AI Technical Summary
Technical Problem
Conventional three-dimensional imaging systems face complications in adjusting mirrors and actuators to maintain resolution, especially under vibration, leading to deteriorated performance.
Method used
Employing a first and second slit light source with a zoom lens capable of switching between two focal lengths, where each slit light source satisfies the Scheinproof condition at its respective focal length, allowing fixed orientations and positions of light sources and sensors, and using an analysis device for three-dimensional measurement.
Benefits of technology
This configuration maintains resolution and improves image quality with a simpler setup, enhancing resistance to vibrations and accuracy of measurements.

Abstract
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.
