Patent number: 8599303Abstract: The present invention determines the dimensions and volume of an object by using a novel 3-D camera that measures the distance to every reflective point in its field of view with a single pulse of light. The distance is computed by the time of flight of the pulse to each camera pixel. The accuracy of the measurement is augmented by capture of the laser pulse shape in each camera pixel. The camera can be used on an assembly line to develop quality control data for manufactured objects or on a moving or stationary system that weighs as well as dimensions the objects. The device can also ascertain the minimum size of a box required to enclose an object.Type: GrantFiled: October 22, 2012Date of Patent: December 3, 2013Assignee: Advanced Scientific Concepts, Inc.Inventor: Roger Stettner

Publication number: 20130128257Abstract: A three dimensional imaging camera comprises a system controller, pulsed laser transmitter, receiving optics, an infrared focal plane array light detector, and an image processor. The described invention is capable of developing a complete 3-D scene from a single point of view. The 3-D imaging camera utilizes a pulsed laser transmitter capable of illuminating an entire scene with a single high power flash of light. The 3-D imaging camera employs a system controller to trigger a pulse of high intensity light from the pulsed laser transmitter, and counts the time from the start of the transmitter light pulse. The light reflected from the illuminated scene impinges on a receiving optics and is detected by a focal plane array optical detector. An image processor applies image enhancing algorithms to improve the image quality and develop object data for subjects in the field of view of the flash ladar imaging camera.Type: ApplicationFiled: September 14, 2012Publication date: May 23, 2013Applicant: ADVANCED SCIENTIFIC CONCEPTS INC.Inventors: Roger Stettner, Howard Bailey, Brad Short, Laurent Hueghebaert, Patrick Gilliland

Patent number: 6690019Abstract: A device for the high-speed analysis of photon- or particle-generated image data or for the high-speed energy-discrimination analysis of photon- or particle-counting data. A sensor collects the photons or particles on an array of solid state detectors, as electrical analog signals, and stores the analog-signal information on capacitors of readout arrays associated with the detector arrays. Image-related signals are transferred to integrated circuit chips containing an array of correction processor unit cells. Corrected signals are transferred to an analog image processor. Particle-counting data is transferred directly from the readout array chips to the analog image processor having circuitry for implementing an image processing or energy discrimination algorithm.Type: GrantFiled: February 22, 2002Date of Patent: February 10, 2004Assignee: Advanced Scientific Concepts, Inc.Inventors: Roger Stettner, Howard W.

Patent number: 6414746Abstract: A three dimensional imaging device is presented which uses a single pulse from a pulsed light source to detect objects which are obscured by camouflage, fog or smoke but otherwise enveloped by a light-transmitting medium. The device simultaneously operates in two modes, light reflected from the nearest object is processed to form a three-dimensional image by an array of pixels. This first image is based upon the light-pulse transit time recorded in each pixel. Each pixel also contains a high-speed analog memory that sequentially stores reflected signals at a repeated time interval. The first reflection acts as a time base that controls when the analog memory begins or ends the storage sequence. The first return could be from a camouflage net and the amplitudes of the return signals, after the first return, would then be from objects behind the net. Computer processing these amplitudes reveals the three-dimensional nature of the obscured objects.Type: GrantFiled: November 24, 1999Date of Patent: July 2, 2002Assignee: Advanced Scientific Concepts, Inc.Inventors: Roger Stettner, Howard W.

Patent number: 6362482Abstract: A device for the high-speed analysis of photon- or particle-generated image data or for the high-speed energy-discrimination analysis of photon- or particle-counting data. The device uses a sensor that collects the photons or particles on an array of solid state detectors, as electrical analog signals, and stores the analog-signal information on capacitors of readout arrays associated with the detector arrays. Integration of the photon or particle flux signals on the readout arrays proceeds for a given time frame and then image-related signals are transferred to an analog correction processor. The analog correction processor is comprised of one or more integrated circuit chips where each chip contains an array of correction processor unit cells. In these unit cells signals are corrected, in parallel, for gain and offset nonuniformities in the detection and processing chain. Corrections to all the signals are made in a time frame or less and the information is then transferred to an analog image processor.Type: GrantFiled: September 16, 1998Date of Patent: March 26, 2002Assignee: Advanced Scientific Concepts, Inc.Inventors: Roger Stettner, Howard W.

Patent number: 6201257Abstract: An energy dispersive x-ray and gamma-ray photon counter is described. The counter uses a photon sensor which incorporates a unique photocathode called Advanced Semiconductor Emitter Technology for X-rays (ASET-X) as its critical element for converting the detected photons to electrons which are emitted into a vacuum. The electrons are multiplied by accelerations and collisions creating a signal larger than the sensor noise and thus allowing the photon to be energy resolved very accurately, to within ionization statistics. Because the signal is already above the sensor noise it does not have to be noise filtered therefore allowing high-speed counting. The photon sensor can also be used as a device to visualize and image gamma-ray and x-ray sources.Type: GrantFiled: July 22, 1998Date of Patent: March 13, 2001Assignee: Advanced Scientific Concepts, Inc.Inventors: Roger Stettner, Howard W.

Patent number: 6133989Abstract: A three dimensional imaging device is presented which uses single pulse from a pulsed light source for detecting objects enveloped by a light-transmitting medium such as the earth's atmosphere or free space. By means of switching off a ramping voltage, individually for each object pixel, the time of arrival of the reflected pulse is recorded. This time is related to the third object dimension. The device consists of the pulsed light source, optics for collecting the reflected light, a sensor for detecting the light, drive and output electronics for timing and signal conditioning of data generated by the sensors and a computer for processing the sensor data and converting it to a three dimensional image. The sensor collects and processes the light data in a unique manner, using a hybrid. The hybrid is actually a two dimensional array of collectors or detectors combined in very close proximity with their own processing electronics.Type: GrantFiled: June 19, 1996Date of Patent: October 17, 2000Assignee: Advanced Scientific Concepts, Inc.Inventors: Roger Stettner, Howard W.
