The radiometric calibration of the Time delay and integration Charge-coupled Device (TDI CCD) imaging system is a necessary part in the manufacturing TDI CCD camera. The radiometric calibration of the TDI CCD remote sensing camera is done in the State Key Laboratory of Applied Optics. The integration sphere is used for simulating different radiance
which is decided by the different sun vertex angle and different reflectivity of the ground. The parameters of the gain and stage of the TDI CCD remote sensing camera are given through the analyzing of outcome of the experiment. The outcomes are used in the practice and the errors are discussed in the end of the experiments.

Optical interconnection is the key technique of high-speed optical information process and optical communication. A lot of approaches for optical interconnection have been proposed since Goodman in Stanford University firstly proposed the optical interconnection for very large scale integrated circuits technology. A dynamical addressing device for optical interconnection was designed and fabricated in this paper. This optical device is based on one-dimensional nonlinear photonic crystal made on the planar waveguide. The nonlinear materials ZnS and ZnSe
which have large nonlinear refractive index coefficients
were alternately deposited on the waveguide to form one-dimensional photonic crystal. The Bragg condition is changed when the input power of the control light increased due to the nonlinear characters of the materials
thus the reflective angle of the signal light can be changed with the input power change of the control light. In our experiment
when increasing the power density of control light from 0 to 2.60X105W/cm 2
the angle of the signal beam can be changed about 20. The interconnection characteristics were investigated in theory and in experiment. The testing data agree well with theoretical predictions. This kind of devices is promising to use in the all-optical interconnection
optical information processing and optical communication.
