Abstract
Infrared (IR) light can be utilized in important applications ranging from the military to the medical field. To detect this IR light, IR cameras can be used. Issues arise when these IR cameras need to be calibrated using natural IR sources. These IR sources are insufficient to calibrate IR cameras due to the cost and their low range of light intensities. Therefore, IRSP technology was developed to overcome this challenge. To further improve on IRSP technology, a super-latticed light emitting diode system (SLEDS) was created. SLEDS projector technology displays IR images at greater apparent temperatures, is capable of projecting images with better resolutions, and can project at higher framerates. ☐ The light output produced for each pixel in the SLEDS projector is captured by an IR camera and this data can then be analyzed to further improve the system. To analyze this data efficiently, the NUD analyzing toolkit (NAT) was developed. NAT has a multitude of data analysis tools used to analyze the light output for each pixel in the projector. The tools can be configured by the user to meet their demands. With these tools, the user can observe a single set or multiple sets of light outputs for all pixels in the projector. Through NAT and its features, the discoveries made by analyzing this data can help to improve the SLEDs system.
