Abstract: In an optical system that includes a coherent light source and an optical waveguide, a pulse width used by the optical waveguide to project image frames on a display is changed on a frame-by-frame basis. By changing the pulse width for each image frame, the locations and characteristics of visible interference patterns on the display are changed for each successive image frame. Changing the interference patterns for each image frame may result in the interference patterns being less detectable to a viewer. The change in pulse width for each image frame may be fixed or dynamic, and may be made in response to interference patterns being detected on the display.

Abstract: Within a lens-tube main body, the light-shielding member is fixed to a second lens frame in a second portion opposite to a first portion in which an image forming panel is shifted from an optical axis with the optical axis positioned therebetween. Since the light-shielding member is fixed to the second lens frame in the second portion, heat caused by the unnecessary light is distributed from the first portion to the second portion within the light-shielding member. Accordingly, a local temperature rise is suppressed, and deformation of a lens-tube main body is suppressed. Accordingly, tilt of lenses due to deformation of the lenses does not occur, and deterioration in resolution of the entire image caused by the tilt of the lenses or the occurrence of focus position shift in a diagonal direction due to the occurrence of field curvature is suppressed.

Abstract: Methods and apparatus for automatically aligning a confocal aperture utilize a confocal imaging system and a computer controlled optimization algorithm such as the Nelder-Mead algorithm for imaging an in-vivo eye having chromatic aberration. When using a confocal aperture of 3.4 Airy disks in diameter, images were obtained using retinal radiant exposures of less than 2.44 J/cm2, which is ˜22 times below the current ANSI maximum permissible exposure. The embodied method can be used, e.g., to study RPE morphology in AMD and other diseases, providing a powerful tool for understanding disease pathogenesis and progression, and offering a new means to assess the efficacy of treatments designed to restore RPE health.
