SYSTEMS FOR AND METHODS OF FORMING MICRO-HOLES IN GLASS-BASED OBJECTS USING AN ANNULAR VORTEX LASER BEAM
The systems and methods disclosed herein utilize a beam-forming system configured to convert a Gaussian laser beam into an annular vortex laser beam having a relatively large depth of focus, which enables the processing of thick or stacked glass-based objects annular laser beam is defined in part by a topological charge m that defines an amount of rotation of the annular vortex beam around its central axis as it propagates annular vortex beam is used to form micro-holes in a glass-based object using either a one-step or a two-step method micro-holes formed by either process can be in the form of recesses or through-holes, depending on the application size of the micro-holes can be controlled by controlling the size of the annular vortex beam over the depth of focus range.
Device, system and methods for compensating for partial loss of visual field
A device (100) for compensating for part of the visual field comprises a wearable frame (110) configured to rest upon the face of a subject. An image capture device (120) is configured to capture an image from a first region (20) of the subject's visual field the first region being identified as a region of the visual field in which the subject's vision is impaired, and relay the image to an image display unit (130). The image display unit (130) is configured to project the image onto a region of the subject's retina that corresponds to a second region of the subject's visual field, in which the subject's vision is identified as non-impaired. Associated methods are also described.

WAVELENGTH CONVERSION ELEMENT AND PROJECTION DEVICE
A wavelength conversion element configured to receive an excitation light beam includes: a substrate configured to rotate about a central axis including a wavelength conversion region and a non-wavelength conversion region; and at least one wavelength conversion layer. When the substrate is rotated about the central axis, the non-wavelength conversion region and the wavelength conversion region alternately enter a transmission path of the excitation light beam. The substrate has a recessed portion located inside or outside of and surrounding the wavelength conversion region. The recessed portion includes an inclined surface. When the excitation light beam is incident on the inclined surface, the inclined surface reflects the excitation light beam to the wavelength conversion layer, and the wavelength conversion layer converts the excitation light beam into a converted beam. When the excitation light beam is incident on the non-wavelength conversion region, the non-wavelength conversion region reflects the excitation light beam.
