The present invention provides extended depth of field or focus to conventional Amplitude Contrast imaging systems. This is accomplished by including a Wavefront Coding mask in the system to apply phase variations to the wavefront transmitted by the Phase Object being imaged. The phase variations induced...http://www.google.fr/patents/US20020196980?utm_source=gb-gplus-shareBrevet US20020196980 - Combined wavefront coding and amplitude contrast imaging systems
