Publication number: 20240323543Abstract: According to an aspect, a detection device includes: a planar detection device including photodetection elements arranged in a planar configuration; a light-transmitting placement substrate to place thereon objects to be detected; and light sources provided correspondingly to the photodetection elements. The planar detection device, the placement substrate, and the light sources are arranged in the order as listed. The light sources include first light sources that are separately arranged and second light sources that are arranged adjacent to the respective first light sources. The detection device has: a first period in which the first light sources are on and the second light sources are off; and a second period in which the second light sources are on and the first light sources are off. The detection device is configured to combine a first image detected in the first period with a second image detected in the second period.Type: ApplicationFiled: March 18, 2024Publication date: September 26, 2024Inventors: Tomoyuki ISHIHARA, Tomoya TEZEN, Daisuke HAMANO, Naoyuki ASANO, Kaoru ITO, Akihiko FUJISAWA
