摘要: An apparatus for obtaining an image of a tooth having at least one light source providing incident light having a first spectral range for obtaining a reflectance image (122) from the tooth and a second spectral range for exciting a fluorescence image (120) from the tooth. A polarizing beamsplitter (18) in the path of the incident light from both sources directs light having a first polarization state toward the tooth and directs light from the tooth having a second polarization state along a return path toward a sensor (68), wherein the second polarization state is orthogonal to the first polarization state. A first lens (22) in the return path directs image-bearing light from the tooth toward the sensor (68), and obtains image data from the portion of the light having the second polarization state. A long-pass filter (15) in the return path attenuates light in the second spectral range.

摘要: A method is disclosed for making deep microstructures in photoresist. The method utilizes a pool of photoresist on top of a transparent substrate and the laser is located below the substrate. Structures are created in the photoresist by transmitting the laser light through the substrate up into the photoresist. Since the photoresist does not have to be spin coated onto the substrate, very thick layers of photoresist can be used while the thickness uniformity is determined by the substrate surface. Alternately, a contoured substrate can be used while producing uniform structures.

摘要: A tissue imaging system (200) for examining the medical condition of tissue (290) has an illumination optical system (205), which comprises a light source (220), having one or more light emitters, beam shaping optics, and polarizing optics. An optical beamsplitter (260) directs illumination light to an imaging sub-system, containing a spatial light modulator array (300). An objective lens (325) images illumination light from the spatial light modulator array to the tissue. An optical detection system (210) images the spatial light modulator to an optical detector array. A controller (360) drives the spatial light modulator to provide time variable arrangements of on-state pixels. The objective lens operates in a nominally telecentric manner relative to both the spatial light modulator and the tissue. The polarizing optics are independently and iteratively rotated to define variable polarization states relative to the tissue. The modulator pixels optically function like pinholes relative to the illumination light and the image light.

摘要: A method for fabricating a mold tool for molding optical elements is taught which comprises heating a mold tool blank made from a vitreous material to a temperature above the glass transition temperature of the vitreous material; generating an axial viscosity gradient in the mold tool blank; pressing a punch into an optical quality mold surface of the mold tool blank, the punch including a pressing surface with a predetermined geometry for forming an optical feature; cooling the mold tool blank to a temperature below the glass transition temperature of the material; and removing the punch from the mold tool blank thereby creating the optical feature in the optical quality mold surface. The axial viscosity gradient is achieved by creating an axial thermal gradient. Multiple optical features can be formed in the mold surface of the blank using a single punch such that the pressing, cooling and removing steps are repeated with the punch or the blank being translated to a different position between the last removing step and the next pressing step. In such manner, a high temperature glass mold tool can be formed which can be used to mold glass optical elements either individually or in arrays.

摘要: A method for displaying live video of a tooth identifies a tooth tissue region in a viewable image frame obtained from a video stream and processes pixel data within the tooth tissue region to identify a suspected caries site. Intensity values for pixels that correspond to the suspected caries site are modified and a highlighted viewable image frame is formed as a combination of the modified intensity values corresponding to the suspected caries site and other pixel values in the viewable image frame. The highlighted viewable image frame is displayed in video form.
