Images obtained from image intensifier (II) tubes offer good insight into objects illuminated at low light levels. Since the dynamic range of II is very high, it is possible to construct high dynamic range images using information on the II tube gain when the screen image is recorded using a CMOS sensor. This paper presents a method for creating the best array of images for high dynamic range (HDR) image formation. In this method the microchannel plate screen current is measured to detect sudden HDR image appearance. A night vision module microcontroller commands CMOS camera exposure times during the steep change of microchannel plate gain. Test results demonstrate good quality images in high contrast environments.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
