Classification: CPC G  H | IPC G  H

Claim 16:
17. The method of claim 5, further comprising an alignment step prior to assessing the reference illumination landscape, the alignment step being selected from:
a. an active area defining step comprising:
i. successively activating each pixel of the pSLM to transmit light while all other pixels block at least a portion of light,
ii. capturing an image with the image sensor for each successively activated pixel, and
iii. associating each pixel of the pSLM with those pixels of the image sensor that are affected by their activation; and

b. a center alignment step comprising:
i. activating a plurality of pixels encompassing the center of the pSLM,
ii. capturing an image with the image sensor for the activated plurality of pixels of step b.i,
iii. comparing the affected area of the image sensor per step b.ii. with the center of the image sensor, and, if the affected area is not centered on the image sensor, and
iv. moving the pSLM in a centering direction; and

c. a pixel alignment step comprising:
i. rotating the pSLM so that x and y directions of the pSLM pixels are respectively aligned with x and y directions of the image sensor; and

d. combinations thereof.
