Publication number: 20040125361Abstract: An agile optical beam profiler using a two-dimensional small tilt digital micromirror device/chip, a translation stage, and single photodetector or pair of photodetectors. A method of profiling an optical beam includes positioning a programmable spatial light modulator in an incident optical beam and sequentially moving the spatial light modulator to at least one position in a first planar direction in a displacement increment less than a pixel width of the spatial light modulator. The method also includes directing respective portions of the optical beam to a photodetector at each position of the spatial light modulator. The method may also include calibrating the photodetectors by directing a portion of the beam to the photodetector, then directing the entire beam, or a remaining portion of the beam, to the photodetector, and normalizing the detected power of the portion with the detected power of the entire beam, or remaining portion, respectively.Type: ApplicationFiled: September 8, 2003Publication date: July 1, 2004Inventors: Nabeel Agha Riza, Muhammad Junaid Mughal

Publication number: 20040125363Abstract: The invention relates to a portable refractometer comprising a depression (7) for samples, located on an insertion tip (11) in such a way that once the insertion tip (11) has penetrated a liquid or a fruit, a sufficient quantity of the sample liquid remains in the depression (7) for samples, thus wetting a measuring surface (4) that is delimited in said depression by a transparent body. The refractive index of the wetting liquid can be determined by measuring the intensity of an optical beam that is reflected by the measuring surface (4).Type: ApplicationFiled: November 3, 2003Publication date: July 1, 2004Inventors: Markus Langenbacher, Andreas Derr, Frank Eder

Publication number: 20040125364Abstract: In an angle detecting apparatus and projector using range finder units, range finding calculations are performed in plural directions using line type passive range finders as the range finding units. An average value of inclination angles calculated based on the range finding calculations is selected as the inclination angle. Thus, if one range finding result has an abnormal value, the adverse effects thereof are reduced and the structure is miniaturized.Type: ApplicationFiled: August 29, 2003Publication date: July 1, 2004Inventor: Shiroshi Kanemitsu
