26 Oct 2006 CODE V 9.7 Delivers Fast, Accurate Visualizations of Optical System Performance A new image simulation feature in CODE V® 9.7 from Optical Research Associates (ORA®) makes it easier for optical system designers to visualize overall performance and to communicate design tradeoffs to non-optical personnel. Specifically, the new 2D Image Simulation function models how an object would appear when imaged by the optical system, taking into account diffraction, lens aberrations, distortion, relative illumination, and even blurring due to detector pixel size. This function also determines image orientation for complex folded systems. Using the power of the Fast Fourier Transform (FFT) calculation, 2D Image Simulation delivers much more efficient and accurate results than geometrical ray-blasting techniques. To use 2D Image Simulation, an original “object” is simply presented to the software as a BMP format image file, and the calculated “image” is then displayed. Results can then be saved in BMP, JPEG, and PNG formats.
CODE V 9.7 also offers expanded functionality in several other areas. For example, an enhanced 1D Partial Coherence function facilitates the design of microlithography optics, and other systems that rely on partial coherence. And the addition of a Gaussian Quadrature Radial Grid for defining ray sets speeds optimization of systems having circular or vignetted circular pupils. The software also features an expanded array of performance metrics and plots for quantifying optical system performance.
With over 40 years of success as an industry leader, Optical Research Associates (ORA) is committed to delivering innovative solutions to the optics industry. With its CODE V and LightTools® software products, ORA is the world’s leading developer of optical software. ORA is also the largest independent supplier of optical design and engineering services, with more than 4,000 completed projects since the Company was founded in 1963.
