Title:
FORMATION METHOD OF HIGH-RESOLUTION INFRARED IMAGE AND UNIDIRECTIONAL SCANNING HEAT-RAY CAMERA FOR ITS EXECUTION
Document Type and Number:
Japanese Patent JPH0630340
Kind Code:
A
Abstract:
PURPOSE: To provide the video picture of high geometrical resolution by reducing the size of the unit sensor area of a pseudo linear sensor and using a sampling frequency lower than that twice as much as the maximum frequency of a sam pled signal. CONSTITUTION: The driving motor M of a mirror 2 has control which is servo- connected to an instruction value outputted by a clock signal generator G. For correcting angular vibration following a horizontal direction, a low capacity memory 11 is inserted between an inverter 8 and a processing circuit 9. An information element, which is related to the line of slight and which is supplied by a gyroscope 13, is introduced to a memory 11 in the form of an angular deviation correction signal. In such a case, the spatial sampling frequency twice as much as the interruption frequency Fc of the modulation transmission function MTF of the sensor namely twice as much as an actual interruption frequency positioned in a section Fc0 -Fc is used.
