Light Scarring in an Optical Fiber
Physical Review Letters, 2001We report the first experimental study of wave scarring in an optical fiber with a noncircular cross section. This optical multimode fiber serves as a powerful tool to image waves in a system where light rays exhibit a chaotic dynamics. Far-field intensity measurements are used to provide a better identification of scars in the Fourier domain.

Optical binding in white light
Optics Letters, 2015We experimentally demonstrate, for the first time, binding of aerosols of various sizes and shapes in white light. The optomechancial interaction between particles is long range and is in the underdamped regime. Incoherency allows mitigation of interference fringes to enable monotonically changing the distance between particles from 60 μm to contact ...

Stray Light in Optical Systems*
Journal of the Optical Society of America, 1947An objective method has been developed for measuring the stray light in optical systems. Stray light reduces the contrast of image and falsely appears to augment the light transmission of optical system. The method utilizes a photoelectric apparatus to compare the contrast of an image formed by an optical system with the contrast of the object under ...

Light utilization in optical correlators
Applied Optics, 1982An analysis is made of the overall light efficiency in a coherent optical correlator. The results are applied to a matched filter and an inverse filter. Kogelnik's coupled wave theory is applied to analyze the diffraction efficiency of a filter recorded on a high-efficiency phase medium such as dichromated gelatin.

The light microscope as an optical diffractometer
Journal of Cell Science, 1967ABSTRACT The analysis of electron micrographs by optical diffraction was introduced recently by Klug & Berger (1964). Their experiments were conducted with a special diffractometer designed for use with diffracting masks up to several inches in diameter.

Light Distribution in the Optical Image*
Journal of the Optical Society of America, 1947A method is proposed for obtaining information about the light distribution in an optical image. The characteristic function of the optical system is approximated by a polynomial, containing terms up to the fifth or seventh order. The coefficients of this function having been found, a large number (about 100) of rays from an object point are chosen, so

Optical resolution and the duality of light
Applied Optics, 2008For 15 years, lensless microscopes have been constructed based on the use of holography, a digital CCD detector, and a computer for image reconstruction by use of, e.g., Fourier transformation. Thus, no lens is involved and therefore the conventional resolution limit of half the wavelength no longer applies.
