At the end of this article a simulation result was given, which is in agreement with the preliminary analysis.

Abstract:Triple correlation peak inspecting technique (TCPIT) was adopted for the signal processing of IR systems in detecting sub pixels or point targets. Investigations show that the signal to noise ratio (SNR) can be improved by about 23dB with the input peak SNR of 0.84 and the input power SNR of -9.73dB. The 2 D graphics method for implementation of TCPIT was recommended. Using this approach,the amplitude information of point targets can be still effectively extracted from noises with the input peak SNR lowered to 0.48 and the input power SNR lowered to -14.24dB.

Abstract:A unified miniature optically pumped NH 3 FIR laser (unified mini OPFIR cavity laser),including a mini TEA CO 2 pump laser, was developed. The optimum operation of the unified mini-OPFIR cavity laser was studied experimentally. The relations among FIR laser output power, operating gas pressure, length and coupling condition of the cavity were measured. lt was found that the very wide band FIR laser emission was a common feature of the mini OPFIR cavity laser. This will be a new way for wide range frequency tuning of FIR laser.

Abstract:A new method for the determination of the cancerous cells was proposed. By means of the high resolution of FTIR, the comparison and study on the normal human cells and cells of more than1000 patients suffering from the cervical carcinoma were conducted. It was preliminarily concluded that by this method the obvious difference between the cancer cells and the normal ones can be explained from the molecular level. Moreover, through the interpretation of the spectrum, the main reasons causing the change of the spectrum and the possible mechanism of the cells canceration can be directly explained and thus the course of illness can be forecasted and diagnosing cancer in an early stage can be done.

Abstract:By measuring the dynamic response in PC type HgCdTe detectors, it was found that at the operating temperature (77K), after laser irradiation, the conductivity of detectors changes (showing memory), and responsibility is raised up. This effect will remain unchanged for a long term at the operating temperature. When the temperature is raised to room temperature, the memory function disappears. Various measurement results were given on this effect and its mechanism was analyzed in this paper.
