Sony patents camera system that tracks particles at different depths

Sony has filed a patent for an analysis system that uses a specific arrangement of lenses and mirrors to capture images of particles moving through a fluid channel. The design allows light from particles at different positions to be focused onto distinct reflective surfaces, helping the system gather detailed optical data.

Why it mattersThis technology could improve how scientists or engineers analyze microscopic samples by allowing a single optical setup to handle particles at varying depths.

In the filing’s own words

An analysis system includes an optical system that guides light from a particle flowing in a flow channel to an image sensor, in which the optical system includes an objective lens facing the flow channel, an additional objective lens that forms an image of light passing through the objective lens, and a mirror that reflects light from the additional objective lens toward the additional objective lens, light from the particle passing through a different position in the flow channel passes through the objective lens and the additional objective lens, and then is focused at a different image forming position, and the mirror has a plurality of reflective surfaces respectively positioned at different image forming positions.

What exactly they claim (claim 1)

1. An analysis system comprising: an optical system that guides light from a particle flowing in a flow channel to an image sensor, wherein the optical system includes an objective lens facing the flow channel, an additional objective lens that forms an image of light passing through the objective lens, and a mirror that reflects light from the additional objective lens toward the additional objective lens, light from the particle passing through a different position in the flow channel passes through the objective lens and the additional objective lens, and then is focused at a different image forming position, and the mirror has a plurality of reflective surfaces respectively positioned at different image forming positions.
