“…For instance, accuracy of stiffness calibration of AFM cantilevers depends on the accuracy of the detected position of the cantilever tip [20,[26][27][28][29][30]. Position detection is also fundamental in optical trapping for the measurement of the trap stiffness [31][32][33][34][35][36][37], experimenting with molecular motors [38][39][40][41][42][43][44][45][46], measuring the mechanical properties of polymers [47][48][49][50], and the study of colloid particles [51][52][53][54] be used as incoherent detectors of vibration [65,66]. Non imaging techniques uses position sensitive detectors (PSD) [67] and quadrant photodetectors (QPD) [68].…”

knowledge and experience. They have been a true support group during tough times. This research work would have been much more difficult without their support. I cannot thank enough Pranoy Deb Shuvra, for being an extraordinary friend, over the last 15 years. Many thanks to Anam Chandra Paul and Abdullah Al Mamun for supporting me countless times. Finally, I want to thank my parents Sre Jagadish Chowdhury and Rathna Rani Devi for their endless support, patience and guidance.

The row scanning mechanism of a rolling shutter camera can be used to infer high-frequency information from a low-frame-rate video. Combining the high intensity of laser speckle and high row-sampling rate of a rolling shutter, extreme detectable vibration frequency limited by rolling shutter camera imaging is experimentally demonstrated. Using a commercially available industrial camera at a frame rate of 70 fps, a vibration signal with a frequency of 14.285 kHz is extracted that corresponds to an inter-row sampling period of 35 µs and a sampling frequency of 28.57 kHz. Connected component and centroid alignment algorithms are used to extract the inter-row vibration displacement. The parameters that limit the highest and lowest detectable frequencies are discussed.
