This paper describes the design and performances of a novel focal-plane array (FPA) containing pixels of double bimaterial-layer cantilevers without silicon (Si) substrate for being applied in the uncooled optical-readable infrared (IR) imaging system. The top layer of the cantilever pixels is made of two materials with large mismatching thermal expansion coefficients: silicon nitride (SiNx) and gold...
This paper presents the structure, fabrication and imaging results of a novel optical-readable uncooled infrared detector, in which substrate-free structure is employed to replace the generally used sacrificial layer structure. This substrate-free detector with 100 times 100 pixels can eliminate the loss of 46% of the incident radiation caused by substrate reflecting. The inclination angle of the...
