The Infrared Imaging Spectrograph (iris) for Tmt: Simulation of the Atmospheric Dispersion Corrector Using Idl
نویسنده
چکیده
IRIS (InfraRed Imaging Spectrograph) is a first light instrument presently being developed for the Thirty Meter Telescope (TMT). IRIS will include an integral field spectrograph and an imaging camera, covering wavelengths from 0.84 μm to 2.4 μm (infrared range). IRIS will work with the Narrow-Field Infrared Adaptive Optics System (NFIRAOS), achieving an unprecedented angular resolution [1], creating the sharpest images ever taken in the infrared.

The Infrared Imaging Spectrograph (IRIS) for TMT: the ADC optical design
We present the current optical design for the IRIS Atmospheric Dispersion Corrector (ADC). The ADC is designed for residual dispersions less than ~1 mas across a given passband at elevations of 25 degrees. Since the last report, the area of the IRIS Imager has increased by a factor of four, and the pupil size has increased from 75 to 90mm, both of which contribute to challenges with the design....

A computer program was developed to predict the dispersion of gas pollutant in the atmosphere. This program relies on puff method, and in order to consider the wind shear effects, the program has the ability to consider the complete dynamic and unsteady atmospheric conditions. Plume rise of hot pollutants due to buoyancy effects was also considered. The program has the capacity to perform the r...

متن کاملAtmospheric dispersion compensation for extremely large telescopes.
Achieving diffraction limited imaging with future ground-based optical telescopes will require adaptive optics for correction of atmospheric turbulence and also efficient techniques for atmospheric dispersion compensation. We study the benefit of using a linear atmospheric dispersion corrector (ADC) coupled with a deformable mirror on a 42-m Extremely Large Telescope (ELT) operating in the VIRJ...
متن کامل2. DESCRIPTION OF THE SPECTROGRAPH, STEP BY STEP 2.1 The ISB and optical component situated before the fore-optics The fore-optics of the present instrument will be installed on a side of the optical Instrument
The fore-optics of the present instrument will be installed on a side of the optical Instrument Selector Box. Inside the ISB, a moveable pick-off mirror deviates the light towards the foreoptics, at 90 from the beam coming from M3. When the mirror is off, the light enters the High Throughput Spectrograph, in construction at UNC. An ADC (Atmospheric Dispersion Corrector) and a Calibration Lamps ...
