An optical detection type ultrasonic receiving apparatus in which SN ratio of the detection signal is increased while preventing the apparatus from increase of size and cost. The preferred particulate is aluminosilicate microspherers and the binder is preferably based on silica. The processing may comprise two or more data transformation techniques coordinated in time, concurrently executing autonomous sets of instructions, and provided in a manner preserving the sequence of processing and storing the processed data chunks. A subsequent laminate is disposed on the plurality of alternating laminates.
