Parallel sensing configuration covers spectrum and colorimetric quantities with spatial resolution

摘要

An optical test equipment/method for display testing that features parallel testing/sensing configuration that covers spectrum and colorimetric quantities with spatial resolution is disclosed. In one embodiment, a spectra-camera, which is a hybrid system consisting of both a single-point spectrometer and an imaging colorimeter, can be configured for concurrent display artifact and parametric testing. An aperture mirror with a hole in the middle splits an image of a test display into two parts. One part of the image passes through the hole and is directed to the spectrometer for display parametric testing. The rest of the image is reflected off the aperture mirror for concurrent display artifact testing with the colorimeter. In another embodiment, a beam splitter can be used instead of an aperture mirror. In yet another embodiment, the single-point high accuracy spectrometer can be used to calibrate the low accuracy imaging colorimeter.

1. A method for performing an optical test, the method comprising:
by a spectra camera:
receiving a sample of light to form an image;splitting the image into a first image and a second image;using a narrowband device to measure a first area of the first image to identify parametric data;using a broadband device to measure a second area of the second image to identify display artifacts, andconcurrently calibrating, using the sample of light, the broadband device and the narrowband device based on measurements of the first area and the second area.
