https://dynamicstructures-optics.webs.com/apps/photos/ Active and Airborne Mirrors The "Y" scanner of a XY raster scanner. This part was donated to the Tucson, AZ Time Capsule Reducing inertia resulted in reduction in motor and power supply requirements, reducing the total cost of the scanning machine. Was used to digitize the Statue of Liberty and other large scale objects. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673180 197673180 These secondary mirrors provided a fast focus application with quicker response frequency and increased active stiffness. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673181 197673181 Designed to install in a suborbital rocket to study stars in the Ultra-Violet wavelengths. Two sides were designed to be removed after polishing to allow OTA support clearance in the rocket. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673182 197673182 Low mass allowed rapid focusing at 500Hz while having a mass of only 110gms. A voice coil could be used due to low mass and 3500Hz natural frequency. The ribs and face thickness are only 1.5mm thick. Sub-ribbing provided extra face support while keeping mass and inertia low. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673183 197673183 A back view of the 122mm primary showing extensive sub-ribbing. Mounting was through central hole. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673185 197673185 Interferogram showing a lack of print through or "quilting". https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673184 197673184 Used in adaptive optics applications. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673186 197673186 Allowed for adaptive optics application at 150Hz. Replaced a SiC mirror at 5% of cost. Used in a USAF telescope along with a series of matching Coude ellipses. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673187 197673187 Shows the highly convex face curve. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673188 197673188 Designed to reduce weight in an airborne application. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673189 197673189 Designed to reduce weight in an airborne application. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673190 197673190 An airborne Lidar telescope showing a simplified mounting because of stiffness, low mass requiring only three of the six integrated mounting sockets. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673193 197673193 One of 25 segments used to create an active primary array of 500mm for the NASA-PAMELA adaptive optics project. Note that the mirror is only 10mm thick with a curved face, a backplane 1.5mm ribs and mounting sockets and edge sockets for edge detection. Operating frequency is 1,000Hz. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673194 197673194 Face view of PAMELA primary segment. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673195 197673195 An adaptive optics demonstration test bed. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673192 197673192 Used at a grazing incidence for UV and X-ray applications. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673191 197673191 Low mass allowed for high speed video photography of projectiles. Low inertia and high stiffness permitted high acceleration and an optically stabile surface. 90 degrees of travel motion was completed in 0.1 seconds. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673196 197673196 A collection of scanning mirror shapes possible through molding of borosilicate glass. https://dynamicstructures-optics.webs.com/apps/photos/photo?photoID=197673197 197673197
