Abstract

In one aspect, a prism is used to separate white light into individual color components, which are used to illuminate an object in sequence. This can be effected by rotating the prism. Reflections from the object are captured by a high resolution black and white camera. A frequency detector is used to also receive the individual colors that illuminate the object so that the high-resolution pixels from the black and white camera can be correlated, for each captured value, to the specific color reflected from the object that created the pixel. In this way, the color spectrum of the object can be measured with high precision. Other examples that use stationary prisms also are disclosed. Examples are disclosed in which the prism(s) receive white light from the object and spread it in color components onto the imager.

Dependent claims

Apparatus comprising:

at least one beam divider to receive white light and output separate color components of the white light to illuminate an object with a single one of the color components at a time, such that the object is illuminated with a first color component and no other color components at a first time and a second color component and no other components at a second time;
at least one black and white imager configured for receiving, from the object, reflections of the separate color components of the white light;
and
at least one wavelength reference receiver (WRR) receiving from the beam divider the separate color components of the white light, such that the WRR receives the first color component and no other color components at the first time and the second color component and no other components at the second time, such that information from the WRR can be correlated with pixel information from the black and white imager.
