Suraj Haldar

1. Development of micro-thermal measurement unit for to determine atmospheric turbulence in Hanley, Ladakh. 2. My job is to design the sensors, backend electronics and analyze the results to determine the mentioned parameters. 3. A 16 bit, dsPIC 33 microcontroller will be used to control each stage after amplification, signal processing and adc conversion. A master module containing Raspberry Pi will be used to control all the PIC controllers in each stage and for data acquisition.

1. Develop micro thermal measuring sensors and backend electronics for turbulence measurement in Hanley, Ladakh, India. 2. Analyse the results obtained from the instrument and determine atmospheric seeing (r0) at the site. 2. Along with the above mentioned activity, coordinating with industries, track progress, obtain scheduled deliverables, inspecting the mechanical components manufactured and report generation for Thirty Meter Telescope project.

1. Determined specification based on Fried parameter, Isoplantic angle and turbulence at the telescope site. 2. Calculated the number of actuators required by Deformable Mirror to make image correction, pupil plane diameter required for aberration estimation, and determined the f-ratio for each optical component. 3. Designed a diffraction limited Adaptive Optics (AO) system in ZEMAX for 1.3m telescope, involving lenses, deformable mirrors and lenslet arrays. 4. Did tolerancing of the AO design.

1. 2 months internship was offered in the Department of Physics, Hochschule Merseburg, Germany. 2. The job was to control the position of a work-piece in X, Y& Z direction in a Laser and Micromaterial processing machine. 3. This was achieved by creating a hardware control system and a software module in MATLAB based GUI architecture.

1. Single handedly worked on development, maintenance and enhancement of Reed Elsevier’s textbooks.elsevier.com, Mediarich and EFN applications. 2. Played instrumental role in identifying critical issues and resolving them. 3. Generated and Implemented value ideas to increase the product visibility on client sites to boost sale. 4. Responsible for maintaining source code and database at application and database servers after each deployment, documenting tasks, preparing reports and maintaining logs.
