Stereoscopic device including at least two apertures, each including a light valve, a multi wavelength light sensor array and a controllable multi wavelength illumination unit, producing at least two alternating beams of light, each of the beams of light is characterized as being in a different range of wavelengths, wherein each light valve is operative to open at a different predetermined timing and wherein the multi wavelength light sensor array detects a plurality of images, each of the images corresponding to a predetermined combination of an open state of a selected one of the light valves and a selected one of the modes.

Optical device

Stereoscopic device including a lenticular lens layer and light sensor array, the lenticular lens layer includes a plurality of lenticular elements, the sight sensor array includes a plurality of light sensors, wherein selected ones of the light sensors detect light at a predetermined range of wavelengths and wherein at least selected others of the light sensors detect light at at least another predetermined range of wavelengths and wherein each of the lenticular elements is located in front of a selected group of the light sensors, thereby directing light from different directions to different light sensors within the selected group of the light sensors.

A method of laser treatment of surfaces comprises the steps of: I) projecting onto the substrate surface laser pulses defining a beam; II) causing said beam and said surface to become relatively displaced in such a way that said beam will intersect at each number of pulses, preferably at each pulse, an area of said surface that is different from and non-adjacent to the area the beam intersected before said displacement; and III) continuing to cause that the beam and said surface to be treated so to become relatively displaced, until all of said strips have thus been treated by the laser beam.

Method and apparatus for the laser processing of substrate surfaces

An optical inspection system is presented, aimed at detecting defects on a substantially flat workpiece having an axis of symmetry. The workpiece is supported on a stage so as to be in an inspection plane, the stage being mounted for rotation in a plane parallel to the inspection plane. A scanning apparatus is accommodated above the workpiece, and comprises an illumination assembly, a plurality of optical assemblies, and a plurality of area sensors. The illumination assembly produces a plurality of incident radiation components for illuminating a strip on the workpiece extending parallel to the axis symmetry between two opposite sides thereof. The optical assemblies are aligned along the axis of symmetry in a spaced-apart parallel relationship, and are mounted for reciprocating movement within a plane parallel to an inspection area that covers substantially a half of the workpiece. The area sensors are arranged in a predetermined manner, each area sensor being associated with a corresponding one of the optical assemblies for receiving a component of returned radiation and generating data representative thereof. The half of the workpiece is strip-by-strip inspected, then the stage with the workpiece is rotated by 180&deg; and the other half of the workpiece is strip-by-strip inspected.

Optical inspection system and method

A device for extending the duration of a light pulse by a factor of an integer or by a factor which differs from an integer. The light pulse is passed through a device which divides the initial beam into a number of parts, where the first part passes unhindered while the subsequent parts of the beam are retarded and pass through the system after various delay periods, resulting in the desired extension of the pulse duration. The basic components of the novel device are spherical mirrors facing each other, a special reflector and a translation plate.
