The non-reference method is widely useful to estimation picture quality on the decoder side. In this paper, we discuss the estimation method for spatial blur that divides the frequency zones by the absolute value of 64 coefficients with an 8-by-8 DCT and compares them. It is recognized that absolute blur estimation is possible with the decoded picture only.

Preliminary experiments on non-destructive quantitative analysis of water vapor density in halogen lamps have been carried out. A working curve showing a relation between absorbance and water vapor density was successfully obtained by using frequency-stabilized InGaAsP/InP semiconductor laser spectrometric system.

Mass measurement system for the measurement of mass of substances placed in randomly vibrating circumstances has been developed. Mass measurement range was defined from 0 g to 400 g for the primary model with the measurement error of approximately 3% when randomly directional vibration of 6 m/sec2 acceleration was applied to the system.
