Abstract
U laserskoj mikroskopiji, mikroskopski objekt je osvjetljen koherentnim laserskim svjetlom odred̄ene valne duljine. Optički sustav je zasnovan na Fresnelovoj optici, a rešetkaste strukture koriste se umjesto leće. Autori rada [1] za rekonstrukciju oblika promatranog objekta koriste informaciju o pomaku svjetlosti uzrokovanom prolaskom svjetlosti kroz objekt. Unutar ovog diplomskog rada, u simulacijski model razvijen u sustavu MATLAB, se nakon klasične optičke rešetke postavljaju mjerne rešetke sažimajućeg očitavanja. Iz mjerenja, čiji je broj znatno manji od Nyquistovog broja, rekonstruira se fazni gradijent objekta u visokoj rezoluciji, korištenjem l1-minimizacije.
Abstract (english)
In laser microscopy, a microscopic object is exposed to a coherent laser light of specific wavelength. The optic system is built on the principles of Fresnel optics, using the attenuating grid instead of lens. In [1] phase gradients in the sample modify the grid reference pattern and are used for the reconstruction of the observed object’s thickness. In this thesis, compressive sensing measurement masks are added to the simulation model developed in MATLAB environment. High resolution phase gradient is then reconstructed from a low number of measurements (much lower than the required Nyquist rate) using the l1-minimization algorithm.
