Abstract Background The shape and microstructure of the human crystalline lens alter with ageing, and this has an effect on the optical properties of the eye. The aim of this study was to characterise the age-related differences in the morphology and

In this paper, we present age-related changes in the crystalline lens and investigate which OSD zones are more responsible for changes in the lens’s morphology and transparency with ageing. We present both qualitative image and quantitative data an

A comparative analysis between two optical compensation methods, phase conjugation and amplitude modulation, has been carried out to test the visual improvements in retinal images in cataractous eyes.

Cataract is one of the common causes of visual impairment due to opacification of the crystalline lens. Increased intraocular scattering affects the vision of cataract patients by reducing the quality of the retinal image. In this study, an amplitude

Light diffraction by two ultrasonic waves of frequency ratio 1:2 is examined beyond the Raman-Nath diffraction regime. Measurements were taken of +/- 1 order diffracted light intensities for some Raman-Nath parameter values, as a function of the phas

In this paper, we report on sequential decreases in the amplitude of photoacoustic (PA) signals from nanosecond laser pulse irradiation of various samples. These samples include biological tissues, such as dental-enamel and chicken/turkey breast as w

We describe the phenomenon of a sudden decrease in the amplitude of photoacoustic signals arising from nanosecond laser pulse irradiation of biological samples, measured in vitro. Several dental enamel and chicken/turkey breast samples are examined.

In the paper theoretical bases are presented, as well as their experimental verification, concerning an idea of a new type acousto-optic light ellipticity modulator, based on light diffraction phenomenon by ultrasonic waves, within the so-called inte
