Wavefront-coding is a technique in imaging systems that uses signal processing as an integral part of the image capture. In addition, wavefront-coded imaging uses phase elements that must be designed specifically for each application. This combinatio

Wavefront coding is a technique that combines optical phase elements and digital signal processing in order to increase the effective depth of focus of optical systems. The success of wavefront coding lies in the design of a suitable phase mask place

Jacoby Fourier polynomial shaped phase masks (JFPM) have been shown to be potentially effective for extending the depth of focus in wavefront coding technique. However, some characteristics have not been reported in detail. Here, we will show perform

Wavefront Coding is a technique using generalized aspheric optics and digital signal processing to greatly increase the depth of field of imaging systems. In this work we propose the use of Jacobi-Fourier shaped phase masks to produce sharp and clear

Wavefront coding is a hybrid optical-computational technique that makes use of a phase modulating element in conjunction with a deconvolution algorithm to extend the depth of focus of imaging systems. The phase mask codes the wave-front in such a way

Wavefront coding is a hybrid optical-digital technique proposed to increase the effective depth of focus of optical systems. The key to wavefront coding lies in the design of a suitable phase mask placed at the system's aperture to achieve the invari

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

Wavefront coding refers to the use of a phase modulating element in conjunction with deconvolution to extend the depth of focus of an imaging system. The coding element is an asymmetrical phase plate shape, for most applications in the form of a tref

Wavefront coding is a technique that makes use of aspheric phase masks and image processing to greatly increase the depth of focus and/or reduce the cost of imaging systems. The phase mask adds a controlled amount of aberrations to the optical system
