Abstract— We propose a straightforward method to measure the absolute throughput of an LCoS microdisplay. The method requires two measurements. The first measurement is of the lumens delivered from a testbed, which includes the microdisplay under test, with a folded light path. The second measurement is of the lumens delivered by the unfolded testbed with the microdisplay removed. This second measurement is used to normalize the first to obtain a fractional transmission that a designer can use to make a meaningful prediction of the system brightness of a LCoS‐based projection system.
