The quality of an optical surface depends on a number of factors, the most important of which is its surface topography. This paper is concerned with the problem of measuring and specifying the topographic finish of homogeneous, isotropic mirrors; an area of considerable practical interest.

Many benefits are derived from linking the design and manufacturing disciplines together. The benefits include reduced time to market, lower unit manufacturing cost and improved product quality. However, in most optical shops a wall still remains between design and manufacturing.

Surface relief holograms have intrinsic nonlinearity. A very important step in fuzzy analysis of HOE fabricating process is to choice parameters from procedure for making photoresist hologram. We select some parameters for the reason we can’t fix it or control it in a economic process, and some parameters for the sake of compensation.

There are many challenges associated with the design and construction of telescopes to have diffraction limited performance over the range from 400 to 900nm. The general applications of the system described are for television, film, and visual observation of objects from 300 meters to infinity with a 300mm aperture and focal lengths of 500, 1000, 2000, and 4000mm. The systems are designed to perform well at temperatures from -20 to 40 degrees Celsius and maintain high boresight stability when used as a tracking telescope. A sealed and purged instrument is essential for long term durability of the perforamnce. The figure shows the optical schematic of the system.

Magnetorheological (MR) fluids are multicomponent systems consisting of a non-colloidal magnetic-dispersed phase in a carrier liquid, which undergo rapid, sharp and reversible changes of their internal structure in an external magnetic field. As a consequence, their rheological properties, such as viscosity, plasticity and elasticity are controllably changed (for example, see Figure 1).

The AXAF observatory is the third of NASA's four planned "Great Observatories"1. It is designed to image cosmic x-rays in the energy regime of 0.1 to 10 keV (124 - 1.24 Å). The mirror assembly consists of four concentric, confocal, Wolter type I telescopes. Each telescope includes two conical grazing incidence mirrors, a paraboloid followed by a hyperboloid.

The dimpling technique is widely used to measure subsurface damage SSD. The ground surface is first acid etched to open up the fractures. A dimple is polished into the surface by a sphere of a known diameter, and the diameters of the circular zones with and without visible subsurface fractures are measured to determined the damage depth. The measuring system consists of a microscope with a reticule and a linear translation stage. The diameters of the various zones are visually interpreted and measured. The dimpling technique provides a direct measurement of SSD, as opposed to other techniques where the SSD is implied from other properties such as scattering. The manual measurements associated with this technique are tedious and requires a trained operator to identify the deepest fracture.

The processes of cutting, grinding and polishing optical materials cause fractures that extend some depth below the surface. The unrelieved strain and deep cracks present below the surface can seriously affect the performance of an optical system, especially in applications requiring precision optics. Subsurface damage (SSD) can lower image contrast, cause figure instability, and contribute to catastrophic fracture in high-power lasers [1]. Different optical materials present different forms of physical damage. Techniques used to increase productivity, such as high feed rates and high lap pressures, are the most serious causes of SSD [2]. An easily employed and non-destructive SSD measurement is important for the improvement of optical fabrication techniques.

Single point diamond turning is a cost effective method of making aspheric optics for use in the infrared. Because the technique leaves fine grooves or tool marks in the surface of the turned part, diamond turned aspherics are not generally suited for use in the visible spectral region without post polishing of the turned surface. If this polishing is not done the surface exhibits a rainbow-like scattering that is objectionable in the final optical system.
