Upsampling

Upsampling

Managing signal sampling rates is essential in digital signal processing to maintain signal integrity. A decimated signal, characterized by a reduced frequency range due to its lower sampling rate, can be upsampled by inserting zeros between each sample. This upsampling process expands the original spectrum and introduces repeated spectral replicas at intervals dictated by the new Nyquist frequency. To refine this zero-inserted sequence, it is passed through a lowpass filter with a cutoff...

Summary

This summary is machine-generated.

A new multi-step overlap polishing path effectively reduces mid-spatial frequency (MSF) error in optical component manufacturing. This method significantly lowers peak power spectral density (PSD), improving surface quality compared to traditional raster paths.

Background:

Bonnet polishing is crucial for optical component fabrication, offering high efficiency and surface control.
Conventional raster polishing paths often introduce undesirable mid-spatial frequency (MSF) error.
Understanding the tool influence function (TIF) and feed direction is key to mitigating MSF error.

Purpose of the Study:

To investigate the influence of TIF and azimuthal feed angle on MSF error.
To develop and validate a novel multi-step overlap path strategy for MSF error reduction.
To enhance surface quality in optical component manufacturing.

Main Methods:

Numerical simulations to validate the proposed multi-step overlap path strategy.
Experimental polishing using the developed path strategy.
Analysis of peak power spectral density (PSD) to quantify MSF error reduction.

Main Results:

The multi-step overlap path significantly reduced peak PSD from 1160.44 nm²·mm to 235.6 nm²·mm.
Experimental validation confirmed the effectiveness of the proposed path strategy.
Demonstrated remarkable suppression of MSF error in bonnet polishing.

Conclusions:

Optimizing the azimuthal feed angle is critical for reducing MSF error.
The multi-step overlap path strategy offers an effective solution for minimizing MSF error.
This approach enhances the precision and quality of manufactured optical components.
