As the population ages, the number of patients with diabetes continues to rise. The method currently used to perform blood sugar measurements for such patients is to measure the glucose level in a blood sample.

Problems with collecting blood samples

• Pain and mental stress of blood sampling
• Risk of infection
• Sterilization of the needle after use

To eliminate these problems, reduce the incidence of diabetes and improve the quality of life for diabetic patients, Aime Technology has been developing a new method for measuring blood sugar level that will be effective for diabetes prevention and treatment.

This film thickness meter provides a non-contact, non-destructive method of measuring film thickness. Greater compactness and resistance to noise interference was achieved by employing a laser interferometer and a superluminescent diode (SLD) together with optical fiber in place of the space propagation path of a conventional optical interferometer. This reliable, easy to use film thickness meter can automatically measure up to millimeter-order film thicknesses and layer thicknesses with a resolution of 0.01 millimeter.

• Non-contact, non-destructive measurement of film thickness
• Able to measure extremely small sections
• Able to perform remote measurement
• Easy maintenance

This piezoelectric optical path length adjustment unit is comprised of optical fiber wound around cylindrical PZT (lead zirconate titanate) piezoelectric elements. By inserting it into an optical fiber circuit, the optical fiber length adjustment unit can be used for a wide range of applications, such as stabilizing the optical fiber length or optical phase, or performing high-speed scanning. Employing computer control, it is also ideal for fine adjustment of optical fiber length and for repeated quick changes in optical fiber length modulation at the desired waveform.

• Voltage-controlled fine adjustment of optical fiber length
• Easy connection
• Stable and reliable; requires no adjustment
