where theta is the angular field of view. This formula lets you figure out the angle of view of the camera. Let’s take an example :What is your working distance to get an 10″ field of view with a 50mm lens on a linescan camera with array length 0.6″? This is the approximate w...
What is the distance of the center of each mask zone from the mirror's center? If the innermost zone is at the mirror's center, what is the diameter of the zone? Are you using a fixed source tester? You had mentioned you might try that. Making a guess at the mask openings and a...
an axis of rotation oriented parallel to the beam direction and on which the optical elements are arranged along a partial circle. Accordingly, by turning the exchange wheel by a rotational angle corresponding to the arc distance between two optical elements on the partial circle, two elements in...
corresponding to the workpiece curvature 𝜌𝑠ρs with the unit of 𝑃𝑎Pa; 𝑆Ω𝑡SΩt is the area of the contact region corresponding to 𝑃𝑡Pt, which sets the dimension unit as 𝑚2m2; and 𝑐𝑡ct is the distance between the regional center of 𝑆Ω𝑡SΩt and the ...
