摘要:
The invention relates to an optical element for guiding and forming a laser beam, and to a method for recording beam parameters, particularly in a laser system, comprising a carrier substrate (40) and a coating (39), which is applied to at least one side of the carrier substrate (40), and comprising at least one temperature sensor (38). The temperature sensor (38) is comprised of a number of pixels arranged in a matrix, and each respective pixel has at least one temperature-sensitive element (39). The at least one temperature-sensitive element (39) of the pixel is constructed inside the carrier substrate (40) made of silicon.

摘要:
The three-dimensional structure of the surface of a cavity is reconstructed. The cavity can be the outer ear canal of a person. A probe with an optical sensor is introduced into the cavity to produce video signals, which are transmitted to a computer device. The computer device transforms the video signals into position data representing the surface of the cavity, thereby defining the three-dimensional structure of the cavity.
