    Abstract: A life-assisting system to enhance the quality of life for people with visual impairment. The system integrates state-of-the-art sensing and sensory stimulation with light detection and ranging (LiDAR), machine learning, and advanced haptic navigation to provide the visually impaired population with a real-time haptic map of the three-dimensional environment and auditory descriptions of objects within that environment. By allowing the visually impaired population to sense objects in the surrounding environment through haptic and auditory feedback, the disclosed system has the potential to promote individual independence, reduce anxiety and stress, facilitate access to educational and employment opportunities, and reduce social and economic gaps. To provide those benefits, the system uses multi-modal learning to convert higher dimensional (e.g., four-dimensional) scene data into lower dimensional (e.g., one-dimensional) auditory data and (e.g., two- or three-dimensional) haptic data.

    Abstract: The described methods and devices minimize or reduce the effects of the leading amplified spontaneous emission component of an optical pulse in optical multi-pass amplifier systems. One multi-pass optical amplifier includes a gain medium positioned to receive a pump laser, and to receive an optical pulse having a main component and one or both of a leading or a trailing component. The optical amplifier also includes one or more reflectors positioned at a first side or at a second side of the gain medium that allow multi-pass propagation of the optical pulse through the gain medium. The one or more reflectors are positioned to allow the main component of the optical pulse to traverse through the gain medium in a first pass before the leading component of the optical pulse reaches the gain medium in a second pass through the gain medium.
