Title: Kristofer E Tvedt: Innovator in Optical Sensor Calibration
Introduction
Kristofer E Tvedt is a notable inventor based in Tucson, AZ, who has made significant contributions to the field of optical sensor calibration. His innovative work focuses on enhancing the efficiency and effectiveness of testing optical sensors, particularly in military applications.
Latest Patents
Tvedt holds a patent for a "Fixed-source array test station for calibration of a semi-active laser (SAL) seeker." This invention provides a cost-effective, high-throughput test bed for testing optical sensors that require stimulus at fixed angular positions. The SAL seeker necessitates stimulus at fixed angular positions across its field of view (FOV) to calibrate its spatial transfer function (STF). The design features an array of fixed collimated sources aligned to overlap the entrance pupil of the sensor under test. Each source can consist of inexpensive light-emitting diodes (LEDs) or vertical cavity surface-emitting lasers (VCSELs) paired with collimators. To facilitate alignment, the sources are positioned on and perpendicular to the surface of a sphere, with the seeker's entrance pupil located at the center. The sources are activated according to a specific activation profile to calibrate or test the sensor effectively.
