IMAGING SYSTEM WITH WAVEFRONT MODIFICATION AND METHOD OF INCREASING THE DEPTH OF FIELD OF AN IMAGING SYSTEM

摘要

an imaging system (10) includes a lens (1), an image sensor (2).in a plan of image of the target.a calculation unit (3) intended to perform a numerical treatment ofthe image captured by the sensor. the objective is adjusted tomodifying a wavefront of radiation entering the system.a light detector such that the output isa radiation source is constant for a wide range ofvariation of distance from the source bycompared to the goal. the depth of field of the system is increased.the calculation unit may be simplified by using aa filter constant. the change of the wave profile is created byis invariant in any rotation around the axisview of the target.
