Optical Confocal Device Having A Common Light Directing Means

View page
US Patent:
6399936, Jun 4, 2002
Filed:
Sep 28, 1999
Appl. No.:
09/407458
Inventors:
Zhijiang Hang - Lexington MA
Victor Lazarev - Burlington MA
Robert H. Webb - Lincoln MA
Assignee:
New Dimension Research Instrument, Inc. - Woburn MA
International Classification:
H01J 314
US Classification:
250216, 2502081, 257 82
Abstract:
A confocal scanning imaging device for viewing an object includes an array of independently addressable microlasers and an array of detectors for detecting light from an object to which light from the microlasers has been directed. The array of microlasers and the array of detectors are combined into a single array, such as on a single chip, and in a pattern constructed and arranged so that different detectors are adjacent to each microlaser so that light from an illuminated object may be directed back to the vicinity of the illuminating microlaser and be detected by the adjacent detector(s). An optical arrangement directs light generated by the microlasers onto an object and directs light from an object so illuminated onto detectors adjacent to the illuminating microlaser. The optical arrangement includes a bilens and a matching lens system including two objective lenses. A microlens of pitch substantially identical to the pitch of the microlaser array collimates light generated by the microlasers.

Monolithic Vcsel-Based Optical Pickup And Servo Control Device

US Patent:
6614825, Sep 2, 2003
Filed:
Oct 5, 2000
Appl. No.:
09/680241
Inventors:
Zhijiang Hang - Lexington MA, 02173
Victor Lazarev - Burlington MA, 01803
International Classification:
H01S 500
US Classification:
372 50, 369 4412, 369 4414, 369 4437, 36911201, 36911214, 36911229, 369121
Abstract:
A VCSEL-based monolithic optical pickup system for use with optical recording media with a retaining member, a plurality of VCSELs disposed on the retaining member for emitting laser beams, a plurality of detectors disposed on the retaining member for receiving reflected laser beams, and a stepped micro-mirror for reflecting laser beams emitted by the plurality of VCSELs toward optical recording media and for reflecting laser beams reflected from the recording media toward the plurality of detectors. The VCSELs and detectors can be disposed in laser/detector pairs wherein each detector surrounds its respective VCSEL. The system can incorporate upstanding VCSELs each with a sloped and mirrored side surface and with a detector disposed adjacent to the side surface whereby a laser beam emitted by the VCSEL can be directed to an optical recording media, then reflected from the optical recording media onto the side surface of the VCSEL, and then reflected by the side surface of the VCSEL onto the detector adjacent to the side surface of the VCSEL.

US Patent:
6882669, Apr 19, 2005
Filed:
Feb 11, 2002
Appl. No.:
10/073716
Inventors:
Zhijiang Hang - Lexington MA, US
Victor Lazarev - Burlington MA, US
International Classification:
H01S005/00
US Classification:
372 43, 372 45, 372 46, 438 25, 438459
Abstract:
High powered lasers of substantially any wavelength produced by certain processes including the process of providing a structure comprising a substrate with an epi structure thereon comprising a gain region with multiple quantum wells, a mirror stack coupled to the gain region, and a conductive layer coupled to the mirror stack; dividing the conductive layer into a conductive, central area and one or more dielectric, peripheral areas; attaching a conductive plate to the conductive layer; thinning the substrate to improve the passage of light therethrough to produce a substrate remnant; and attaching an electrode to the substrate remnant.

Method And Device For Skin Treatment With Replaceable Photosensitive Window

View page
US Patent:
7837675, Nov 23, 2010
Filed:
May 31, 2005
Appl. No.:
11/141370
Inventors:
Jeffrey S. Dover - Newton MA, US
Victor Lazarev - Burlington MA, US
Daniel Lawrence Roth - Boston MA, US
Assignee:
Shaser, Inc. - Woburn MA
International Classification:
A61B 18/18
US Classification:
606 9, 606 2, 607 88, 607 89
Abstract:
A method for the treatment of skin including the steps of determining the skin depth for energy absorption necessary for treatment; and generating a spot size for energy impinging on the skin to provide a desired amount of energy to the desired depth for treatment. In one embodiment the selected spot size has a small diameter. In another embodiment the spot diameter is narrower than the spacing between adjacent hairs on the skin. In another aspect the invention relates to an apparatus for the treatment of skin including a source of energy; and a means for selecting a spot size for energy from the source impinging on the skin to provide a desired amount of energy to a desired depth for treatment. In another embodiment the apparatus includes an interlock to prevent the laser from producing light unless the source is positioned to irradiate only the skin.

Scanning Laser System For The Treatment Of Tissue

View page
US Patent:
8246612, Aug 21, 2012
Filed:
Sep 5, 2007
Appl. No.:
12/375862
Inventors:
Victor Lazarev - Billerica MA, US
Doug Ely - North Andover MA, US
Daniel Roth - Newton MA, US
Assignee:
Shaser, Inc. - Lexington MA
International Classification:
A61B 18/20
US Classification:
606 9, 607 88, 607 90
Abstract:
The disclosed technology can be embodied within optical heads or other optical systems adapted for providing a selected dermatologic treatment (e. g. , temporary hair growth management). This technology uses a scanner to mechanically change an orientation of an optical element, such as a light pipe, to facilitate the conveyance of light energy to multiple target/treatment locations on a patient's skin.

Power Supply For Light-Based Dermatologic Treatment Device

View page
US Patent:
8317781, Nov 27, 2012
Filed:
Feb 13, 2012
Appl. No.:
13/371540
Inventors:
William Owens - Framingham MA, US
Arthur Aaron - Arlington MA, US
Douglas Ely - North Andover MA, US
Bikram Yonjan - Somerville MA, US
Victor Lazarev - Billerica MA, US
Assignee:
Shaser, Inc. - Lexington MA
International Classification:
A61B 18/18
US Classification:
606 9, 606 10, 606 13, 606 17, 607 88, 607 89
Abstract:
Switching power supplies made in accordance with the disclosed technology drive flash lamps of dermatologic treatment devices to emit a sequence of relatively small light pulses that are aligned with particular locations within the waveform of the AC line source. Such power supplies not only enable sufficient light energy in aggregate to therapeutically heat target chromophores in a skin region without causing undesired damage to surrounding tissue, but also provide the added benefit that the corresponding electrical energy need not be substantially drawn from any charged capacitor. The disclosed power supply further compensates for performance degradation of the flash lamps during their usable life, by modifying its operation based on predetermined values that are indicative of flash lamp aging/efficiency characteristics. The flash lamps and their associated stored values are preferably incorporated into a replaceable cartridge that facilitates user maintenance of the dermatologic treatment device.
