Abstract

Image intensifiers are always used to amplify low light level (LLL) images in a wide wavelength range to observable levels. As a leader in image intensifiers for industrial and scientific applications, intensified CCD (ICCD) is an innovative product which is a hybrid of image intensifier and CCD. Over the past few decades ICCDs have been increasingly developed and widely used in a variety of fields such as LLL television system and medical diagnostics. In this paper, we present the application of ICCD in the field of LLL remote sensing. General LLL imaging devices are introduced briefly, and their advantages and disadvantages are compared. ICCD technology which includes fundamental, configuration and development, is expatiated on. The major parameters which incarnate the performance of the LLL remote sensing ICCD camera are analyzed in detail, such as signal noise ratio (SNR), dynamic range, spatial resolution, etc. An ICCD camera is designed, and an imaging experiment is made to validate the imaging ability of it in LLL condition. The experiment results are discussed and summarized. At last, the most important issues to the application of ICCD in LLL remote sensing are generalized in detail.
