Abstract
The assembly (10) is a real-time imaging device for detecting radiation from an object field which is periodic in time. A video camera (14) detects emitted and reflected radiation from the object field (12) and produces a video signal comprising a series of pixels representing a frame of the image. The video signal is digitized (18) and received by a processor (16). The processor (16) averages the successive frames as in-phase images and quadrature images based on the periodicity of the object field to eliminate unsynchronous noise from the image and to display an image synchronous with the periodicity.
