A Microscopic Hyperspectral-Based Centroid Wavelength Method for Measuring Two-Dimensional Junction Temperature Distribution of LEDs

In this letter, we propose an experimental method for determining two-dimensional (2D) junction temperature distribution of light-emitting diodes (LEDs) using microscopic hyperspectral-based centroid wavelength. The 2D centroid wavelength matrix is extracted from the hyperspectral data cube as tempe...
