Forza Silicon developed the PTC ImageJ plugin to quickly analyze and plot the Photon Transfer Curve of a set of images. We’ve found it useful to:
- cross-check and validate other characterization results
- give quick, initial estimates of the pixel performance
- highlight non-linearity problems
The Photon Transfer Curve, or PTC, is a useful tool for analyzing the performance of image sensors. This plugin computes the PTC, and gives a graphical plot from which the conversion gain and read noise can be fit to the PTC curve. Inspiration for this plugin came from a course taught by Dr. Albert Theuwissen on CMOS image sensor characterization. (http://www.harvestimaging.com/)
