Instead, a caesium iodide phosphor is deposited directly on the photocathode of the intensifier tube. The image intensifier is replaced by an "Alis" thermal imager. It is performed under ultrasound guidance, CT fluoroscopy or under image intensifier. These cameras consist of an image intensifier, CCD sensor and an integrated delay generator. Another type of reduplication occurs in Standard Finnish; reduplication as an intensifier. Optical feedback is also found in the image intensifier tube and its variants.

The MCP intensifier is similar technology used for night vision applications. Celtic and English have formal identity between intensifier and reflexive pronoun.
