Abstract
An apparatus for the measurement of optical sensor performance includes a light emitter, a focuser and a controller. The optical sensor comprises a plurality of pixels, which may be arranged as a pixel array. The light emitter projects a light spot onto the sensor. The focuser focuses the light spot onto a specified portion of the sensor in accordance with a control signal. The controller analyzes an output signal of the optical sensor, and generates the control signal to an accuracy substantially confining the light spot to a single pixel in accordance with the analysis.
Claims23
An apparatus for the measurement of optical sensor performance, wherein said optical sensor comprises a plurality of pixels, comprising:
- a light emitter, configured for projecting a light spot onto said sensor;
- a focuser associated with said light emitter, configured for focusing said light spot onto a specified portion of said sensor in accordance with a control signal;
- and
- a controller associated with said focuser, configured for analyzing an output signal of said optical sensor and for generating, in accordance with said analysis, said control signal to an accuracy substantially confining said light spot to a single pixel, thereby to provide a per-pixel accuracy of measurement from said output signal.
A method for measuring optical sensor performance, wherein said optical sensor comprises a plurality of pixels, said method comprising:
- projecting a light beam from a light source;
- focusing said light beam to form a light spot on a specified portion of said sensor;
- analyzing an output signal of said optical sensor in response to said light spot;
- and
- adjusting a focus of said light spot to an accuracy substantially confining said light spot to a single pixel, in accordance with said analyzing, thereby to provide a per-pixel accuracy of measurement from said output signal.
