Optimizing for MTF Performance using Contrast Optimization

Our new Contrast Optimization technique allows for robust and efficient optimization on the system MTF at a given spatial frequency. The method minimizes the wavefront differences between pairs of rays separated by a pupil shift corresponding to the targeted spatial frequency, which maximizes the MTF. Further computational efficiency is achieved by using Gaussian Quadrature to determine the pattern of rays sampled. Examples are given to demonstrate the advantages of the technique.

Modeling Moiré Fringing Effects in OpticStudio Non-Sequential Mode

This article outlines the basic theory of Moiré patterns, and how fringing effects can arise in OpticStudio non-sequential models. The fringing effects of a pattern on a pixelated detector are demonstrated with a basic system in which a patterned slide is projected directly onto a detector, and a more complex system in which the slide is imaged through a lens. Sample files are provided.

How to debug a DLL or EXE

This article shows a technique to attach the Visual Studio debugger to a running process in the case of a user defined surface (DLL) and in the case of a user defined operand called UDOC (EXE). The technique is shown here using Microsoft Visual Studio Express 2013 Desktop.

Compile the DLL or EXE
Open OpticStudio and select the user defined surface or operand
Attach to Process
Set Breakpoints
Run the DLL/EXE
Stop the debugger
Distributing the DLL/EXE in Release Mode
