Full Poincaré Mueller Polarimetry Using a CCD Camera

CCD camera full range pH sensor array.

Changes in colors of an array of optical sensors that responds in full pH range were recorded using a CCD camera. The data of the camera were transferred to the computer through a capture card. Simple software was written to read the specific color of each sensor. In order to associate sensor array responses with pH values, a number of different mathematics and chemometrics methods were investi...

ellipsometry and Mueller matrix polarimetry

We characterized two samples consisting of photoresist layers on silicon with square arrays of square holes by spectroscopic ellipsometry (SE) and Mueller matrix polarimetry (MMP). Hole lateral dimensions and depths were determined by fitting either SE data taken in conventional planar geometry or MMP data in general conical diffraction configurations. A method for objective determination of th...

Intelligent Surveillance Using an Omnidirectional CCD Camera

Video surveillance, object tracking and activity monitoring are some of the important issues for a homecare robotic system. In this work, an omnidirectional video camera is adopted to provide a 360 degree view angle of the indoor scene in a single image. Some basic functions for smart living and elderly care, such as motion detection, object tracking and target behavior analysis, are implemente...

CCD Camera Gain Measurement

The gain of a CCD camera is the conversion between the number of electrons ("e-") recorded by the CCD and the number of digital units ("counts") contained in the CCD image. It is useful to know this conversion for evaluating the performance of the CCD camera. Since quantities in the CCD image can only be measured in units of counts, knowing the gain permits the calculation of quantities such as...
