Title: Thomas Per Krister Martinsson and a Patent for Height Measurement
Introduction
Thomas Per Krister Martinsson is an inventor associated with Veldhoven, the Netherlands, and ASML Netherlands B.V. His patent work includes a sensor design for determining focus position through periodic signals.
Latest Patents
Martinsson is associated with 1 patent: “Height Measurement Sensor Using Derivative of Periodic Points.” The invention describes a sensor with a projection unit that directs radiation onto a surface and a detection unit that measures the reflected radiation through a detection grating. A controller analyzes periodic components in the detector’s output signal, compares two points separated by a period, and determines the sensor’s focus plane when the derivative changes sign.
Career Highlights
The patent reflects work on optical sensing and focus-plane measurement. Its approach uses the behavior of a periodic detector signal to identify the focus position.
Collaborations
Martinsson is associated with ASML Netherlands B.V. His listed coworker is Mihaita Popinciuc.
Conclusion
Thomas Per Krister Martinsson’s patent describes an optical height-measurement sensor that uses periodic signal analysis to determine its focus plane.
