摘要:
Techniques are discussed for correcting optical aberrations that exist in surveillance domes that have spherical and non-spherical parts. For example, the image quality of a surveillance camera is reduced when it focuses on an object through a non-spherical base of a surveillance dome. This image quality reduction could potentially compromise the security of the area monitored by the surveillance camera by failing to provide enough detail to identify individuals or other objects of interest. Utilizing a corrective optical element to provide curvature to a wavefront that travels through the non-spherical base, however, helps preserve the image quality of the camera and thereby helps maintain the integrity of the surveillance system.
