Solution Overview
Problem
Conventional interferometers face limitations in producing interference patterns efficiently without the need for beam splitters or complex alignment, particularly in applications requiring precise control over light paths and interference patterns.
Innovation Solution
An interferometer design utilizing a glass disc with a frosted surface, where a laser source projects a beam that produces both refracted and reflected beams, with the refracted beam being reflected back to combine with the reflected beam to form an interference pattern on a target, utilizing a sensor and amplifier to process and enhance the signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional interferometers use beam splitters and complex alignment components, then interference patterns can be produced, but device complexity and vibration increase
Solution Approach 1:
The patent removes the beam splitter component from the interferometer system entirely. Instead of using a beam splitter to divide the light path, the invention uses a simple mirror to reflect the laser beam, eliminating the need for complex beam splitter alignment while still producing the necessary reference and sample beams for interference pattern generation
Solution Approach 2:
The patent inverts the conventional approach by using reflection instead of refraction through a beam splitter. The mirror reflects the laser beam to create the reference path, while the sample beam passes through the test object, reversing the typical beam splitting methodology and simplifying the overall system architecture
2Manufacturing precision
If conventional interferometers use multiple optical components, then light paths can be controlled, but device vibration and noise increase
Solution Approach 1:
The patent removes unnecessary optical components from the system. By using a simple mirror instead of a beam splitter and eliminating complex alignment mechanisms, the invention reduces the number of moving parts and potential vibration sources while maintaining precise light path control through the simplified optical arrangement
Solution Approach 2:
The patent combines the functions of multiple components into a single mirror element. The mirror simultaneously serves to create the reference beam, define the light path, and eliminate the need for separate beam splitter and alignment components, thereby reducing vibration and noise while maintaining control precision
3Reliability
If conventional interferometers use complex alignment mechanisms, then interference patterns can be formed, but signal intensity and clarity decrease due to vibration
Solution Approach 1:
The patent eliminates complex alignment mechanisms and replaces them with a simple mirror-based system. This reduction in mechanical complexity minimizes vibration that would otherwise degrade signal clarity, while the stable reflected beam path ensures consistent interference pattern formation with higher signal intensity
