An essential goal for physics and optical science instructors is to encourage students to find excitement and beauty in physical and optical phenomena while helping them learn the theoretical concepts and conducting experiments that can test the vali

We propose a direct two-dimensional Fourier domain fitting-free method to determine the period of a Ronchi ruling. A precise method to measure a spatial frequency target’s quality and fidelity is highly desired as the pattern period directly affect

We investigated the geometrical characteristics of off-axis parabolic mirrors (OPMs). We found that the clear aperture of an OPM is an ellipse with a set of major/minor diameters, and the center of the elliptical aperture does not correspond to the d

An alternative description for the Gaussian image plane (GIP) of an optical system for a given object is presented, which applies to both aberration-free and non-aberration-free systems. We extend the definition of transverse magnification (TM) to th

(Received January 19, 2015 : revised February 10, 2015 : accepted February 10, 2015)A simple method to determine the focal length of a lens using the Talbot image is presented. This method uses only one grating, requiring neither Moire fringe analysi

We investigated the geometrical characteristics of circular-aperture off-axis parabolic (OAP) mirror segments to clarify the meaning of the loosely defined word “center” used in the literature and in documents to describe OAPs. We proposed the el

A method to determine the transverse magnification (TM) of an imaging system is discussed. This method is different in that TM can be determined accurately by using distortion analysis. We demonstrate the validity of the method via numerical simulati
