The test system is composed of 6 different optics, illumination module, 2 different CCD cameras, a 1951 USAF resolution test target, fine positioning stages and the data processing software developed under MATLAB to calculate the image contrast at various spatial frequencies and to plot the MTF graphs. Results are presented using 8 different light sources for the 4 different lenses and their 6 different combinations: Rodenstock Apo Rodagon D 2x (Retro) with 1.6x extension tube, Sill Optics Correctal TL72/1.5 Telecentric Lens, Navitar Zoom 6000 motorized lens with 0.75x and none lens attachments and 2x-F mount zoom adapter, Navitar 12x Zoom lens with 0.5x and 0.75x lens attachments and 2x-F mount zoom adapter. </span> <em style="mso-bidi-font-style: normal;"> <span style="font-size: 12pt; mso-ansi-language: EN-US;" lang="EN-US"> <span style="mso-spacerun: yes;">  </span> </span> </em> </span> </p> <p class="MsoNormal" style="text-align: justify; margin: 0cm 46.2pt 0pt 36pt; mso-layout-grid-align: none; mso-pagination: none;"> <span style="font-size: 8pt; mso-no-proof: yes;" lang="EN-GB"> <span style="font-family: Times New Roman;">  </span> </span> </p> <p class="MsoNormal" style="text-align: justify; margin: 0cm 46.2pt 0pt 36pt; mso-layout-grid-align: none; mso-pagination: none;"> <span style="font-size: 8pt; mso-no-proof: yes;" lang="EN-GB"> <span style="font-family: Times New Roman;">  </span> </span> </p> <p class="MsoHeader" style="text-align: justify; line-height: 150%; margin: 0cm 0cm 6pt; tab-stops: 37.0pt center 8.0cm right 16.0cm;"> <span style="font-family: Times New Roman;"> <strong style="mso-bidi-font-weight: normal;"> <span style="line-height: 150%; font-size: 8pt;" lang="EN-GB"> <span style="mso-tab-count: 1;">                </span>Key Words </span> </strong> <span style="line-height: 150%; font-size: 8pt;" lang="EN-GB">: </span> <em> <span style="line-height: 150%; font-size: 8pt; mso-ansi-language: EN-US; mso-no-proof: yes;" lang="EN-US">MTF, Resolution, Bar Pattern, Contrast Transfer  </span> </em> </span> </p> <p class="MsoHeader" style="text-align: justify; line-height: 150%; margin: 0cm 0cm 6pt; tab-stops: 37.0pt center 8.0cm right 16.0cm;"> <span style="font-family: Times New Roman;"> <em> <span style="line-height: 150%; font-size: 8pt; mso-ansi-language: EN-US; mso-no-proof: yes;" lang="EN-US">                                    Function, 1951 USAF Resolution Test Target, </span> </em> </span> </p> <p class="MsoHeader" style="text-align: justify; line-height: 150%; margin: 0cm 0cm 6pt; tab-stops: 37.0pt center 8.0cm right 16.0cm;"> <em> <span style="line-height: 150%; font-size: 8pt; mso-ansi-language: EN-US; mso-no-proof: yes;" lang="EN-US"> <span style="font-family: Times New Roman;"> <span style="mso-tab-count: 1;">                                   </span>Image Quality </span> </span> </em> <em style="mso-bidi-font-style: normal;"> <span style="mso-ansi-language: EN-US;" lang="EN-US"> </span> </em> </p> <p>  </p>}, number={1}, publisher={Gazi University}
