To evaluate technologies for ILC calorimetry, the CALICE collaboration has constructed a
prototype of a highly granular analogue hadron sampling calorimeter with small scintillator
cells, individually read out by silicon photomultipliers. This detector has been tested
extensively in particle beams at DESY, at CERN and at Fermilab. A digital hadron calorimeter
based on RPC read-out, is currently under construction, with first test beam results from
small prototypes already available. The imaging capabilities of these calorimeters provide
three dimensional information of hadronic showers with unprecedented resolution and will thus help to constrain hadronic shower models in simulation codes. The high granularity also opens up the possibility for improved energy resolution achieved with energy weighting algorithms
and allows for novel calibration methods using minimum ionizing tracks identified within
hadronic showers. We present results from the analysis of electromagnetic and hadronic
events. Studies ranging from longitudinal and transverse shower profiles, compared to
simulations with a variety of different models, to the investigation of the energy resolution and the linearity of the detector response, will be discussed.
