Patent number: 7433042Abstract: A hyperspectral imager that achieves accurate spectral and spatial resolution by using a micro-lens array as a series of field lenses, with each lens distributing a point in the image scene received through an objective lens across an area of a detector array forming a hyperspectral detector super-pixel. Spectral filtering is performed by a spectral filter array positioned at the objective lens so that each sub-pixel within a super-pixel receives light that has been filtered by a bandpass or other type filter and is responsive to a different band of the image spectrum. The micro-lens spatially corrects the focused image point to project the same image scene point onto all sub-pixels within a super-pixel.Type: GrantFiled: July 7, 2007Date of Patent: October 7, 2008Assignee: Surface Optics CorporationInventors: David B.

Each sub-pixel within a super-pixel has a bandpass or other type filter to pass a different band of the image spectrum. The micro-lens spatially corrects the focused image point to project the same image scene point onto all sub-pixels within a super-pixel. A color separator can be used to split the image into sub-bands, with each sub-band image projected onto a different spatially corrected detector array. A shaped limiting aperture can be used to isolate the image scene point within each super-pixels and minimize energy coupling to adjacent super-pixels.Type: GrantFiled: November 9, 2004Date of Patent: July 10, 2007Assignee: Surface Optics CorporationInventors: Mark Dombrowski, Brian Catanzaro

Patent number: 5949074Abstract: A spectroradiometer images a scene as a repeating sequence of spectral images, each of which spectral images depicts the scene at a preselected wavelength. In a preferred embodiment, the image is of size 256 by 192 pixels, and the sequence repetition rate is about 20-30 cycles per second. Full spectral analysis on the resulting sequences is performed substantially in real time. The spectroradiometer includes a collector of energy in the X-ray or infrared ranges with a lens, a circularly variable spectral filter, and a gate which gates the output of the filter to a detector array which outputs the sequence of electronic spectral images. These images are corrected for systematic errors and calibrated, and correlated with a preselected spectral response function. The image may be further post-processed and displayed in video format or used otherwise.Type: GrantFiled: October 6, 1998Date of Patent: September 7, 1999Assignee: Surface Optics CorporationInventors: Mark Dombrowski, James Lorenz

Patent number: 5070251Abstract: A standby power supply system (SPS) is connected to supply power to a load by way of a transfer switch, to replace power from the AC lines, when the AC line fails to provide sufficient voltage to operate the load (e.g., 85% of nominal RMS voltage usually 120 VAC-RMS). The SPS has an inverter which switches voltage from a battery to generate AC power when the line fails. The inverter is controlled by varying the width of switching pulses in order to regulate the AC output voltage and compensate for reductions in battery voltage as the battery discharges. The AC output voltage is also synchronized with the line voltage when the line voltage returns (increases to greater than 85% of nominal value) so that on switch over back to the AC line, the AC waveform applied to the load does not change substantially before and after switch over.Type: GrantFiled: May 25, 1990Date of Patent: December 3, 1991Assignee: General Signal CorporationInventors: Bruce R. Rhodes, Dave Bollinger, Mark Dombrowski
