Brief

This thesis focuses on the design and implementation of an automated scanning system for bandpass filter quality inspection using a miniaturized spectrometer and a 2D moving platform.

Summary

This thesis details the design and implementation of an automated system for bandpass filter quality inspection. It uses a miniature spectrometer to measure the transmission spectra of filters mounted on a 2D moving platform controlled by stepper motors. The system features custom software with algorithms for noise reduction and to automatically determine key quality parameters like peak wavelength, center wavelength, bandwidth, and cut-off depth, offering a fast and comprehensive alternative to existing methods.
