Abstract
Embodiments of the present invention relate to holographically illuminated imaging devices including a holographic element for transforming an illumination beam into a focal array of light spots, a scanning mechanism for moving an object across one or more light spots in the focal array of light spots, and a light detector for detecting light associated with the focal array of light spots and generating light data associated with the received light.
Claims16
A holographically illuminated imaging device, comprising:
- a holographic element configured to transform an illumination beam from an illumination source into a focal array of light spots;
- a scanning mechanism configured to move an object across one or more light spots in the focal array of light spots;
- and
- a light detector configured to detect light associated with the focal array of light spots, and generate light data associated with the received light.
A holographically illuminated imaging device, comprising:
- a body defining a fluid channel;
- a holographic element configured to transform an illumination beam from an illumination source into a focal array of light spots;
- a beam splitter configured to reflect the focal array of light spots into the fluid channel wherein a flow in the channel moves an object across one or more light spots in the focal array of light spots, the beam splitter further configured to transmit light altered by the object;
- and
- a light detector configured to detect light associated with the focal array of light spots, and generate light data associated with the received light.
A holographically illuminated imaging device, comprising:
- a holographic element configured to transform an illumination beam into a plurality of focal arrays of light spots at different focal planes;
- a scanning mechanism configured to move an object across one or more light spots in the plurality of focal arrays of light spots;
- and
- a light detector configured to receive light associated with the plurality of focal arrays of light spots, and generate light data associated with the received light.
A system, comprising:
- a holographically illuminated optofluidic imaging device including
- a holographic element configured to transform an illumination beam from an illumination source into a focal array of light spots,
