This paper presents a real time implementation of Non Uniformity Correction (NUC). Two point correction and one
point correction with shutter were carried out in an uncooled imaging system which will be applied to a missile
application. To design a small, light weight and high speed imaging system for a missile system, SoPC (System On a
Programmable Chip) which comprises of FPGA and soft core (Micro-blaze) was used. Real time NUC and generation of
control signals are implemented using FPGA. Also, three different NUC tables were made to make the operating time
shorter and to reduce the power consumption in a large range of environment temperature.
The imaging system consists of optics and four electronics boards which are detector interface board, Analog to Digital
converter board, Detector signal generation board and Power supply board. To evaluate the imaging system, NETD was
measured. The NETD was less than 160mK in three different environment temperatures.
We demonstrate LPWG in sol-gel material with replica molding and stamping technique. The grating structures were fabricated on top and bottom of the same ridge waveguide and operate at both communication wavelengths 1550 and 1310 nm respectively.
