IMAGE ACQUISITION APPARATUS, IMAGE ACQUISITION METHOD, AND MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18486200 titled 'IMAGE ACQUISITION APPARATUS, IMAGE ACQUISITION METHOD, AND MEDIUM
Simplified Explanation
The apparatus described in the patent application is designed to acquire an image of a phase object by irradiating the subject with two different lights at different angles and then imaging the subject using a telecentric optical system.
- The first light irradiation unit emits parallel light onto the subject.
- The second light irradiation unit emits light at a different angle than the first unit.
- The imaging lens has a telecentric optical system.
- The imaging unit captures images of the subject illuminated by either the first or second light.
- The optical axis of the imaging lens is parallel to the optical path of the first light.
- The imaging unit is positioned opposite to the first light irradiation unit on the optical axis.
- An optical path length adjusting unit controls the distance between the optical system and the subject.
Potential Applications
This technology could be used in medical imaging, material science, and quality control applications where precise imaging of phase objects is required.
Problems Solved
This technology solves the problem of accurately imaging phase objects by using multiple light sources and a telecentric optical system.
Benefits
