ABSTRACT:
A photoemission apparatus includes a spatial light modulator (2) and an integral photoemitter (5). A lens array (1) focuses light through the spatial light modulator (2) onto the photoemitter. Electrons emitted by the photoemitter (5) are deflected electrostatically by electrodes (10) and are accelerated through a screening mesh (8) onto a phosphor screen (6). Light emitted by the screen (6) passes through a further lens array (7).
