Abstract
A method and device are disclosed for simulating a light source having a light intensity profile that varies in time. The method includes providing a light source; using a mask to at least partially block light emitted by the light source; and adjusting the position of the mask in accordance with an electrical signal representative of the light intensity profile so as to adjust the extent to which the mask blocks light from the light source, and thereby providing the light intensity profile that varies in time. The device can include a mask to at least partially block light from a light source; and an actuator for adjusting the position of the mask in accordance with the electrical signal.
