an imaging sensor configured to acquire image data for an imaged object;
a multi-band wavelength filter disposed to filter light detected by the imaging sensor; and
a motion stage configured to cause relative motion between the imaged object and the multi-band wavelength filter at a motion rate that is based on a frame rate of the imaging sensor and a number of wavelength bands of the wavelength filter utilized to filter light detected by the imaging sensor.

2. The system of claim 1, wherein the motion rate is set such that light detected by the imaging sensor corresponding to a portion of the imaged object is filtered by successive wavelength bands of the wavelength filter for successive frames capturing the portion of the imaged object.

3. The system of claim 2, wherein the motion rate is further based on an imaging sensor resolution and a sensor spatial resolution.

4. The system of claim 3, wherein the motion rate is determined as:
,
wherein is the motion rate, is the frame rate of the imaging sensor, is the imaging sensor resolution, is the number of wavelength bands of the wavelength filter utilized to filter light detected by the imaging sensor, and is the sensor spatial resolution.

5. The system of claim 4, wherein the imaging resolution is measured based on spatial registration of a reference pattern image captured via the imaging sensor.

6. The system of claim 3, wherein the wavelength filter is configured such that each of the number of wavelength bands filters light detected by equal numbers of the pixel lines of the imaging sensor.

7. The system of claim 6, wherein each of the number of wavelength bands filters light detected by one pixel line of the imaging sensor.

8. The system of claim 1, wherein the motion stage is configured to cause motion of the imaged object.

9. The system of claim 1, wherein the motion stage is configured to cause motion of the multi-band wavelength filter.

11. The system of claim 1, wherein the motion stage causes relative translation between the imaged object and the multi-band wavelength filter.

12. The system of claim 1, further comprising:
a hardware processor configured to perform operations comprising:
obtaining the image data for the imaged object from the imaging sensor;
generating pixel-resolution wavelength-dependent response data for the imaged object; and
outputting the pixel-resolution wavelength-dependent response data.

13. The system of claim 1, further comprising:
a hardware processor configured to generate a user interface for a user to modify the motion rate; and
a display device operatively connected to the hardware processor to display the user interface for the user to modify the motion rate.
