Abstract: A system for determining the profile of a laser beam includes a detector having a thermochromic liquid crystal film (TLCF) in thermal communication with a heat spreader and a thermoelectric cooler. The liquid crystal film has a thermochromic response such that heating of the film by a received laser beam creates a detectable color response at the film. The system also includes an image sensor and a controller configured to output an operating current for the TEC and receive images from the sensor. The system can selectively vary the temperature set point of the TEC to change the steady state temperature of the TLCF to examine the full intensity profile of the received beam even when the temperature response bandwidth of the TLCF is too narrow to display the full beam profile in a single color spot.

Abstract: Various embodiments and methods relating to an optical fiber alignment and splicing system are described herein. The optical fiber alignment and splicing system includes a first rotation stage having a first central axis, a first end, and a second end, and a second rotation stage having a second central axis, a third end, and a fourth end. The first central axis extends from the first end to the second end of the first rotation stage, and the second central axis extends from the third end to the fourth end. The first rotation stage includes a first optical fiber channel extending from the first end of the first rotation stage to the second end of the first rotation stage, and the second rotation stage includes a second optical fiber channel extending from the third end of the second rotation stage to the fourth end of the second rotation stage.

Abstract: Various embodiments and methods related to an optical fiber alignment system are provided herein. The optical fiber alignment system includes a controller and a rotation stage having a central axis, a first end, and a second end. The central axis extends from the first end to the second end of the rotation stage. The rotation stage includes an optical fiber channel extending from the first end of the rotation stage to the second end of the rotation stage and may be operationally coupled with the controller. The rotation stage is configured to rotate about the central axis of the rotation stage. The optical fiber alignment system includes a light source positioned to emit light onto the optical fiber channel at an oblique angle from the central axis of the rotation stage. The optical fiber alignment system includes an image sensor positioned adjacent to the second end of the rotation stage.
