Disclosed herein are optical assemblies having thin, low profile shapes. These optical assemblies may be used with fiber coupled lasers and other light sources, including high power sources, to irradiate tissue at a wavelength suitable for inducing ablation or coagulation to a target depth, denaturation, thermal modification of a tissue, and/or preferential injury to a target tissue structure. Example optical assemblies can produce substantially uniform illumination patterns that are useful for treating superficial tissue, including the internal or luminal (e.g., esophageal) tissue. Some examples may have capability for cooling superficial tissue or skin, such as a detachable, reusable heat sink for active cooling without consumables, fluid pumps, or other cooling equipment.

Low profile apparatus and method for phototherapy

An apparatus and a method are provided for the treatment of soft tissue. The apparatus includes a light source and at least two optical assemblies. Each of the optical assemblies includes at least one optical element and a light-transmitting contact surface configured to transmit a substantially uniform distribution of light therethrough. The apparatus further includes at least two optical transmission devices each disposed between the light source and a corresponding one of the at least two optical assemblies. The apparatus also includes a handpiece to which the at least two optical assemblies are attached, and which is adapted to bring the light-transmitting contact surfaces of the at least two optical assemblies in contact with soft tissue disposed therebetween. The method includes compressing and substantially flattening portions of the tonsil tissue between light-transmitting contact surfaces of two opposed light emitting optical assemblies, introducing light into an optical element of each of the optical assemblies; and irradiating the tonsil tissue by directing the light from the optical element through the light-transmitting contact surfaces to the tonsil tissue in a substantially uniform light distribution.

Photothermal treatment of soft tissues

Imaging systems, imaging device analysis systems, imaging device analysis methods, and light beam emission methods are described. According to one aspect, an imaging device analysis method includes receiving initial light comprising a plurality of wavelengths of light, filtering some of the wavelengths of the initial light forming a plurality of light beams comprising different wavelengths of light, after the filtering, optically communicating the light beams of the different wavelengths of light to an imaging device, receiving the light beams using the imaging device, and analyzing the imaging device using light, wherein the light beams comprising the different wavelengths of light are emitted beams after the receiving.

A focusing arrangement has a lens disposed adjacent a lamp, a sensor for detecting a parameter which varies with a focal position of light focused by the lens, and a controller for adjusting the position of the lens based upon an output from the sensor in a manner which modifies the focal position of the light by the lens and maximizes the parameter detected by the sensor.

Focusing arrangement

A method for projecting an image with a projection system includes zooming a projected image in accordance with a resolution of the image, when a resolution of the image is less than a resolution corresponding to the projection system. A projection system for projecting an image based on a received video signal including optics having a corresponding resolution and a zoom control controlling a zoom of the optics. If a resolution of the image of the video signal is less than the resolution corresponding to the optics, the zoom control zooms a projected image.
