Technique for depth of field viewing of images using an aspherical lens

机译:使用非球面透镜观察图像景深的技术

摘要

A screen is disclosed for viewing depth of field images. The screen includes a prismatic screen mounted between a flat image and a viewer. Additional optical elements may be provided to enlarge a viewed image. A light hood may be provided to reduce glare and other effects of ambient light. Coating the screen with an anti-reflective coating may provide further protection from ambient light. Restructuring the image into smaller image elements provides image quality for a video image or the like. An aspherical lens may be used to minimize or remove distortion of the image perceived by a viewer to the side, above or below the center viewing axis of the screen. The present invention may find particular application in computer monitor systems, medical and obstetric imaging such as sonograms, musculo-skeletal imaging, vascular imaging, angiograms, angioplasty, dental probes, catheter probes, ear probes, endoscopy, laparoscopy, pelviscopy and arthroscopy.
