WebThis paper reports on the design, construction, and implementation of a new chopping secondary mirror system for the Kuiper Airborne Observatory. This observatory facility … WebThe new telescope features a chopping secondary and 2 Nasmyth ports. The excellent atmospheric transmission during winter time at the telescope site, Gornergrat near Zermatt, Switzerland, allow us flexible operation up to the highest atmospheric submm windows. We present the current status of the new telescope, in particular with regard to its ...

Chopping Secondary Mirror For The ESO 3.6m Telescope

In electronics, a chopper circuit is any of numerous types of electronic switching devices and circuits used in power control and signal applications. A chopper is a device that converts fixed DC input to a variable DC output voltage directly. Essentially, a chopper is an electronic switch that is used to … See more Chopper circuits are used in multiple applications, including: • Switched mode power supplies, including DC to DC converters. • Speed controllers for DC motors See more For all the chopper configurations operating from a fixed DC input voltage, the average value of the output voltage is controlled by periodic opening and closing of the switches … See more Take a general step-up chopper with voltage source $${\displaystyle V_{s}}$$ which is in series with the inductor $${\displaystyle L}$$, … See more One classic use for a chopper circuit and where the term is still in use is in chopper amplifiers. These are DC amplifiers. Some types of signals that need amplifying can be so small that an … See more • Braking chopper • Vibrator (electronic) See more • C. Enz, G. Temes, Circuit techniques for reducing the Effect of Op-Amp Imperfections: Autozeroing, Correlated Double Sampling and Chopper Stabilization - … See more WebThe secondary mirror is designed to chop at amplitudes of up to ± 5 arcmin at a frequency ≤ 10 Hz and up to ± 10 arcmin at a rate of ≤ 2 Hz. The visible beam is fed into the Focal Plane Imager (FPI+), which is an optical focal plane guiding camera. ckg legal perth
