Optical Component Mounting via Substrate Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting optical components, such as prisms, on substrates face challenges when one surface of the optical component does not transmit light, making it difficult to recognize positioning marks from the opposite surface, which hinders accurate alignment and mounting.
Innovation Solution
A mounting apparatus and method that includes a substrate, an optical component with adjustable positioning, an imaging unit in the optical path to capture image data, and a control unit to adjust the positions of the substrate and optical component relative to each other, ensuring accurate alignment and mounting by recognizing alignment marks and the outline of the optical component's surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an optical component with a non-transmissive surface is mounted on a substrate, then the optical component can perform its light-refracting function, but positioning marks on the optical component and substrate cannot be recognized from the opposite surface
Solution Approach 1:
Instead of observing positioning marks from the traditional opposite surface of the optical component, the patent inverts the observation approach by imaging through the substrate from below. The imaging unit captures images of positioning marks on both the substrate and optical component through the transparent substrate, enabling mark recognition despite the non-transmissive surface of the optical component.
2Manufacturing precision
If positioning marks are recognized from the opposite surface of the optical component, then alignment can be achieved, but this method fails when the surface does not transmit light
Solution Approach 1:
The patent introduces the substrate as an intermediary medium for imaging. Since the substrate is transparent, it serves as a mediator that allows the imaging unit to capture images of positioning marks on the optical component from below, bypassing the problem of the non-transmissive surface of the optical component.
3Difficulty of detecting and measuring
If complex imaging configurations are used to overcome non-transmissive surfaces, then positioning marks can be recognized, but the system becomes more complex and costly
Solution Approach 1:
The patent extracts and utilizes the existing transparent substrate as the imaging window, eliminating the need for additional complex imaging systems. By using the substrate itself as the transparent medium for imaging, the solution avoids adding extra lenses, windows, or complex optical paths that would increase system complexity and cost.

Function Achieved in This Case
Enables accurate alignment and mounting of optical components by capturing image data and controlling the relative positions, overcoming the limitations of non-transmissive surfaces and ensuring precise alignment without complex configurations, thus facilitating low-cost, efficient mounting processes.
Implementation Method 1

AI summary
A mounting apparatus includes a substrate; an optical component having a first surface on which light from the substrate is incident and a second surface from which the incident light goes out after the incident light is refracted; an adjustment unit that adjusts a position of the substrate and a position of the optical component by moving the substrate and the optical component relatively with the first surface of the optical component and the substrate being opposed to each other; an imaging unit that is arranged in an optical path of the light that goes out from the second surface; and a control unit that controls an amount by which the adjustment unit moves the substrate and the optical component relatively according to image data which is captured by the imaging unit, and that mounts the optical component on the substrate.
