A new lens-free imaging system uses software to see finer details from farther away than optical systems ever could before.

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The approach uses multiple sensors to collect raw light patterns independently, then ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

Apple is working on new fingerprint sensing technology that could work through an iPhone display by taking advantage of off-axis angular light. In a new patent application, Apple hones in on optical ...
