Abstract: Methods and systems for agricultural monitoring are disclosed. The methods and systems include: projecting, by a light source, a coherent light output on at least a part of a plant material; acquiring, by an imaging device, one or more speckle images based on the coherent light output backscattered by at least the part of the plant material; providing the one or more speckle images to a trained machine learning algorithm; identifying one or more healthy status indications of at least the part of the plant material based on one or more outputs from the trained machine learning algorithm, the one or more outputs corresponding to the one or more speckle images; and providing plant health information based on the healthy status indication. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methodology of phacoemulsification of a biological target such as a cataract with the use of a system including a laser diode configured to generate light in a millisecond pulsed regime and an optical fiber, while avoiding thermal diffusion of heat throughout the target. The used light has a wavelength within an absorption band of water and an average power within a milliwatt range; optionally, the output surface/facet of the optical fiber is curved and/or equipped with a termination configured to spatially converge output light upon propagating of such light through the termination.
