cross-checking tests. The model is shown to accurately predict many optical properti...
متن کاملRefractive and diffractive X-ray optical elements
The planar microelectronics technology, involving lithography and highly anisotropic plasma etching techniques, allows manufacturing high quality refractive and diffractive lenses, which may be used in hard X-ray microprobe and microscopy applications. These silicon lenses are mechanically robust and can withstand high heat load of the white Xray beam at third generation synchrotron radiation s...
متن کاملSpecial Diffractive Optical Elements for Data Encoding
With the rising use of optical communication in different commercial as well as military systems, the issue of optical data security becomes eminent. There are two approaches for dealing with this need: using known encoding methods from electronic communication or developing optical encoding methods. In the first approach, the encoding may be done electronically before converting the informatio...
