PARAS-2 precision radial velocimeter: optical and mechanical design of a fiber-fed high resolution spectrograph under vacuum and temperature control

Autor: Prasad J. S. S. V. Neelam, Rishikesh Sharma, Arpita Roy, Kapil Kumar, Abhijit Chakraborty, Nitesh Thapa

We present here the optical and mechanical design of a fiber-fed High-resolution spectrograph at resolution (R) = 100,000 which will be under vacuum (0.001 to 0.005 mbar) and temperature controlled environment at 25C ± 0.001C. The spectrograph will

Development of method for active alignment of multiple time delay and integration detectors in the optically butted focal plane assembly of high-resolution spaceborne imaging systems

Autor: B. Narasiha Sharma, Himanshu Dave, S. S. Sarkar, Anand Kumar, Manish Saxena, A. Sarkar, Nitesh Thapa

Publikováno v: Journal of Applied Remote Sensing. 12:1

Time delay and integration (TDI) detectors are preferred image sensors for high-resolution spaceborne imaging systems for cartographic applications as they provide higher sensitivity by integrating charges over multiple TDI stages in push broom mode.
