Solution Overview
Problem
The existing interference observation apparatuses face challenges in optical adjustment during assembly, leading to increased costs and complexity.
Innovation Solution
An interference optical apparatus is designed to be integrated between the objective lens attachment portion and the objective lens in a microscope, featuring a housing that holds key optical components, including beam splitters, a light source, photodetector, and a reference optical system with a mirror moving unit, allowing for easy optical adjustment and phase control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If individual components are prepared and assembled separately in existing interference observation apparatuses, then the apparatus can achieve interference imaging functionality, but the optical adjustment becomes difficult and costs increase
Solution Approach 1:
The patent integrates the light source, beam splitters, photodetector, and reference optical system into a single integrated interference optical apparatus that attaches between the objective lens attachment portion and the objective lens. This merging of previously separate components into one unified module enables easy optical adjustment while maintaining interference imaging functionality, directly resolving the technical contradiction between ease of manufacture and device complexity
2Reliability
If coherent laser light is used for feedback control in existing apparatuses, then phase lock can be achieved, but the system requires high-intensity illumination and becomes more expensive
Solution Approach 1:
The patent replaces expensive coherent laser light sources with inexpensive incoherent light sources (such as LEDs or halogen lamps) for the interference optical apparatus. The system achieves reliable phase lock and phase shift control using these lower-cost, lower-intensity incoherent light sources, thereby resolving the contradiction between phase lock accuracy and illumination intensity requirements while reducing overall system cost
