Optical Tweezers Calibration Using Digital Filters program (OTCUDF program) calculates the optical stifness as well as the position detector calibration factor from a single voltage data set comming from the back focal plane detection using a quadrant photodiode.
Below you will find a .zip file containning Matlab code, some required files, and a manual for the proper use of the program.
