プロジェクタ。Light from a light source is transmitted through the film on which the image is drawn, and this transmitted light is reflected by a reflecting mirror installed on the optical axis of the light source at an appropriate angle to the optical axis, thereby displaying the image on the screen. In an over-the-radar projector that projects an enlarged image, the above-mentioned reflecting mirror is a half mirror, and this half mirror
A condensing lens is provided behind the half mirror to condense the transmitted light from the half mirror to a predetermined distance on the optical axis of the light source, and an imaging device is provided at the convergence point of the transmitted light by the condensing lens, and An over-the-radar projector characterized in that the image sensor is connected to a transmission line for transmitting the video signal to another location.
