Abstract
Example embodiments described herein involve a system for testing a light-emitting module. The light-emitting module may include a mounting platform configured to hold a light-emitting module for a camera. The mounting platform may also be configured to rotate. The system may further include a housing holding a plurality of photodiodes arranged in an array over at least a 90 degree arc of a hemisphere. The system may also include a controller configured to control the photodiodes and the rotation of the mounting platform.
Claims20
A system comprising:
- a mounting platform configured to hold a light-emitting module, wherein the mounting platform is configured to rotate;
- a housing holding a plurality of photodiodes;
- and
- a controller configured to control operation of the system for testing the light-emitting module to carry out a plurality of operations comprising:
- determining an illumination pattern of the light-emitting module based on a plurality of directional light intensities of light emitted from the light-emitting module sensed by the photodiodes.
The system of claim 10, wherein sensing, with the photodiodes, the plurality of directional light intensities of the light emitted from the light-emitting module is performed while rotating the light-emitting module.
A system comprising:
- a mounting platform configured to hold a control light source comprising a predetermined light intensity;
- a housing holding a plurality of photodiodes;
- and
- a controller configured to control operation of the system for testing the light-emitting module to carry out a plurality of operations comprising:
- sensing, with the plurality of photodiodes, a plurality of directional light intensities of the light emitted from the control light source;
- and
- determining whether any of the plurality of directional light intensities sensed with the photodiodes is associated with an error based on the predetermined light intensity of the control light source.
