PROJECT TITLE :

Theoretical Analysis and Experimental Validation of Sampling Volume in Tilted Imaging System

ABSTRACT:

A method for accurately calculating the sampling volume in a tilted imaging system is proposed. 2 sorts of tilted imaging systems are investigated, i.e., Kind I (solely the thing plane is inclined to the optical axis) and Type II (both the item plane and also the image plane are inclined to the optical axis). Primarily based on geometrical optics, the sampling volumes of these two types of tilted imaging systems have been simulated. Compared with the central magnification of an imaging system and therefore the focal length and $F$-variety of the imaging lens, the impact of the tilted angle of the article plane on the sampling volume is decided to be more important. A tilted imaging experimental setup has been established, calibration plate images at various tilted angles and positions are acquired, and also the sampling volume has been obtained by image processing. The experimental results are in terribly smart agreement with the theoretical predictions. Because the tilted angle will increase, for the Kind-I system, the sampling volume increases, whereas for the Type-II system, the sampling volume decreases. In addition, the sampling volume of the Type-II system is larger than that of the Kind-I system. Data of the sampling volume is important in many quantitative applications of tilted imaging systems.
