Problems solved by technology

IR sensors and IR sensor arrays are therefore classified as so-called "dual-use" products and may be subject to use or export restrictions even if said IR sensors and IR sensor arrays are intended only for civilian use
[0004] There is therefore a need for infrared sensors and infrared sensor arrays that are unsuitable for military applications due to their limited functionality and methods for operating infrared sensors and infrared sensor arrays that do not permit the use of infrared sensors in military applications and IR sensor arrays or make the use of IR sensors and IR sensor arrays in military applications not of interest

Embodiment Construction

[0026] figure 1 A schematic diagram of a sensor system 10 with a sensor device 1 and an evaluation circuit 4 is shown. The sensor device 1 can have, for example, an infrared sensor 2 or an array of infrared sensors 2 and at least one acceleration sensor 3 . The sensor device 1 can have, for example, a microelectromechanical-based sensor (MEMS sensor) and be designed, for example, in SOI technology (“silicon on insulator”). The number of pixels (Pixel) of infrared sensor 2 or infrared sensor array 2 and the number of acceleration sensors 3 are in figure 1 are shown as examples only and are not restrictive in principle.

[0027] Infrared sensor 2 can be designed, for example, to detect radiation in the far infrared range (FIR, “far infrared”) of an object to be mapped (abzubildenden) and to output infrared image data 4 a. In this case, the infrared sensor 2 or the infrared sensor array 2 can have a main detection direction which is substantially perpendicular to the active su...

Abstract

The invention relates to a sensor arrangement (1) comprising an infrared sensor (2), which is designed to detect infrared radiation and output infrared image data (4a), and at least one acceleration sensor (3), which is designed to detect an instantaneous acceleration of the sensor arrangement (1) and output acceleration data (4b), wherein the output of infrared image data (4a) from the infrared sensor (2) is blocked if the instantaneous acceleration of the sensor arrangement (1) exceeds a predeterminable threshold value.

Description

technical field [0001] The invention relates to a system with an integrated infrared sensor and an acceleration sensor and a method for operating an infrared sensor with an acceleration sensor, in particular for domestic use. Background technique [0002] Infrared sensors, in particular in the far infrared range (FIR, “far infrared”) are used for various imaging methods, for example in land-based vehicles for pedestrian detection or for thermal imaging cameras. Infrared sensors can be produced in arrays of microelectromechanical structures (MEMS, “microelectromechanical structures”). Publications DE 10 2008 041 587 A1 and WO 2007 / 147663 A1 disclose, for example, MEMS-based infrared sensors. [0003] Infrared sensors and infrared sensor arrays may be used in military applications in addition to civilian applications, such as in imaging for the control of missiles or other military flying objects. Publication US 6,279,478 B1 for example discloses the use of infrared sensors ...
