Infrared detector having at least one switch for modulation and/or bypass
First Claim
1. A detector comprising:
- at least one thermal sensing element being configured to;
receive at least one oscillating signal;
detect at least a portion of a thermal output from an object;
generate an electrical output signal indicative of the detected thermal output; and
modulate the electrical output signal with the at least one oscillating signal to provide a modulated output signal indicative of at least a portion of the image of the object;
a converter configured to convert the modulated output signal into a digital modulated output signal; and
a demodulation circuit configured to demodulate the digital modulated output signal to provide at least a portion of an image of the object.

Abstract
An infrared (IR) detector including a plurality of thermal sensing elements for generating an image of an object is provided. The IR detector comprises a first thermal sensing element and includes a thermopile and a first switch. The thermopile is configured to receive at least a portion of a thermal output from the object and to provide a modulated electrical output indicative of at least a portion of the received thermal output. The first switch is operatively coupled to the thermopile and is configured to provide a bypass in the event the thermopile is damaged such that remaining thermal sensing elements of the plurality of thermal sensing elements are capable of providing an electrical output therefrom.
