Title: Device for evaluating optical recording material
Inventor: MIYAMOTO NORIFUMI
IPC: G01N21/55
Filed: 1987-03-06
Abstract: PURPOSE:To permit quick and easy measurement of the optical characteristics of an optical recording medium in relation to temp. by using a laser as a light source for heating and condensing the laser to a micro-spot by means of a lens. CONSTITUTION:A light projection part 52 has two kinds of light sources; a laser light source 60 for heating and a laser for detecting a change in reflectivity. The laser light emitted from the light source 60 is converted by a modulator 59 utilizing an electro-optic effect to pulses which are focused onto a sample 64 to be measured through an optical head 58. The laser is focused to several micron sizes at this point and attains several hundred temp. instantaneously. The IR rays radiated from the heating part of the sample 64 are condensed by a lens 54 of a reflection type and enter an IR detector 53. The signal from the detector 53 is amplified by an amplifier 56 and is fed to a data recording part 57. On the other hand, the laser for detecting the change in the reflectivity forms a spot similarly on the sample surface. The spot positions of the laser 60 and the laser for detecting the change in the reflectivity on the sample surface are matched in order to exactly measure the reflectivity of the sample during heating.
