ASE Optics Europe participates to DESDE i+d presenting its article “Digital NVIS with anamorphic optics”, where an anamorphic objective is designed to recover symmetry on FOV coverage for a NVIS digital system based on a CMOS sensor.
The current system has been designed to combine symmetrical and non-symmetrical lenses, based on free-form surfaces, to reduce complexity and cost of manufacturing.
The actual modeling of the non-spherical surfaces is presented, describing the use of free-form surfaces in the system to produce the non-symmetrical optical FOV, which matches the sensor’s aspect ratio. Manufacturing issues and image quality metrics are also discussed.
