Projects

“ Design of Diffractive Optical Element using Digital Holography Techniques and Spatial Light Modulator” Tubitak, 2008-2010.
The design of a difractive optic element (DOE) which will provide a diffracted target optical field distribution by only changing the phase of optic field distribution sheding on it is achieved; the phase of the DOE structure is calculated with computer genereted hologram (CGH) technique called as 3- dimensional (3D) Gerchberg-Saxton (GS) algorithm. The targeted field distribution is obtained both optically (by means of spatial light modulator, SLM) and numerically by using this calculated phase.
A digital amplitude hologram of a 3D diffuse object is recorded on to CCD using a Fourier holography setup. The 3D object field is reconstructed both numerically and optically using the phase only information of this digital hologram that is calculated with Continuous Wavelet Transform (CWT) and Stockwell Transform (ST) algorithms
