Abstract: Disclosed herein is a method including: providing a light guiding arrangement (LGA) configured to redirect light, incident thereon in a direction perpendicular to an external surface of the sample, into or onto the sample, such that light impinges on an internal facet of the sample nominally normally thereto; generating a first incident light beam (LB), directed at the external surface normally thereto, and a second incident LB, parallel to the first incident LB and directed at the LGA; obtaining a first returned LB by reflection of the first incident LB off the external surface, and a second returned LB by redirection by the LGA of the second incident LB into or onto the sample, reflection thereof off the internal facet, and inverse redirection by the LGA; measuring an angular deviation between the returned LBs and deducing therefrom an actual inclination angle of the internal facet relative to the external surface.

Abstract: Disclosed herein is a system for producing a composite prism having a plurality of planar external surfaces by aligning and bonding two or more prism components along bonding surfaces thereof, the system includes: an infrastructure configured to bring the bonding surfaces of the first prism component and the second prism component into close proximity or contact; a controllably rotatable mechanical axis configured to align at least one first surface of the first prism component and at least one second surface of the second prism component; a light source configured to project at least one collimated incident light beam on the at least one first surface and the at least one second surface; one or more detectors configured to sense light beams reflected from the first and second surfaces; a computational module configured to determining an average actual relative orientation between the at least one first surface and the at least one second surface based on the sensed data and if a difference between the weighted average actual relative orientation and an intended relative orientation between the at least one first surface and the at least one second surface is below an accuracy threshold, determine a correction angle for the controllably rotatable mechanical axis, wherein one or more of the prism components are transparent or semi-transparent.

CPC classification number: G01B11/26
Abstract: Disclosed herein is an optical-based method for validating angles between external, flat surfaces of samples. The method includes: (i) providing a sample including an external, flat first surface and an external, flat second surface nominally inclined at a nominal angle relative to the first surface; (ii) generating a first incident light beam (LB), directed at the first surface, and a second incident LB parallel to the first incident LB; (iii) obtaining a first returned LB by reflection of the first incident LB off the first surface; (iv) obtaining a second returned LB by folding the second incident LB at the nominal angle, reflecting the folded LB off the second surface, and folding the reflected LB at the nominal angle; (v) measuring a first angular deviation between the returned LBs; and (vi) deducing an actual inclination angle between the first second surfaces, based at least on the measured first angular deviation.
