  • Patent number: 10365298
    Abstract: A detection arrangement and method for directing the sensitivity of an optical knife-edge detection system to its optimal operating point. This is referred to as an increase in the detection dynamic range of the system with advantageous applications for detecting motion of a surface such as for Atomic Force Microscopy as well as detecting acoustic vibrations on unstable surfaces. A pair of parallel reflecting surfaces, such as an optical slab waveguide, serve to reflect the sensing beam back onto the knife-edge detector once it is shifted off its sensing range. Allowing multiple reflections, the sensing beam is maintained on the knife-edge detector even at large angular offsets from the optimal operating point of the basic knife-edge detector. Use of a modified arrangement, with two knife-edge detectors at quadrature ensures near-optimal sensitivity at a detection dynamic range up to forty-fold larger than that of the basic knife-edge system.

A path of a detector beam (AB) is overlapped with one of the trapping beams (TB3), wherein the detector beam has a distinct wavelength (?A) from that of the overlapping trapping beam (TB3). In one channel, the light from the sample volume is filtered according to wavelength, and only the filtered light having the wavelength (?A) of the detector beam (AB) is measured.

  • Patent number: 9864934
    Abstract: The optical scanning device includes a storage unit configured to store information on a scanning time of laser light and an emitted position of the laser light in a sub-scanning direction, the laser light measured on a plane. A scanning time for forming one scanning line is set based on the information on the measured scanning time and the measured emitted position, which is stored in the storage unit, and a radius of a photosensitive drum. This allows a magnification error in a main scanning direction to be reduced with an inexpensive configuration while realizing downsizing of an apparatus.

  • Patent number: 9864140
    Abstract: In part, the invention relates to optical caps having at least one lensed surface configured to redirect and focus light outside of the cap. The cap is placed over an optical fiber. Optical radiation travels through the fiber and interacts with the optical surface or optical surfaces of the cap, resulting in a beam that is either focused at a distance outside of the cap or substantially collimated. The optical elements such as the elongate caps described herein can be used with various data collection modalities such optical coherence tomography. In part, the invention relates to a lens assembly that includes a micro-lens; a beam director in optical communication with the micro-lens; and a substantially transparent film or cover. The substantially transparent film is capable of bi-directionally transmitting light, and generating a controlled amount of backscatter. The film can surround a portion of the beam director.

  • Patent number: 9739595
    Abstract: A multi-dimensional measuring system is disclosed wherein a laser-based tracking unit communicates with an optical target on a measurement instrument to obtain position and orientation information about the instrument. The optical target incorporates a plurality of encoders configured to provide a full 360° working range in pitch, yaw and roll. Full working range in pitch and yaw is achieved through the use of a pitch/yaw angular encoder. Full 360° working range in roll is achieved with a combination of a level sensor and a 360° angular encoder, which are fixed to a pendulum so that the level sensor is always aligned to gravity. Use of a slip-ring mechanism ensures the unlimited full working range in roll. The measurement instrument includes a scanner integrated with a probe receptacle adapted to accept a probe assembly to provide the instrument with both a scanning measurement and a probe measurement capabilities.
