This image was created by digitising a negative in the collection provided by Mr. C. Gourishankar's family. The negative was in an envelope containing photographs of equipment and instruments used for vibration experiments in the Machine Dynamics Laboratory of the Applied Mechanics Department.

This photograph is that of a Storage Cathode-Ray Tube (Storage CRT) oscilloscope. The figure displayed on the oscilloscope’s screen is the phase plane corresponding to a vibration signal representing a resonant condition.

A similar photograph (ID: 001/0272/IMG_0221) has also been found in the same album.

The Heritage Centre thanks Prof. S. Narayanan (Department of Applied Mechanics) for the information provided.

C. Gourishankar. A geologist by qualification, Gourishankar started his career as a photographer after working for many years with the Geological Survey of India. In everything that he did, Gourishankar strove to achieve flawlessness and impeccable quality. Thus his photography too was characterised by this drive for perfection. Every photograph that Gourishankar took was meticulously planned and shot, and printed with diligence and patience. Gourishankar carried out most of the official photography at IIT Madras in the 1960s.
