Evaluating mirror alignment systems using the optical sensing matrix

Evaluating Word Alignment Systems

Merit function regression method for efficient alignment control of two-mirror optical systems.

The precision alignment of high-performance, wide-field optical systems is generally a difficult and often laborious process. We report a new merit function regression method that has the potential to bring to such an optical alignment process higher efficiency and accuracy than the conventional sensitivity table method. The technique uses actively damped least square algorithm to minimize the ...

SOLVING FUZZY LINEAR SYSTEMS BY USING THE SCHUR COMPLEMENT WHEN COEFFICIENT MATRIX IS AN M-MATRIX

This paper analyzes a linear system of equations when the righthandside is a fuzzy vector and the coefficient matrix is a crisp M-matrix. Thefuzzy linear system (FLS) is converted to the equivalent crisp system withcoefficient matrix of dimension 2n × 2n. However, solving this crisp system isdifficult for large n because of dimensionality problems . It is shown that thisdifficulty may be avoide...

Evaluating Information Systems Alignment in Small Firms

Many studies of IS alignment have focused on the alignment between business strategy and IS strategy. This study is different to these prior studies as it develops a measure of IS alignment that is focused on business processes rather than business strategy. Therefore, it examines whether IS is aligned with business processes, i.e. the functional sub-component of the Henderson & Venkatraman (19...

Chemo-optical micro—sensing systems

Chemo—optical micro-sensing systems, whether based on fiber optics or integrated optics show promising prospects. The physical principles underlying chemo—optical waveguide sensors are discussed with the accent on linear evanescent field sensors. The role of the chemo-optical transduction layer is emphasized. Restriction of the freedom of design by technological uncertainties is briefly dealt w...
