Patent number: 9261411Abstract: An uncooled microbolometer detector that includes a substrate, a platform held above the substrate by a support structure, at least one thermistor provided on the platform, and an optical absorber. The optical absorber includes at least one electrically conductive layer extending on the platform over and in thermal contact with the at least one thermistor and patterned to form a resonant structure defining an absorption spectrum of the uncooled microbolometer detector. The optical absorber is exposed to electromagnetic radiation and absorbs the electromagnetic radiation according to the absorption spectrum. A microbolometer array including a plurality of uncooled microbolometer detectors arranged in a two-dimensional array is also provided. Advantageously, these embodiments allow extending the absorption spectrum of conventional infrared uncooled microbolometer detectors to the terahertz region of the electromagnetic spectrum.Type: GrantFiled: December 19, 2012Date of Patent: February 16, 2016Assignee: INSTITUT NATIONAL D'OPTIQUEInventors: Hassane Oulachgar, Philip Mauskopf, Hubert Jerominek, Martin Bolduc, Samir Ilias, Christine Alain

Patent number: 7586678Abstract: High-resolution imaging systems are provided. In one embodiment, an imaging system based on a Cassegrain or Schmidt-Cassegrain objective, with coaxial primary and secondary mirrors, is provided with a microdisplacement mechanism acting on the secondary mirror to displace the image on a focusing array. In another embodiment, two co-axial Cassegrain-type objectives are provided one within the other with a common focal plane array, which therefore detects combined wide field-of-view and narrow field-of-view images.Type: GrantFiled: December 23, 2008Date of Patent: September 8, 2009Assignee: Institut National D'OptiqueInventors: Alain Bergeron, Hubert Jerominek, Nichola Desnoyers

Patent number: 7088493Abstract: A light modulator comprises a mirror, a substrate provided with at least one electrode, and at least one hinge extending between the substrate and the mirror. The mirror is flexible with the hinge being displaceable for allowing for the displacement and/or the deformation of the mirror. Typically, there are two symmetrically disposed hinges, each including upper and lower arms that define an angle therebetween. The upper arm is connected to the mirror, and the lower arm is mounted to the substrate. The upper and lower arms are adapted to pivot relative to one another thereby allowing the angle to vary and thus allowing the mirror to at least one of displace and deform. When unbiased, the mirror may be plane, convex or concave. When biased, the plane mirror adopts a curved attitude, whereas the curved mirror changes its curvature. The upper and lower arms of each hinge are V-shaped and define an apex. The apexes extend inwardly in a facing relationship.Type: GrantFiled: April 15, 2004Date of Patent: August 8, 2006Assignee: Institut National D'OptiqueInventors: Christine Alain, Francis Picard, Hubert Jerominek

Patent number: 6958478Abstract: In a microbolometer detector the individual transducers in the focal plane array are support by leg members that are attached to the underlying readout integrated circuit (ROIC) chip at locations underneath transducers other than transducer which they support. A variety of configurations are possible. For example, the leg members may be attached to the ROIC chip at locations under adjacent transducers on opposite sides or on the same side of the supported transducer, or at locations underneath transducers that are not immediately adjacent to the supported transducer. In this way the effective length of the leg members and therefore the thermal isolation of the transducer they support can be increased.Type: GrantFiled: May 19, 2003Date of Patent: October 25, 2005Assignee: Indigo Systems CorporationInventors: William A. Terre, James T. Woolaway, Hubert Jerominek, Christine Alain

Publication number: 20050230257Abstract: A process for making a microdevice that includes the steps of providing a base member and selectively electroforming a support member for supporting a microplatform with respect to the base member. The process also includes the steps of selectively electroforming the microplatform and forming a flexible hinge member for hingedly connecting the microplatform to the support member and allowing relative movement of the microplatform with respect to the support member. This microdevice, when compared to prior art devices, can have improved mechanical strength, rigidity, low deformation, and high planarity.Type: ApplicationFiled: January 31, 2005Publication date: October 20, 2005Applicant: Institut National D'OptiqueInventors: Hubert Jerominek, Patrice Topart

Patent number: 6780570Abstract: The method of fabricating a suspended microstructure with a sloped support, comprises the steps of (a) providing a member having three stacked up layers including a first substrate layer, a second temporary layer and a third photoresist layer; (b) photolithographically transferring a sloped pattern to the third photoresist layer by means of a grey scale mask; (c) etching the second layer through the third layer resulting from step (b) to obtain a surface with at least one continuous slope with a predetermined angle with respect to the first substrate layer; (d) depositing a fourth layer on the previous layers; (e) etching the fourth layer to obtain the sloped support; (f) (i) depositing a fifth planarization layer, (ii) depositing a sixth layer, and (iii) etching the sixth layer; and (g) removing the second layer and the fifth layer to obtain the suspended microstructure with the sloped support. The invention is also concerned with a suspended microstructure fabricated by the method.Type: GrantFiled: June 25, 2001Date of Patent: August 24, 2004Assignee: Institut National d'OptiqueInventor: Hubert Jerominek
