Abstract

A goggle system is provided. The goggle system includes a computing device, a goggle device configured to be worn by a user and including a detector configured to simultaneously acquire image data of a subject in a first image mode and a second image mode, at least one eye assembly configured to display at least one of an image in the first image mode, an image in the second image mode, and a hybrid image including pixels of image data from the first image mode and pixels of image data from the second image mode, and a communications module configured to transmit acquired image data from the goggle device to the computing device.

First claim

The invention claimed is:

1. A goggle device configured to be worn by a user and comprising:
a detector comprising at least one imaging sensor and configured to simultaneously acquire image data from a plurality of fluorescent molecules, a plurality of luminescent materials, or a combination thereof in a state of excitation caused by a fluorescence excitation light source, and from visible light illuminated by a white light source.

2. The goggle device of claim 1 , further comprising at least one eye assembly configured to display pixels of the acquired image data in real-time.

3. The goggle device of claim 1 , further comprising a control module which interfaces between the imaging sensor and a computing device.

4. The goggle device of claim 3 , wherein the control module comprises a field-programmable gate array (FPGA).

5. The goggle device of claim 4 , wherein the FPGA has universal serial bus (USB) communication capabilities.

6. The goggle device of claim 4 , wherein data received by the imaging sensor is read out in multiple stages.

7. The goggle device of claim 4 , wherein data from the imaging sensor is read out via a state machine implemented on the FPGA.

8. The goggle device of claim 4 , wherein the data are stored in a first in first out (FIFO) process and transferred to a first synchronous dynamic random-access memory (SDRAM) chip in the control module.

9. The goggle device of claim 4 , wherein the control module comprises a first synchronous dynamic random-access memory (SDRAM) chip to store pixel data from the imaging sensor and a second SDRAM chip to transfer the data to an output first in first out (FIFO) process on the FPGA.

10. The goggle device of claim 3 , wherein the control module further comprises a data compression chip.

11. The goggle device of claim 1 , further comprising an autofocus feature.

12. The goggle device of claim 11 , wherein the autofocus feature comprises a zoom lens comprising a piezo actuator.

13. The goggle device of claim 11 , wherein the autofocus feature comprises a liquid lens having a variable, voltage-dependent focal length.

14. A goggle system comprising:
a computing device;
a goggle device configured to be worn by a user; and
a detector comprising at least one imaging sensor and configured to simultaneously acquire image data from a plurality of fluorescent molecules, a plurality of luminescent materials, or a combination thereof in a state of excitation caused by a fluorescence excitation light source, and from visible light illuminated by a white light source.

15. The goggle system of claim 14 , further comprising at least one eye assembly configured to display pixels of the acquired image data in real-time.

16. The goggle system of claim 14 , further comprising an endoscope.

17. The goggle system of claim 14 , further comprising a control module which interfaces between the imaging sensor and the computing device.

18. The goggle system of claim 17 , wherein the control module comprises a field-programmable gate array (FPGA).

19. The goggle system of claim 18 , wherein data received by the imaging sensor is read out in multiple stages.

20. The goggle system of claim 18 , wherein data from the imaging sensor is read out via a state machine implemented on the FPGA.

21. The goggle system of claim 18 , wherein the data are stored in a first in first out (FIFO) process and transferred to a first synchronous dynamic random-access memory (SDRAM) chip in the control module.

22. The goggle system of claim 18 , wherein the control module comprises a first SDRAM chip to store pixel data from the imaging sensor and a second SDRAM chip to transfer the data to an output FIFO on the FPGA.

23. The goggle system of claim 17 , wherein the control module further comprises a data compression chip.

24. The goggle system of claim 14 , further comprising an autofocus feature.
