{"product_id":"9781628415476","title":"Field Guide to Linear Systems in Optics","description":"\"Linear systems\" is a broad and important area in many scientific and engineering disciplines, and it is especially important in optics because it forms the basis for Fourier optics, diffraction theory, image-quality assessment, and many other areas. This Field Guide provides the practicing optical engineer with a reference for the basic concepts and techniques of linear systems, including Fourier series, continuous and discrete Fourier transforms, convolution, sampling and aliasing, and MTF\/PSF using the language, notation, and applications from optics, imaging, and diffraction.","brand":"SPIE Press","offers":[{"title":"Default Title","offer_id":47061812642032,"sku":"9781628415476","price":42.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781628415476_p0.jpg?v=1763868956","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781628415476","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
