A super-resolution telescope. A target is illuminated with at least three laser beams, each beam having a slightly different frequency so as to produce an illumination pattern comprised of several sets of straight interference fringes which sweep across the target. The frequencies of the illumination beams are chosen so that each pair of beams has a unique beat frequency, and the corresponding fringe pattern for each pair sweeps over the target at a unique speed. By collecting a series of images, and demodulating them at the various beat frequencies, the downshifted spatial frequencies can be identified, correctly up-shifted, and fitted together with a set of special Fourier transform based algorithms to reconstruct high-resolution images. Applicants have performed laboratory experiments that this invention can provide resolution substantially better than diffraction limited resolution.

Super resolution telescope

A system and method for imaging far away fast moving objects such as satellites in low earth orbit. The object to be imaged is illuminated simultaneously with a composite beam comprised of a large number of separate laser beams from a large number of laser sources each from a separate position with each of the separate laser beams shifted in frequency with respect to each other beam so as to produce a large number of beat frequencies in the composite beam. The positions of the laser sources are changed rapidly during an illumination period of a few seconds. Light reflected from the object is collected in a large number of light buckets and information defining the intensity of the collected reflected light as a function of time is stored. The positions and frequencies of each of the laser sources are also recorded and stored as a function of time. The stored information defining the intensity of the collected reflected light is analyzed by one or more computer processors utilizing special algorithms to produce a image of the object.

Fourier telescopic imaging system and method

A disaster alert system and disaster alert devices for use in the system. Each disaster alert device includes a radio receiver, and a processor programmed to monitor radio transmissions from one or more central stations for disaster alerts directed to the location of the disaster alert device. Each alert device also includes an audio unit to alert personnel located at the site of the device to the precise nature of the disaster. The disaster alert devices are pre-programmed with information identifying the precise use location of the warning device. This use location information includes latitude and longitude of the use location and may also include other location information such as street address and zip code. Warnings are broadcast from central stations identifying with latitude and longitude information specific at-risk regions to which the warnings are directed which could be, for example, nationwide, statewide, countywide, or to much smaller regions, such as several houses on a single street or even a single residence. Each disaster alert device is preferably programmed to ignore all warnings directed to at-risk regions that do not include the latitude and longitude of the use location of the device.

Disaster alert device and system

Methods of applying laser light to the skin, and apparatus therefor, include methods for removing hair, for bleaching hair, for transdermal drug delivery, for sensing a body function, for skin tightening, and for imaging subsurface structures are described. The hair removal methods and the hair bleaching methods include infiltrating a transparent fluid with an index of refraction greater than that of skin tissue into hair ducts to help transmit the laser light down the hair ducts. The transdermal drug delivery and body function sensing methods include exfoliating layers of the stratum corneum from a section of skin with laser light. A transdermal drug delivery patch can be placed over the exfoliated skin section, or an electrical sensor can be placed over the exfoliated skin section. The skin tightening method includes implanting a light absorbing material in the dermis of a section of skin and illuminating the skin section to disturb the dermis in such a way as to cause a healing reaction that forms more collagen fibers. The imaging system includes a confocal microscope that has been adapted to view only a time-gated portion of laser light reflected from the skin.

Skin enhancement using laser light

Methods of applying laser light to the skin, and apparatus therefor, include methods for removing hair, for synchronizing hair growth, for stimulating hair growth, for treating Herpes virus, for reducing sweat and body odor, for in situ formation of a chromophore in hair ducts, for reducing light loss at the skin surface, for grafting of hair stem cells, and for removing keloid or hypertrophic scars. The hair removal methods include controlling the proportions of photomechanical and photothermal damage by selection of laser parameters, chromophore particle size and/or pulse duration, with optional dynamic skin cooling. Additional hair removal methods include infiltrating a photoactivated drug into hair ducts and exposing the skin to sunlight or administering an anti-proliferative agent into hair ducts, for example, by encapsulating the anti-proliferative agent in a slow release vehicle. The methods of treating Herpes virus, reducing sweat or body odor, and removing keloid or hypertrophic scars include infiltrating a light-absorbing contaminant into hair ducts or other openings in the skin and illuminating the contaminated skin section. The methods for stimulating hair growth include grafting of cloned auto hair stem cells the hair ducts or administering methionine to a skin section to increase hair growth. Apparatus useful in performing these methods include devices for making a smooth optical boundary between skin and air or for dividing a light beam into a plurality of smaller light beams, and dressings for use before, during and after laser illumination.

Methods and devices for inhibiting hair growth and related skin

A process for the long term or permanent prevention of growth of unwanted hair. The upper portions of hair ducts (i.e. portions near the skin surface) in a section of skin are infiltrated with a contaminant having a high absorption at at least one frequency band of light. The skin is then illuminated using a process having at least two distinct phases. In a 'mechanical' phase the skin section is illuminated (e.g., by a laser) with at least one short pulse of light sufficient to cause tiny explosions in the contaminant forcing portions of the contaminant more deeply into the hair ducts. During a 'thermal' phase the skin section is then illuminated so as to heat the contaminant substantially without further explosion or vaporization of the contaminant. The hot contaminant heats portions of the skin tissue immediately surrounding the contaminant to a temperature high enough and for a long enough period of time to devitalize the tissue. The process may also include a 'cleanup' phase, during which the skin section is illuminated with a few short pulses of light to cause additional explosions in and vaporization of portions of the contaminant then remaining in the ducts and additional damage to the skin tissue immediately surrounding the contaminant.
