Samsung patents laser device that creates multiple images from one pulse

Patent drawing
Patent drawing from the official filing.

Samsung describes an optical imaging device that uses a laser to create a broadened pulse of light. This single pulse hits a target object, and the reflected light is used to generate a set of spectral images.

Why it mattersThis technology could improve how devices capture detailed color or chemical information from a single light flash, which is useful for scientific or industrial inspection tools.

In the filing’s own words

An optical imaging device includes a pulse generator including a pulse generating device configured to generate pulse lasers and a pulse expander configured to receive a pulse laser from the pulse generating device, and generate a broadened pulse laser by expanding a spectrum and width of the received pulse laser, an optical assembly including an objective lens configured to receive the broadened pulse laser and pass the received broadened pulse laser to a target object, and a light receiver including a light receiving device configured to receive a reflected pulse laser corresponding to the broadened pulse laser reflected from the target object and convert the reflected pulse laser into an electrical signal, and at least one processor configured to generate a spectral image set based on the electrical signal generated by the light receiving device.

What exactly they claim (claim 1)

1. An optical imaging device comprising: a pulse generator comprising: a pulse generating device configured to generate pulse lasers; and a pulse expander configured to: receive a pulse laser from the pulse generating device; and generate a broadened pulse laser by expanding a spectrum and width of the received pulse laser; an optical assembly comprising an objective lens configured to: receive the broadened pulse laser and pass the received broadened pulse laser to a target object; and a light receiver comprising: a light receiving device configured to: receive a reflected pulse laser corresponding to the broadened pulse laser reflected from the target object; and convert the reflected pulse laser into an electrical signal; and at least one processor configured to generate a spectral image set based on the electrical signal generated by the light receiving device, the spectral image set comprising a plurality of spectral images generated based on one reflected pulse laser received by the light receiving device.
