Interesting question for DemoMakers - can you detect voter presence using contrast sensor and not a full light sensor

(01) light sensor tells light intensity. Contrast sensor gets light REFLECTED by a paper , and gives contrast ratio between black dots and white spaces on paper.
.
(02) Now in custom made contrast sensor can do both - get light intensity and also measure contrast.

(03) But say vvpat has standard contrast sensor , which measures only contrast , when paper is out. And when contrast is measured , light intensity will be known. So voter presence can be known
.
(04) but slip is already out !!! And say there is no backfeed. And voter must be shown paper cut dop scroll .

(05) so how can vote now be stolen ?

(06) how can vote be stolen even with colorless glass ?
