Abstract: A method for profiling a laser beam includes receiving the laser beam at a thermochromic interface of a detector. A temperature set point for the detector can be selected. The temperature set point can correspond to an equilibrium temperature at the thermochromic interface. The method can also include capturing an image of the thermochromic interface and using the image to determine a partial intensity profile corresponding to at least a portion of the beam intensity profile. A reconstructed beam profile can be assembled using the partial intensity profile. If the reconstructed beam profile is not complete, the method can include iterating over additional temperature set points to determine additional partial intensity profiles. The method can also include determining that the reconstructed beam profile is complete and outputting the reconstructed beam profile.

Abstract: A grip cleaning and rising devices includes a dual tubular body having a closed lower end for holding separately both soapy and rinsing fluid, and an open upper end for receiving the grips or handles to be cleaned longitudinally therein. Cleaning is effected by a single helical brush with multiple turns that is simply threaded into position in the washing body. A splash guard is also provided as an impinging lip that extends into the receiving orifice. A smaller diameter rinsing tube is in fluid isolation from the cleaning solution. A cap may optionally be provided to close the top of the grip washer when not in use or for transportation from one place to another. The simple tubular construction enables the grip washer adapted for use as a mobile unit, with a laterally extending base to allow the user to stabilize the device by placing his or her feet over the base edge.
