摘要： A hybrid thermal detector and method for producing same where the optical coating 32 of the hybrid thermal detector has elongated parallel thermal isolation stots 62 along one axis. The elongated parallel slots 62 improve the acuity, or MTF of the resultant image produced by the detector along one axis. The optical coating 32 may be corrugated, or elevated, in order to add structural support and allow mechanical compliance along the axis of the slots.

摘要： A thermal isolation structure (10) is disposed between a focal plane array and an integrated circuit substrate (12). The thermal isolation structure (10) includes a mesa-type formation (16) and a mesa strip conductor (18, 26) extending from the top of the mesa-type formation (16) to an associated contact pad (14) on the integrated circuit substrate (12). After formation of the mesa-type formation (16) and the mesa strip conductor (18, 26), an anisotropic etch using the mesa strip conductor (18, 26) as an etch mask removes excess mesa material to form trimmed mesa-type formation (24) for improved thermal isolation. Bump bonding material (20) may be deposited on mesa strip conductor (18, 26) and can also be used as an etch mask during the anisotropic etch. Thermal isolation structure (100) can include mesa-type formations (102), each with a centrally located via (110) extending vertically to an associated contact pad (104) of integrated circuit substrate (106). A conductor (108) is deposited on top of mesa-type formation (102), along the walls of via (110), and overlaying contact pad (104). An anistropic etch using the conductor (108) as an etch mask removes excess mesa material (118) for improved thermal isolation.

摘要： A thermal detection system (100, 200) includes a focal plane array (102, 202), a thermal isolation structure (104, 204) and an integrated circuit substrate (106, 206). The focal plane array (102, 202) includes thermal sensors (114, 214) formed from a pyroelectric element (116, 216), such as barium strontium titanate (BST). One side of the pyroelectric element (116, 216) is coupled to a contact pad (110, 210) disposed on the integrated circuit substrate (106, 206) through a mesa strip conductor (112, 212) of the thermal isolation structure (104, 204). The other side of the pyroelectric element (116, 216) is coupled to a common electrode (120, 220). In one embodiment, slots (128) are formed in the common electrode (120) intermediate the thermal sensors (114) to improve inter-pixel thermal isolation. In another embodiment, slots (236) are formed in the optical coating (224) to improve inter-pixel thermal isolation. The common electrode (120, 220) may be formed from a thermally insulating material, such as a silicon monoxide and chromium matrix (cermet) or other metal oxide.

The system (10) includes a thermal detector (28 or 30) made from a layer of temperature sensitive material forming a first element of a signal-producing circuit (54). The first element (28 or 30) has either a resistance or capacitance value depending on its temperature.

摘要： A thermal imaging system (10) contains a focal plane array (30) including a plurality of thermal sensors (32) mounted on a substrate (62). Each thermal sensor (32) includes a film layer (34) of infrared sensitive material which is both electronically and thermally isolated from the associated integrated circuit substrate (62). An image may be formed on the film layer (34) in response to infrared radiation from a scene (12).

摘要： A thermal imaging system (10) contains a focal plane array (14) including a plurality of thermal sensors (50) mounted on a substrate (52). The focal plane array (14) generates both a reference signal which represents the temperature of the substrate (52) and a biased signal corresponding to the total radiance emitted by a scene (11). Electronics (16) process the reference signal and the biased signal to obtain an unbiased signal representing radiance differences emitted by objects in the scene (11). A thermoelectric cooler/heater (38) may be provided to optimally adjust the temperature of the substrate (52) to improve overall image quality. Each thermal sensor (50) contains an electrode (66 and 68) that electrically couples the thermal sensor (50) to the substrate (52) and also allows the thermal sensor (50) to deflect, contact, and thermally shunt with the substrate (52).
