This enables proper alignment in observation of particles trapped in the vicinity of the electrodes 72 in the substrate 9 such as a micro-channel chip.

A light wavefront measurement device includes a lens array, a light receiving sensor, and a wavefront shape calculation part. The lens array focuses measurement light for each region of the wavefront of the measurement light. The light receiving sensor receives multiple light spots focused by the lens array to output an electrical signal for pixels where the amount of received light has changed. The electrical signal indicates the direction of increase or decrease in the amount of received light and the time at which the amount of received light has changed. The wavefront shape calculation part calculates the wavefront shape of the measurement light, based on the electrical signal outputted from the light receiving sensor. The amount of information outputted from the light receiving sensor is smaller than that outputted for all pixels. The light receiving sensor is hence capable of outputting information about the displacement of the light spots with high time resolution. This allows the measurement of the wavefront shape of the measurement light with high time resolution, based on the information outputted from the light receiving sensor.

A temperature measurement wafer (1) includes a temperature sensor (3), a transmission unit (8), and a battery substrate (7). The transmission unit (8) wirelessly transmits temperature data of a temperature measurement subject measured by the temperature sensor (3) to the temperature measurement wafer (1). That is, the temperature measurement wafer (1) wirelessly transmits information to the outside, a decrease in operation efficiency caused by a communication wire can be avoided. The battery substrate (7) supplies power to each of the temperature sensor (3) and the transmission unit (8) using an all-solid-state secondary battery (21). Using the all-solid-state secondary battery (21) makes it possible to operate the temperature measurement wafer (1) without deteriorating its performance even under a higher temperature condition. Thus, the temperature measurement wafer (1) can be used under a higher temperature condition while improving the operation efficiency of the temperature measurement wafer (1).
