Patent number: 7477402Abstract: Determining surface topology of a portion (26) of a three-dimensional structure is provided. An array of incident light beams (36) passing through a focusing optics (42) and a probing face is shone on said portion. The focusing optics defines one or more focal planes forward the probing face in a position which can be changed (72) by the focusing optics. The beams generate illuminated spots (t2) on the structure and the intensity of returning light rays propagating in an optical path opposite to that of the incident light rays is measured (60) at various positions of the focal plane(s). By determining spot-specific positions yielding a maximum intensity of the returned light beams, data is generated which is representative of said topology.Type: GrantFiled: January 11, 2007Date of Patent: January 13, 2009Assignee: Cadent Ltd.Inventors: Noam Babayoff, Isaia Glaser-Inbari

Patent number: 6507441Abstract: A wide angle directed reflector is disclosed. The directed reflector includes a lenticular layer including at least one array of lenslets, each of which having a focal length, The directed reflector further includes a reflective layer which is disposed relative to the lenticular layer. The lenticular layer and the reflective layer are constructed, designed and relatively disposed such that light incident at an angle of incidence on the lenticular layer is reflected by the reflective layer and redirected through the lenticular layer at a substantially constant angle relative to the angle of incidence.Type: GrantFiled: October 16, 2000Date of Patent: January 14, 2003Assignee: Optid, Optical Identification Technologies Ltd.Inventors: Naftali P.

Patent number: 5764603Abstract: A system and a method for optical access of the surface of an optical disk (or another moving media information storage device) with a very short seek time is presented. The system uses two-dimensional deflection of a light (typically laser) beam. The beam reaches a stationary lenslet array, where, at a particular moment, it intercepts a single lenslet. The lenslet focuses the beam to a spot on the information storage surface of the disk. For reading information, the beam is reflected through the lenslet. Taking advantage of the "cat-eye" retro-reflection principle, only one detector (or very few detectors) is needed. Since only one spot at the surface is illuminated at any given moment, this spot gets most of the laser's light, allowing sufficient power concentration when needed for writing information on the disk.Type: GrantFiled: April 21, 1997Date of Patent: June 9, 1998Assignee: M.M.R.I.

Patent number: 4602843Abstract: An optically-generated or computer-generated holographic diffusing screen usable in bringing an image to focus thereon is a hologram which upon reconstruction displays a substantially transparent annulus on a substantially opaque background. The annulus preferably has an outer diameter substantially equal to the exit pupil of the image-forming lens, which image is to be focused. The radial width of the transparent annular portion is very small relative to the outer diameter of the annulus. The holographic diffusion screen may be formed by making a holographic image of the substantially annular pattern or by exposing a holographic plate with two collimated mutually coherent beams of light, one beam being perpendicular to the plate while the other is at an angle with respect to the first beam, rotating the holographic recording plate a predetermined amount, and repeating the exposing and rotating steps until a predetermined number of exposures has been completed.Type: GrantFiled: December 3, 1982Date of Patent: July 29, 1986Assignee: Yeda Research and Development Company, Ltd.Inventor: Isaia Glaser-Inbari
