IR Spectrometers

IR Spectrometers

There are two main infrared (IR) spectrophotometers: dispersive IR spectrometers and Fourier transform infrared (FTIR) spectrometers. In a dispersive IR spectrometer, a beam of infrared radiation produced by a hot wire is divided into two parallel equal-intensity beams using mirrors. One beam passes through the sample, while another is a reference beam. The beams then move through the monochromator, which separates the radiations into a continuous spectrum of different frequencies. The...

Infrared (IR) Spectroscopy: Overview

Infrared (IR) Spectroscopy: Overview

When electromagnetic radiation passes through a material, atoms or molecules transition from a lower to a higher energy state by absorbing radiation corresponding to the energy difference between the two states. The absorption of infrared (IR) radiation causes transitions between vibrational energy levels in a molecule. Therefore, IR spectroscopy is a useful analytical tool for determining the molecular structure of molecules.
Different compounds display unique properties due to their...

Background:

Infrared mosaic arrays enhance detection resolution in aerospace.
Evaluating inter-chip uniformity is crucial for optimal performance.
Existing methods may lack accuracy or robustness.

Purpose of the Study:

To propose a robust and accurate method for evaluating inter-chip uniformity in infrared mosaic arrays.
To leverage human visual perception as a benchmark for uniformity assessment.
To develop a model that guides stitching and non-uniformity correction.

Main Methods:

Selected three key metrics: neighborhood difference (ND), Laplacian response (LR), and local standard deviation (LSTD).
Fused these metrics using a support vector regression (SVR) model.
Employed leave-one-out cross-validation (LOOCV) for generalization assessment.

Main Results:

The proposed method demonstrated satisfactory generalization on unseen configurations.
An ablation study confirmed the complementary nature and stable performance of the selected metrics.
Validation on independent datasets confirmed the method's robustness.

Conclusions:

The developed evaluation method accurately characterizes inter-chip uniformity in infrared mosaic arrays.
This technique can guide the selection of stitching sequences and assess non-uniformity correction.
The approach offers a reliable tool for improving infrared imaging systems.
