Dynamic Range Beyond Bit Depth of a CMOS Image Sensor Using Interleaved Row Readout
Supriyo Ghosh, William Martin, Hugh R. A. Jones +3
The dynamic range available from a sensor is vital to its utility. The limits on the dynamic range that can be obtained from an image sensor are set by the brightest and faintest o…
pyTANSPEC v1.0 and HxRGproc: Updated packages to Clean and Reduce TANSPEC data
Varghese Reji, Joe P. Ninan, Supriyo Ghosh +2
TIFR-ARIES Near-Infrared Spectrometer (TANSPEC) is a spectrograph-cum-imager operating over the wavelength range m. The instrument is mounted on the 3.6-m Devasthal O…
Use of solid fused silica etalon with broadband metallic coatings for calibration of high-resolution optical spectrograph
Supriyo Ghosh, William Martin, Kajal Kunverji +1
Wavelength calibration is a key factor for high-resolution spectroscopic measurements for precision radial velocities. Hollow-cathode lamps (e.g., ThAr), absorption cells (e.g., io…
Mitigating Modal Noise in Multimode Circular Fibres by Optical Agitation using a Galvanometer
Supriyo Ghosh, Chantira Boonsri, William Martin +6
Modal noise appears due to the non-uniform and unstable distribution of light intensity among the finite number of modes in multimode fibres. It is an important limiting factor in…
TANSPEC: TIFR-ARIES Near Infrared Spectrometer
Saurabh Sharma, Devendra K. Ojha, Arpan Ghosh +23
We present the design and performance of the TANSPEC, a medium-resolution m cryogenic spectrometer and imager, now in operation at the 3.6-m Devasthal Optical Telescope…
