High Resolution Solar Imaging at 1.65 micro with a 64-Element Array

An imaging system using a 64-element array of PbS detectors has been successfully tested at Kitt Peak. The first images of the low contrast solar granulation at 1.65 micro have been obtained with a signal-to-noise ratio better than 200 and a resolution of the order of 1 see of arc. The problem of im...

Zusammenfassung:An imaging system using a 64-element array of PbS detectors has been successfully tested at Kitt Peak. The first images of the low contrast solar granulation at 1.65 micro have been obtained with a signal-to-noise ratio better than 200 and a resolution of the order of 1 see of arc. The problem of imaging systems for low contrast objects in the infrared is discussed.
