Compressive Interferometry for Optical Modal Analysis in Arbitrary Degrees of Freedom
نویسندگان
چکیده
Modal analysis of an optical beam refers to analyzing the beam into its constituent modes. In this paper, a new compressive approach for modal analysis of sparse beams using generalized interferometry in arbitrary degrees of freedom (DoFs) is proposed. It is shown that the modal content can be recovered by solving a sparse recovery problem based on random interferometric measurements obtained by sweeping the parameter(s) of unitary optical transformations that generalize the traditional temporal delay to an arbitrary DoF. The proposed compressive approach holds significant potential to reduce the computational complexity for modal analysis of optical beams in arbitrary DoFs using native optics hardware, namely two-path interferometry, with no need for extra hardware.

Generalized optical interferometry for modal analysis in arbitrary degrees of freedom.
We generalize the traditional concept of temporal optical interferometry to any degree of freedom of a coherent optical field. By identifying the structure of a unitary optical transformation that we designate the generalized phase operator, we enable optical interferometry to be carried out in any modal basis describing a degree of freedom. The structure of the generalized phase operator is th...

This paper develops a unifying framework for signal reconstruction from interferometric measurements that is broadly applicable to various applications of interferometry. In this framework, the problem of signal reconstruction in interferometry amounts to one of basis analysis. Its applicability is shown to extend beyond conventional temporal interferometry – which leverages the relative delay ...
متن کاملEfficient modal analysis using compressive optical interferometry.
Interferometry is routinely used for spectral or modal analysis of optical signals. By posing interferometric modal analysis as a sparse recovery problem, we show that compressive sampling helps exploit the sparsity of typical optical signals in modal space and reduces the number of required measurements. Instead of collecting evenly spaced interferometric samples at the Nyquist rate followed b...
متن کاملCompressive optical interferometry under structural constraints.
Compressive sensing (CS) combines data acquisition with compression coding to reduce the number of measurements required to reconstruct a sparse signal. In optics, this usually takes the form of projecting the field onto sequences of random spatial patterns that are selected from an appropriate random ensemble. We show here that CS can be exploited in 'native' optics hardware without introducin...

The subject of structural health monitoring and damage identification of structures at the earliest possible stage has been a noteworthy topic for researchers in the last years. Modal strain energy (MSE) based index is one of the efficient methods which are commonly used for detecting damage in structures. It is also more effective and economical to employ some methods for reducing the degrees ...
