Patent number: 8704144Abstract: A dual speed Read-Out Integrated Circuit employs a native pixel array with associated high resolution integration circuits for each pixel and a superpixel array created within the native pixel array by combination of native pixels for charge sharing integration in reduced resolution integration circuits simultaneously with the integration of the high resolution integration circuits. Switching control for readout of the high resolution integration circuits is accomplished at a first frame rate and switching control for readout of the reduced resolution integration circuits is accomplished at a second higher frame rate.Type: GrantFiled: October 27, 2011Date of Patent: April 22, 2014Assignee: Teledyne Scientific & Imaging, LLCInventors: James M. Elliott, Mark Alan Massie

Publication number: 20120133776Abstract: An infrared camera system for low contrast employs a focal plane array (FPA) of a plurality of detector diodes. A read out integrated circuit (ROIC) including a plurality of integration switches is connected to the plurality of detector diodes. A frame mean calculator receives raw data from the FPA and an integration time servo receives a frame mean from the frame mean calculator and a preprogrammed target mean. The integration time servo compares the frame mean and target mean and provides an integration time output to the ROIC responsive to the comparison for control of the integration switches.Type: ApplicationFiled: February 23, 2011Publication date: May 31, 2012Applicant: NOVA RESEARCH, INC.Inventors: Todd Cicchi, Eric Woodbury, Mark Alan Massie

Publication number: 20120113119Abstract: A method for super resolution enhancement of infrared imaging data employing an image array having simultaneous, high speed, randomly addressable windows of pixels for small regions of interest (ROI) within a large imaging sensor field of view. Data is retrieved from the ROI window pixels at an increased data rate and the array is dithered to produce sub-pixel motion consistent with the increased data rate. A selected super resolution (SR) algorithm is then applied to the data retrieved from the ROT window pixels at the increased data rate. The reduced data set substantially relieves the computational load on the processor compared with the requirement of performing SR processing on the entire frame of image data. The output from the SR algorithm is either used to replace the LR frame data in the image or is displayed as a separate image to the user.Type: ApplicationFiled: November 4, 2011Publication date: May 10, 2012Applicant: NOVA RESEARCH, INC.Inventor: Mark Alan Massie

Publication number: 20120025063Abstract: A dual mode amplifier for photodiode output reads a photodiode providing a current input. An integration capacitor is connected to receive the current input and connected to a voltage output node. An input capacitor is also connected to receive the voltage input and drives an operational amplifier having an output connect to the voltage output node. A correlated double-sample (CDS) capacitor is connected to the voltage output node and a sample and hold circuit incorporating a sample and hold capacitor for sampling the CDS capacitor. A log function on (LOGON) switch is connected between the operational amplifier output and the voltage output node and a reset switch connected to short the photodiode.Type: ApplicationFiled: July 27, 2011Publication date: February 2, 2012Applicant: Nova Research, Inc.Inventors: Eric Woodbury, Mark Alan Massie

Publication number: 20110073877Abstract: A Read-In Integrated Circuit scene generator incorporates an array of unit cells, with each cell having a switching control circuit. An array of emitting elements is associated with the unit cells and each element is connected with a lead to the switching control circuit of the associated cell. A first electrically conducting overlayer is deposited substantially covering the array of unit cells and connected for current supply. Each emitting element is connected to the first conducting overlayer and the first conducting overlayer includes vias through which each connecting lead from the emitting element to the switching control circuit extends. A second electrically conducting overlayer is deposited substantially covering the array of unit cells and connected for current return. Each switching control circuit is connected to the second conducting overlayer. The second conducting overlayer also has vias through which each lead from the emitting element extends to the switching circuit.Type: ApplicationFiled: September 28, 2010Publication date: March 31, 2011Applicant: NOVA RESEARCH, INC.Inventor: Mark Alan Massie

Patent number: 7808528Abstract: A variable acuity imager incorporates an array of detection elements for light energy, in the visible, infrared, ultraviolet, or light energy in another region of the electromagnetic spectrum with a means to change the spatial configuration of the array to include “superpixels” by combining energy detected by adjacent elements, thus permitting any number of high-resolution “foveal” regions to be placed within the confines of the focal plane array and moved around at the frame rate of the imaging device. Detectors to measure the pitch, yaw and roll angle rates of background imagery using velocity-sensing circuitry are employed for variation of the foveal regions to accommodate motion of the array.Type: GrantFiled: July 21, 2008Date of Patent: October 5, 2010Assignee: Nova Research, Inc.Inventors: Mark Alan Massie, Jon Paul Curzan, Christopher Robert Baxter, Ralph Roch Etienne-Cummings

Publication number: 20100053332Abstract: A longwave infrared (LWIR) camera system incorporates a prism having a reflecting face with an internal surface and an external surface, an input face and an output face. A visible light source provides light to the prism input face and an image detector is positioned to receive light from the prism output face. A plurality of bi-metal cantilevers are arranged in a MEMS array immediately adjacent the external surface of the reflecting face of the prism. Each of the bi-metal cantilever deflects based on absorbed infrared energy to contact the outer surface of the reflecting face. A CMOS image sensor is employed as the image detector.Type: ApplicationFiled: August 26, 2009Publication date: March 4, 2010Applicant: NOVA RESEARCH, INC.Inventor: Mark Alan Massie
