ABSTRACT:
An imager for the implementation of microscan comprises a member 18 for interrupting radiation between a lens and an array of imaging elements 13. The member 18 comprising alternate refractive transmissive regions 25 and non-transmissive regions 24. The transmissive regions 25 refracting radiation transmitted through them in the direction shown by the arrows. As the disc rotates across the array 13 the image focused on it moves giving successive frames which are shifted relative to one another.
