Bioluminescence imaging (BLI) is a technology developed over the past decades (1990's and onward).[1][2][3][when?] that allows for the noninvasive study of ongoing biological processes[4][1][5][6][7] Recently, bioluminescence tomography (BLT) has become possible and several systems have become commercially available. In 2011, PerkinElmer acquired one of the most popular lines of optical imaging systems with bioluminescence from Caliper Life Sciences.[8]
