Holographic diffuser for future applications in astronomical instrumentation
Astronomical Telescopes + InstrumentationVolume Holographic Optical Elements (VHOEs) are specialized components that use recorded interference pat terns to shape light wavefronts and they could find applications in modern astronomical instruments where conventional optics cannot easily handle ...

Over half of the light incident on the Earth from the Universe falls within the Far-Infrared (FIR) region of the spectrum. Due to the deleterious effects of the Earth's atmosphere and instrument self-emission, astronomical measurements in the FIR require

All too often the instruments and instrument makers are totally ignored in accounts of historical science, but they, too, played a major role in the study of asteroids. “Throughout the eighteenth century, instrument making continued to provide a route to status as a natural philosopher for its most elite practitioners.

Ancient Astronomical Instruments
2015With the developments of ancient astronomy, ancient astronomical mechanical instruments were extensively used for measurements, computation, and demonstration. These instruments represented the combinational achievements of astronomy and mechanical engineering technology at the subjects’ eras.

Astronomical and Astrophysical Instruments
1991Great scientific advances are often bound up with the invention or introduction of new kinds of instruments. The telescope, the clock, the photographic plate, photometer, spectrograph and finally the entire arsenal of modern electronics each signalizes an epoch of astronomical investigation.

The Myth of Astronomical Instrumentalism
1991The central thesis of Paul Feyerabend’s paper “Realism and Instrumentalism” is that as well as general philosophical arguments for and against instrumentalism, there are specific scientific arguments in favor of the instrumentalist view. These scientific arguments have the following general form: a new theory realistically interpreted clashes with ...
