Increase resolution with a simple configuration. [Solution] The imaging device (1) includes a first laser light source (11) that emits a first laser beam (L1), a second laser light source (12) that emits a second laser beam (L2), a zoom lens (13) that can switch between a first focal length (f1) and a second focal length (f2), and a sensor (14) that detects reflected light from an object (2) irradiated with the first laser beam (L1) or the second laser beam (L2) through the zoom lens (13). The second focal length (f2) is longer than the first focal length (f1). When the focal length of the zoom lens (13) is the first focal length (f1), the first laser light source (11) is positioned to satisfy the Scheinproof condition. When the focal length of the zoom lens (13) is the second focal length (f2), the second laser light source (12) is positioned to satisfy the Scheinproof condition.

This invention relates to the field of automotive braking technology, and specifically to a method for analyzing braking noise in an automotive braking system. The method comprises the following steps: S1: Obtaining the rotational stiffness of the brake pads during braking; S2: Establishing a 1D model of the automotive braking system based on the rotational stiffness of the brake pads to obtain the relative angular velocity between the brake disc and brake pads during the complete braking process; S3: Dividing the relative angular velocity interval between the brake disc and brake pads during the complete braking process into n equal intervals; S4: Establishing a 3D analysis model of the automotive braking system's braking noise based on the stick-slip effect between the brake disc and brake pads, based on the interval division of the relative angular velocity; S5: Obtaining the results of the braking noise analysis of the automotive braking system based on the stick-slip effect between the brake disc and brake pads during the complete braking process; S6: Verifying and correcting the 1D model of the automotive braking system and the 3D simulation analysis model of the automotive braking system's braking noise based on actual experimental results.

A method includes obtaining a first imaging scan and a second imaging scan of a single subject's brain. The first imaging scan is converted to a first data set and the second imaging scan is converted to a second data set. A sequence-adaptive multi-modal segmentation algorithm is applied to the first data set and the second data set. The sequence-adaptive multi-modal segmentation algorithm performs automatic intensity-based tissue classification to generate a first labeled data set and a second labeled data set. The first labeled data set and the second labeled data set are automatically co-registered to one another to generate a transformation matrix based on the first labeled data set and the second labeled data set. The transformation matrix is applied to align the first data set and the second data set.
