Each pulse can have a square-wave configuration, whereby each pulse can be time-gated to facilitate discarding the leading edge and the trailing edge (and associated non-linear effects) of each pulse and accordingly, capture of the central portion of the pulse from which the Doppler-shifted frequency, and ultimately, the vibration frequency of the target can be determined. Determination of the vibration velocity facilitates identification of the target being in a state of motion.

  • Patent number: 9761492
    Abstract: A processing method for optical device wafers includes a shielded tunnel forming step and a dividing step. In the shielded tunnel forming step, a sapphire substrate is irradiated with a pulse laser beam having such a wavelength as to be transmitted through the sapphire substrate along regions corresponding to planned dividing lines. The light focus point of the beam is positioned inside the substrate from the back surface side of the substrate. Fine pores and amorphous regions that shield the fine pores form shielded tunnels along the planned dividing lines. In the dividing step, an external force is applied to the optical device wafer, and the optical device wafer is divided into individual optical device chips along the planned dividing lines. In the shielded tunnel forming step, a spherical aberration is generated by causing the laser beam to be incident on a condensing lens with a divergence angle.

  • Patent number: 9646898
    Abstract: Techniques herein include systems and methods that provide a spatially-controlled or pixel-based projection of light onto a substrate to tune various substrate properties. A given pixel-based image projected on to a substrate surface can be based on a substrate signature. The substrate signature can spatially represent non-uniformities across the surface of the substrate. Such non-uniformities can include energy, heat, critical dimensions, photolithographic exposure dosages, etc. Such pixel-based light projection can be used to tune various properties of substrates, including tuning of critical dimensions, heating uniformity, evaporative cooling, and generation of photo-sensitive agents. Combining such pixel-based light projection with photolithographic patterning processes and/or heating processes improves processing uniformity and decreases defectivity. Embodiments can include using a digital light processing (DLP) chip, grating light valve (GLV), or other grid-based micro projection technology.

  • Patent number: 9592158
    Abstract: Systems and methods for removing an epithelial layer disposed over a stromal layer in a cornea irradiate a region of the epithelial layer with a pulsed beam of ablative radiation. The ablative radiation is scanned to vary the location of the beam within the region in accordance with a pulse sequence. The pulse sequence is arranged to enhance optical feedback based on a tissue fluorescence of the epithelial layer. The penetration of the epithelial layer is detected in response to the optical feedback. The use of scanning with the pulse sequence arranged to enhance optical feedback allows large areas of the epithelium to be ablated such penetration of the epithelial layer can be detected.
