1Productivity
If high volume assembly processes are used for manufacturing, then production efficiency and cost are improved, but positional accuracy and alignment precision of signal-processing components deteriorate
Solution Approach 1:
The patent implements adjustable positioners that allow signal-processing components to be dynamically repositioned after assembly. This enables the system to transition from static manufacturing positioning to dynamic optimization, where components can be adjusted to their precise operational positions despite variations introduced during high-volume assembly processes.
Solution Approach 2:
The patent changes the positional parameters of signal-processing components by introducing adjustable positioners that modify the location and orientation of components like signal sources and detectors. This allows the system to compensate for manufacturing tolerances and achieve optimal signal processing performance despite variations in assembly precision.

3Device complexity
If component positions are not adjusted, then device complexity is reduced, but signal amplitude and signal-to-noise ratio deteriorate
Solution Approach 1:
The patent segments the sensor system into adjustable modular components, each with its own positioner. This allows independent optimization of signal source, detector, and other components without redesigning the entire system, achieving high signal quality through modular adjustment rather than complex integrated design.
Solution Approach 2:
The patent implements self-adjustment mechanisms where the system can automatically optimize component positions based on signal quality feedback. This self-service capability achieves high signal amplitude and SNR without requiring complex external adjustment systems, as the system autonomously optimizes its own performance.

AI summary
An integrated sensor includes a sensor cell, a signal source, an input optical rotator, and a signal detector. The integrated sensor includes a positioner for a signal-processing component. The positioner may be a linear positioner for the signal-processing component, such as a signal source or a signal detector, or may be a rotational positioner for the signal-processing component, such as a polarizer or a polarized signal source. The signal-processing component is located on a signal path of the integrated sensor. A method of adjusting a linear position or rotational position of a signal-processing component is also disclosed. A linear position or a rotational position of the signal-processing component may be adjusted to improve performance of the integrated sensor.
