Abstract: PURPOSE:To save the labor and time for a focus adjustment and to eliminate an error due to individual differences by scanning the same object successively, by comparing levels of two successive video signals with each other and by making the focus adjustment with the comparison output. CONSTITUTION:Firstly, vertical scan control part 5 sets a vertical scanning mirror in the center of an image, and infrared rays IR from an object are incident to infrared-ray detector 3 via a condenser mirror and converted into a video signal. This video signal is inputted to focus adjustment control part 6 and its maximum signal level near the center of the signal waveform is extracted by circuit 61 and stored in memory 63 temporarily. In this state, the condenser mirror is moved slightly and a maximum signal level is extracted from the video signal at that time and compared by comparing circuit 62 with the stored signal level in memory 63. Then, the condenser mirror is shifted slightly in position toward focus matching according to the comparison result to make a focus adjustment.

Title: Detecting method for concentration of content in sample by using laser spectroscopy
Inventor: AZUMA YOJI
IPC: G01N21/3504
Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To provide a detecting method in which the concentration of a content in a sample can be detected precisely even when a change in the temperature of the sample is large. SOLUTION: A light absorption spectrum is measured by laser spectroscopy (S100). A plurality of energy levels are selected on the basis of the light absorption spectrum (S20). Light absorption intensities at the energy levels are found respectively (S22). On the basis of the ratio of the obtained light absorption intensities, the temperature of an exhausts gas is found by referring to a reference table (S21). Then, an optical absorption coefficient is corrected by the temperature of the exhaust gas (S31). Light absorption intensities at the energy levels whose absorption coefficient is corrected are found (S32). By using the corrected optical absorption coefficient and the light absorption intensities, the concentration of carbon monoxide in the exhaust gas is found (S 33).  In this manner, since the optical absorption coefficient is corrected by the temperature of the exhaust gas, the concentration can be detected precisely even when a change in the temperature of a sample is large.
