Infrared detector with vibrating chopper
First Claim
1. An infrared ray detector comprising:
- an infrared ray detecting body,a pair of opposing portions having a plurality of infrared ray non-transmitting portions and infrared ray transmitting portions,intermitting means for intermitting infrared rays incident upon said infrared ray detecting body through said pair of opposing portions, said intermitting means comprising a vibrator connected to one of said pair of opposing portions, wherein a state that the infrared ray transmitting portions of both opposing portions are substantially overlapped with respect to each other and the infrared ray non-transmitting portions of both opposing portions are substantially overlapped with respect to each other, and a state that the infrared ray non-transmitting portions and transmitting portions of one opposing portion are substantially overlapped with the infrared ray transmitting portions and non-transmitting portions of the other opposing portion, respectively, are alternately repeated, anda housing containing said infrared ray detecting body, said pair of opposing portions and said intermitting means, said housing being provided with an opening for incidence of infrared rays.

Abstract
An infrared ray detector comprising an infrared ray detecting body, a pair of opposing portions, a bimorph vibrator connected to the pair of opposing portions for intermitting infrared rays incident upon the detector, and a housing containing these elements, the housing being provided with an opening for incidence of infrared rays. The pair of opposing portions comprise infrared ray transmitting portions and infrared ray non-transmitting portions. The infrared ray transmitting portions in one of opposing portions is periodically overlapped by the bimorph vibrator with the infrared ray transmitting portions or infrared ray non-transmitting portions in the other opposing portion, so that incident infrared rays are intermitted.
