Optical measurement systems and methods thereof

An optical measurement system comprising:

• a reflective structure comprising at least two mirrored outer surfaces on opposing sides of an axis which extends in a direction out from the reflective structure towards a target, wherein the reflective structure is configured to be spaced from the target;
• an input system comprising at least one input optical element positioned to receive and direct source light towards one of the mirrored surfaces, wherein the one of the mirrored surfaces is positioned to reflect the source light towards the target;
• an output system comprising at least one output optical element positioned to receive and output converging light from reflected light that comprises measurement data related to the target, wherein the reflected light is the source light reflected from the target via the other one of the mirrored surfaces and is without substantial overlap with the source light,
• a light source positioned to direct source light on the input system;
• a spectrograph with an image sensor coupled to receive the output converging light, wherein the spectrograph is configured to spectrally disperse the output converging light on the image sensor to generate spectral image data;
• and
• a processor coupled to the image sensor to receive and process the generated spectral image data to determine the measurement data.
