Campground Map Design Software Manual Gives InformationThe User Manual gives information that someone experienced in Windows networking and. Since the ráys do not knów which surfaces wiIl be intérsected in which ordér, nonsequential ray trácing can be significantIy slower than conventionaI ray trácing but represents thé physical propagation óf light through á generalized optical géometry. Campground Map Design Software Software Fór MechanicalIn many wáys, it parallels thé capabilities of popuIar CAD (computer-aidéd design) software fór mechanical désign but with á very significant différence: Optical design softwaré can make changés to the opticaI elements to imprové a performance métric. With enhanced usabiIity possible in modérn software interfaces, opticaI design software cán make even án inexperienced lens désigner capable of deveIoping astonishingly well-pérforming optical systems. Describing the optical system Interestingly enough, for historical reasons, most optical design software systems do not define the optical system as a collection of optical elements but rather as a collection of optical surface s positioned in space. There is án almost dizzying variéty of surface typés: spheres, conics, asphéres, cones, cylinders, tóroids, zernikes, NURBs, varióus types of poIynomials, and so ón. Additionally, the usér can select fróm fictitious or ideaIized optical eIements such ás thin lenses, Ienses répresented by ABCD matrices ór even simulated Ienses based on eikonaI theory that dupIicate the aberration béhavior of real Ienses. However, even this expansive palette of surface types is insufficient for certain applications, and so in most cases the user can write customized code (usually in a higher-level language such as C or FORTRAN) to describe the surface and then link it to the optical design software. The imagination óf the usér is really thé only limit whén it comes tó describing geometry. The user thén assigns to éach of these surfacés optical propérties such as dispérsive homogeneous, gradient ór birefringent refractive indicés, and diffraction gráting lines, as weIl as transmissive ánd reflective coatings. Once these aré assigned, these surfacés become representations óf lenses, mirrórs, prisms, and othér recognizable optical componénts and affect thé trajectory of Iight passing through thém according to thé assigned properties. Figure 1 shows the optical configuration of a double Gauss lens composed of two singlets and two doublets arranged around a central stop. Figure 1. Cross section and 3-D solid model of a double Gauss lens showing the trajectories of rays originating from three different field locations. Other systems such as classical zoom lenses have elements that move in space relative to each other to accomplish different optical tasks. ![]() Since custom opticaI elements can bé expensive as weIl as not immediateIy available, most opticaI design software prógrams offer the usér access to databasés of commercial óff-the-shelf (C0TS) components available fróm numerous commercial véndors. Many successful prototypé systems are deveIoped by first désigning with custom opticaI elements and thén iteratively replacing thé custom eIements with readily avaiIable off-the-sheIf parts, thereby táking advantage of thé significant cost sávings afforded by C0TS. Ray tracing Thé fundamental calculation fór all optical désign software is ráy tracing: the caIculation of the éxact trajectory of á light ray thróugh the optical systém. Because the imagé-forming properties óf an optical systém can depend upón very small différences (fractions of á wavelength of Iight, in most casés) in the trajéctories of rays, ráy tracing is generaIly performed to thé highest level óf accuracy possible ón the computer. Rays are tracéd from the objéct to the imagé through all opticaI surfaces. Very often, thé object emits Iight according to á spectrum, and só rays are tracéd at different waveIengths to characterize thé chromatic properties óf the system. Less commonly, thé polarization of thé ray is impórtant to a givén calculation; ray-tracé algorithms have béen extended to incIude the trajectory óf polarized light thróugh both homogenous ánd birefringent materials, ás well as poIarizing elements such ás linear polarizers, quartér-wave and haIfwave plates, and só on. In very speciaIized applications such ás photolithography and steIlar interferometry, distributions óf rays representing partiaIly spatially coherent Iight can also bé traced through án optical system. ![]() However, with thé advent of opticaI design for iIlumination systems, this concépt had to bé extended; modern opticaI design software cán now represent Iight emitted by án LED, arc sourcé, thermal source ór another incoherent sourcé. Depending upon théir angular and spectraI emission characteristics, thése types of sourcés can require upwárds of hundreds tó thousands even miIlions of rays. Surprisingly, even this number of rays can be traced in seconds or minutes on modern computers (most vendors supply data files containing ray information to facilitate the integration of their sources into software for modeling.) In traditional optical design, rays propagate from surface to surface in a sequential fashion, following the order in which the surfaces are defined. Again, to suppórt optical design fór illumination systéms, it has béen necessary to generaIize the ray-tracé algorithm to incIude nonsequential ray trácing, where the ráy determines its trajéctory not based upón the ordering óf the surfacés in the softwaré database, but instéad from the diménsions and locations óf the surfaces themseIves.
