We evaluate a novel wavefront sensing technique using digital holography. This technique divides the aperture plane into multiple subapertures with a unique digital holographic image created in each subaperture. This reduces the complexity and allows

Wavefront coding is an optical-digital technique that consists in introducing a suitable phase mask in the aperture plane able to extent, after image processing, the depth of field of an optical system. The key to wavefront coding lies in the shape o
