IMAGE ACQUISITION APPARATUS, IMAGE ACQUISITION METHOD, AND MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240137637 titled 'IMAGE ACQUISITION APPARATUS, IMAGE ACQUISITION METHOD, AND MEDIUM

Simplified Explanation

The apparatus described in the abstract is a device for acquiring an image of a phase object using two different light sources and a telecentric optical system. Here is a simplified explanation of the patent application:

• The apparatus includes a first light irradiation unit that shines parallel light on the subject, a second light irradiation unit that shines light at a different angle, an imaging lens with a telecentric optical system, and an imaging unit that captures the image of the subject illuminated by the lights.
• The optical axis of the imaging lens is parallel to the optical path of the first light, and the imaging unit is positioned opposite to the first light irradiation unit with respect to the subject.
• An optical path length adjusting unit controls the distance between the telecentric optical system and the subject.

Original Abstract Submitted

an apparatus acquiring an image of a subject of a phase object includes: a first light irradiation unit irradiating the subject with a parallel light as a first light; a second light irradiation unit irradiating the subject with a second light at an incidence angle different from that of the first light irradiation unit; an imaging lens having a telecentric optical system; and an imaging unit which images the subject irradiated with at least one of the first light and the second light through the imaging lens, wherein the optical axis of the imaging lens is parallel to an optical path of the first light irradiation unit, the imaging unit is arranged on the optical axis opposite to the first light irradiation unit to the subject, and an optical path length adjusting unit controlling the distance between the telecentric optical system and the subject on the optical axis is arranged.
