Cathode ray tube head-mounted display

A cathode ray tube head-mounted display (CRT HMD) is a type of head-mounted display that generates its visual content with cathode ray tubes (CRTs). This was the first type of head-mounted display and virtual reality headset.

This type of HMD was used in military equipment, such as equipment from Kaiser.

One company that sells CRTs for HMDs is Thomas Electronics.

CRTs have been made as small as 1 or 2 inches, or even smaller. They have been made as small as 3mm diameter. A small CRT can be magnified with optics.
