Abstract

A spectrometer system may be used to determine one or more spectra of an object, and the one or more spectra may be associated with one or more attributes of the object that are relevant to the user. While the spectrometer system can take many forms, in many instances the system comprises a spectrometer and a processing device in communication with the spectrometer and with a remote server, wherein the spectrometer is physically integrated with an apparatus. The apparatus may have a function different than that of the spectrometer, such as a consumer appliance or device.

First claim

What is claimed is:

1. A system to measure spectra of a sample, comprising:
a compact spectrometer to measure a spectrum of the sample;
wherein the spectrometer is functionally integrated with a smartphone, and wherein the spectrometer is configured to utilize information obtained with a functional feature of the smartphone to improve the measurement of the spectrum of the sample;
wherein the functional feature comprises a camera, an accelerometer, a global positioning system (GPS), or any combination thereof; and
wherein the camera is configured to provide an indication layer to a user of the spectrometer in order to assist the user in adjusting a position or orientation of the spectrometer with respect to the sample.

2. The system of claim 1 , wherein the compact spectrometer or a computing device in communication with the spectrometer is configured to utilize the camera to improve the measurement of the spectrum of the sample.

3. The system of claim 1 , wherein the compact spectrometer or a computing device in communication with the spectrometer is configured to utilize the camera of the smartphone to determine a distance between the spectrometer and a sample.

4. The system of claim 3 , wherein the compact spectrometer or a computing device in communication with the spectrometer is configured to utilize the camera of the smartphone to set an offset angle between an optical axis of the compact spectrometer and an illumination module.

5. The system of claim 1 , wherein the compact spectrometer or a computing device in communication with the spectrometer is configured to utilize the camera of the smartphone to determine a distance between the camera and the sample.

6. The system of any one of claims 3 - 5 , wherein the compact spectrometer or another computing device in communication with the spectrometer is configured to provide a visualization of the parallax between an illumination module of the spectrometer and the camera of the smartphone on the smartphone camera display.

7. The system of claim 1 , wherein the spectrometer or a computing device in communication with the spectrometer is configured to utilize the camera to determine a portion of the sample from which the spectrum was measured.

8. The system of claim 1 , wherein the camera is configured to obtain an image of the sample comprising a plurality of different components, and wherein the spectrometer is configured to measure at least a subset of the plurality of different components included in the image.

9. The system of claim 1 , wherein the compact spectrometer or a computing device in communication with the spectrometer is configured to utilize the camera to estimate a volume of a component of the sample using a vision algorithm.

10. The system of claim 1 , wherein the spectrometer or a computing device in communication with the spectrometer is configured to utilize an image of the sample generated by the camera and the spectrum of the sample to identify the sample.

11. The system of claim 1 , wherein the compact spectrometer or a computing device in communication with the spectrometer is configured to utilize the camera to estimate the relative movement of the sample surface with respect to the compact spectrometer during measurement.

12. The system of claim 11 , wherein the compact spectrometer or a computing device in communication with the spectrometer is configured to utilize the camera or the accelerometer to provide instructions to a user of the spectrometer to repeat a measurement of the sample if the detected relative movement exceeds a set threshold value.

13. The system of claim 1 , wherein the compact spectrometer or a computing device in communication with the spectrometer is configured to utilize the camera or the accelerometer to distinguish between sample movement and smartphone movement.

14. The system of claim 1 , wherein the compact spectrometer or a computing device in communication with the spectrometer is configured to utilize the camera or the accelerometer to correct for spectrometer motion during the measurement of the spectrum of the sample.

15. The system of claim 1 , wherein the compact spectrometer or a computing device in communication with the spectrometer is configured to utilize the global positioning system (GPS) to determine the identity of the sample.

16. The system of claim 1 , wherein the compact spectrometer comprises communication circuitry such that the spectrometer can transmit and receive data to and from the smartphone.
