Since artificial space objects are observable only in a short period of time and the characteristics of their motion is not exactly predictable, it is difficult to obtain both photometric and spectroscopic data by a set of observations. We have, ther

Several methods have been developed through the years to mount lenses with the ultimate goal of minimizing their positioning errors with respect to the nominal optical layout. This is a non-trivial task, since it requires either very well controlled

Optical payloads are hosted on a range of spacecraft and reach orbit on a variety of launch vehicles. Traditionally, each payload imposes specific requirements on the mounts such as surface figure, thermal environment, and first dynamic mode. The pro

Currently a number of manufacturers of opto-mechanical hardware offer mirror mounts that have features incorporated to reduce long term drift and reduce temperature induced mis-alignment. These designs tend to feature kinematic approaches and careful

We present a motorized optical mount based on a voice-coil actuator from an obsolete computer hard drive. Instead of using complex servo motors and motion sensors as the commercial motorized mounts, our homemade mount adopts a buffering circuit for m

Proximity exposure with line beam scanning can be an alternative to traditional proximity exposure for a fast, high-resolution, large-area patterning. The optical elements used for shaping the line beams have a very large length-to-cross-sectional ar

One of the most common pieces of opto-mechanical hardware is the one inch, tip-tilt, mirror mount. Though there are numerous manufacturers of these mounts the majority of the designs follow the familiar theme of a corner pivot point and two adjustabl
