Tracking Rotation and Translation of Laser Microsurgical Instruments
An accurate optical sensing system has been developed to measure the position and orientation of a laser beam in two dimensions. The system is useful for evaluation of the accuracy of hand-held laser microsurgical instruments. The apparatus uses a lens and a beam-splitter to receive the incoming laser beam. Two position sensitive detectors placed at different distances from the beam splitter ma...
متن کاملNovel Method of Detecting Movement of the Interference Fringes Using One-Dimensional PSD
In this paper, a method of using a one-dimensional position-sensitive detector (PSD) by replacing charge-coupled device (CCD) to measure the movement of the interference fringes is presented first, and its feasibility is demonstrated through an experimental setup based on the principle of centroid detection. Firstly, the centroid position of the interference fringes in a fiber Mach-Zehnder (M-Z...
متن کاملNumerical Investigation of the Non-Uniformity of the Electric Field Distribution by Injection of Net Electron Charge in TE CO2 Laser
In this report, the distribution and deviation of electric field in the active medium of the TE CO2 laser has been investigated due to the injection of net electron charge beam as a plasma generator. Some parameters of system have been considered, such as density and mean-free-path of injected charge beam. The electric potential and electric field distribution have been simulated by solving the...
متن کاملRapid and Reliable Calibration of Laser Beam Deflection System for Microcantilever-Based Sensor Setups
Cantilever array-based sensor devices widely utilise the laser-based optical deflection method for measuring static cantilever deflections mostly with home-built devices with individual geometries. In contrast to scanning probe microscopes, cantilever array devices have no additional positioning device like a piezo stage. As the cantilevers are used in more and more sensitive measurements, it i...
متن کاملPretreatment quality control of single isocenter half- beam treatment planning technique using an amorphous silicon electronic portal-imaging device (EPID)
Introduction: Electronic portal imaging devices (EPIDs) are fundamentally used for instantaneous verification of the patient set‐up, block shape, and leaf positions during radiation therapy. In radiotherapy, situations arise in which an inclined PTV must be treated mutually with adjacent nodal regions. This methodology is most widely used for matching tangential/lateral breas...
