CCD Aerial Camera Modulation Transfer Function Test and Analysis

Kinetic PCR Analysis Using a CCD-camera

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...

The Design and Realization of Large Plane Colour Ccd Digital Aerial Camera System

On the basis of a size single plane array CCD (SPAC-1), we study and establish a digital aerial photogrammetry camera system, which adopts a “3+1”modular design method, i.e., three k k 9 9 × k k 2 2 × CCD modules for recording RGB band images and one CCD module for recording the panchromatic image. Every module has an independent optical system, with the same ground coverage obtained at the exp...

Make Wide-angled Aerial Camera by Combining Small-sized Areal Array Ccd Sensors

A new method for combining small-sized areal array CCD sensors to make one wide-angled digital aerial photography system is studied in this paper. The method is to install several small-sized areal array CCD cameras in the way that their perspective projecting centers form a line or a square, with their principal optical axes slanting fixed angle along designed directions. Such installation aim...

Methods for CCD Camera Characterization

In this paper we present methods for characterizing CCD cameras. Interesting properties are linearity of photometric response, signal-to-noise ratio (SNR), sensitivity, dark current and spatial frequency response (SFR). The techniques to characterize CCD cameras are carefully designed to assist one in selecting a camera to solve a certain problem. The methods described were applied to a variety...
