Iconoscope is an outdated term used to describe a type of camera tube that was once widely used in the television industry. This tube was used to convert optical images into electrical signals that could be transmitted over the airwaves and received by televisions. While there may not be any direct synonyms for the term "iconoscope," there are related terms that can be used to describe similar technologies, such as the charge-coupled device (CCD) or the complementary metal-oxide-semiconductor (CMOS) sensor. These technologies have largely replaced the iconoscope in modern television and camera systems and offer superior image quality with fewer drawbacks.
