A Wide Angle TV Camera Pickup Lens System Using Reflective Optics

摘要

The low transmittance of the wide angle optical probe, in use by NTDC, due to aging of the cement and small aperature, prevented full utilization of the novel TV system. The report documents the development of an optical probe for use as a replacement on an in-house CCTV system, based on an extension of work previously reported in the literature. Experimental effort to extend the field of view was performed. Based on data taken on the completed system an aperature was recommended for operation. (Author)
