Abstract: Disclosed is a position system and method for correcting the position of a workpiece during a manufacturing process. The system includes a light generating means for projecting a light beam onto the top surface of the workpiece at a predetermined angle and a video capturing means for detecting the light received by the workpiece. The light projected on the workpiece is scanned to determine the deviation direction and the deviation amount from a predetermined reference point, then the position of the work piece is adjusted based on a positional relationship between a digital image of the projected light on the surface of said workpiece and the predetermined reference image.

Abstract: A fluid flow monitoring device. A laser source produces a laser beam having a beam frequency that is transmitted through an optical fiber and absorbed in a small quantity of thermally conductive material having high optical absorption at the beam frequency. A temperature sensor is embedded in the light absorbing material. The light absorbing material is placed in a fluid flow and the light absorbing material is heated with energy in the laser beam. Voltage produced by the temperature sensor is monitored as an indication of the fluid flow. The flow-measuring device can be made extremely unintrusive using very thin temperature sensor wire and very thin optical fiber, both of which are contained within a very thin probe. The device is calibrated under known flow conditions. The flowing fluid cools the material. Using the calibration information, speed of the flowing fluid is determined by measuring the voltage produced by the temperature sensor.

Abstract: The invention describes a method for measuring a property of a sample by: 1) irradiating a portion of the sample with an excitation pattern characterized by at least one spatial phase and spatial period; 2) diffracting a portion of a probe beam off a surface of the sample; 3) detecting the diffracted portion of the probe beam with an optical detector to generate a light-induced signal; 4) adjusting the spatial phase of the excitation pattern; 5) repeating the irradiating, diffracting and detecting steps to generate an additional light-induced signal; and 6) processing the light-induced signals to determine a property of the sample.

Abstract: A device for evacuating plume products. A gas is forced through at least one compressed gas jet nozzle which directs a compressed gas flow toward an evacuation orifice. A vacuum system provides a vacuum at said evacuation orifice sufficient to provide a vacuum mass flow rate substantially greater than said compressed gas mass flow rate so that the plume products are entrained in gas exiting said gas jet nozzles and evacuated along with the gas through the evacuation orifice. In one embodiment, compressed gas may be cooled to produce aerosol particles to further improve collection efficiency and produce beneficial therapeutic effects. The device is especially useful in laser surgery to evacuate ablation products in plumes created by pulse lasers.

Abstract: A scheme for monitoring the performance of a gas-phase filter in which upstream and downstream detection surfaces are exposed to upstream and downstream air so that molecular contamination may respectively form non-volatile residue thereon, and the performance of the air filter is determined based on the ratio of the amount of non-volatile residue respectively forming on the upstream and downstream detection surfaces. In another embodiment, a first electrical signal is provided representative of the amount of non-volatile residue forming on the upstream detection surface, a second electrical signal is provided representative of the amount of non-volatile residue forming on the downstream detection surface, and the performance of the air filter is determined in real-time based on the first and second electrical signals that are provided.

Abstract: A device for evacuating ablation products of tissue ablated with a pulse laser beam. A gas is forced through at least one compressed gas jet nozzle. An evacuation nozzle is spaced apart from the compressed gas jet nozzle and a pulse laser beam passes in between the jet nozzle and the evacuation nozzle to illuminate and ablate tissue. A vacuum system provides a vacuum at the evacuation nozzle sufficient to provide a vacuum mass flow rate substantially greater than the compressed gas mass flow rate so that the products of the ablation are entrained in gas exiting the gas jet nozzles and evacuated along with the gas through the evacuation nozzle.
