Title: Pyroelectric infrared sensor
Inventor: HIRAKAWA KOICHI
IPC: G01V8/12
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To obtain a pyroelectric infrared sensor in which good field of view characteristics are ensured by constituting the sensor of a diffraction optical element, split concentrically into more than one section and having a region where the design wavelength increases toward the outside, thereby suppressing chromatic aberration. SOLUTION: Infrared rays 6 from an object are condensed through a diffraction optical element 5, having a design wavelength of 10μm in the central part and 12μm on the outside, for example, and then passed through an infrared transmission window 4 to a light-receiving part 1, comprising a pyroelectric where the quantity of incident light is measured. Since the chromatic aberration of the element 5 is inversely proportional to the period of the fringe thereof, blurings due to chromatic aberration can be reduced on the pyroelectric, by increasing the design wavelength in the outside region where the period of fringe is short, thereby lengthening the period of fringe. Similar effect can be attained by increasing the designed focal distance in the outside region.  A diffraction optical lens having irregular, e.g. saw-tooth or stepwise, cross-section, depending on the amount of phase modulation, may be employed as the element 5 in order to increase the output. The element 5 may be mounted directly on the transmission window 4.

Abstract: PURPOSE:To perform accurate control in matching relation to the frequency of a connected commercial power supply by detecting frequency on the basis of the count value of the second counter and judging whether the detected frequency is effective on the basis of the first count value. CONSTITUTION:At each time when the AC signal of a commercial power supply 1 crosses the mean DC level, a zero cross signal is generated.

The zero cross signals inputted during said period or the pulse signals equal thereto are counted by the second counter of the microcomputer 11 and frequency is detected on the basis of the count value of the first counter and it is judged whether the detected frequency is effective on the basis of the count value of the second counter. By this method, accurate control can be performed in matching relation to the frequency of the connected commercial power supply.
