| Abstract: | The IGO telescope, equipped with the IFOSC (IUCAA Faint Object Spectrograph & Camera) instrument, is a back-end instrument for astronomical observations at optical wavelengths. The IFOSC supports imaging, spectroscopy, and polarization studies, and it includes additional systems such as a calibration unit, CCD Dewar and camera, a Common Control Unit (CCU), and control software.
This paper examines how these components are designed and how they improve the telescope's ability to observe. Integrating these systems provides a comprehensive view of advanced instrument design for astronomical purposes.
Key challenges in testing these systems and the methods used to ensure reliable calibration and accurate data capture are addressed. A discussion on the current specifications of the CCD controller, which uses analog CDS (Correlated Double Sampling) technology and receives astronomical data through fiber optic connectors, highlights hardware issues.
These issues, particularly data transmission and performance consistency, present significant difficulties, necessitating careful troubleshooting and innovative solutions. As technological advances continue, the need for instrument upgrades becomes essential. This paper highlights the contributions of IDSAC (IUCAA Digital Sampler Array Controller) hardware and software, which are crucial in enhancing instrument performance and data accuracy.
The new controller features increased clock speeds, three gain settings, and Ethernet-based data transmission, improving image quality and observational efficiency. This study provides valuable insights into the design, testing, and optimization of advanced astronomical instruments, establishing a framework for future enhancements in telescope instrumentation.
